Thesis (MBA)--Stellenbosch University, 2005.<br>AENGLISH ABSTRACT: With the advent of the internet a few years ago many online communities have
been formed from traditional communities. The ability of a traditional community
to transform into an online community depends on the type of interaction that is
required by that particular community.
Based on the arguments of various critics of the online community, this study will
focus on the feasibility of transforming the golfing fraternity from a traditional to
an online community. The study project therefore proposes to understand online
communities as a subset within the general concept of community. It will be
determined if the golfing community that currently falls into the traditional
framework is open to create itself into a modern online community. The
characteristics of traditional communities include bonding, sharing of information
and other items of common interest which is similar for online communities.
It is within this objective that the characteristics of online communities and the
relationship between traditional and modern communities will be discussed. The
first phase was to develop a questionnaire based on desirability and expectations
of an online golfing community and for the purposes of this study, the research
population comprised of the registered golf members of golf clubs in the Western
Province Golf Union (WPGU) in the Western Cape. Furthermore there is within
the Western Cape golfing community, possibly scope for a universal
understanding of this community as a whole.
Golfing communities can be defined through their unique characteristics. Golf
communities are traditional communities that have evolved over time. Since
modern communities are no longer constrained by geography the question arises
whether, golf which has all the characteristics of a traditional community would
be able to migrate to a modern online community. From the empirical study it became evident that the current golf community is
open to using the internet to gain information on golf. The potential for the
success of an online golfing community especially an interactive one in the future
is great as the survey results show that the current membership are open to the
idea of an online community.FRIKAANSE OPSOMMING:<br>AFRIKAANSE OPSOMMING: Met die koms van die internet 'n paar jaar gelede, is baie aanlyn gemeenskappe
vanaf tradisionele gemeenskappe ontwikkel. Die vermoe van tradisionele
gemeenskappe om na aanlyn gemeenskappe te verander, is afhanklik van die
tipe interaksie wat in daardie spesifieke gemeenskap benodig word.
In die lig van 'n literatuurstudie oor die verskillende standpunte oor aanlyn
gemeenskappe, is 'n ondersoek gedoen na die aanneemlikheid van die
verandering van 'n tradisionele gemeenskap, naamlik die gholf gemeenskap, na
'n aanlyn gemeenskap. Die studie het daarom ten doel om aanlyn
gemeenskappe te ondersoek as 'n sub-afdeling van die algemene gemeenskap
konsep. Deel van die ondersoek behels die openheid van die gholf gemeenskap,
'n tipiese tradisionele gemeenskap, om 'n moderne virtuele gemeenskap te vorm.
Die samestelling van 'n tradisionele gemeenskap beskik oor soortgelyke
eienskappe as die van 'n aanlyn gemeenskap soos verbondenheid, die deel van
inligting en ander items van gemeenskaplike belang.
Dit is die doelwit van hierdie studie om die eienskappe van die aanlyn
gemeenskap en die verwantskap tussen tradisionele en aanlyn gemeenskap te
bespreek. Die eerste fase, was die ontwikkeling van 'n vraelys met klem op die
wenslikheid en behoeftes van 'n aanlyn gholf gemeenskap. Die populasie vir die
studie was lede van die Westelike Provinsie Gholf Vereniging (WPGU) in die
Wes Kaap. Die data wat ontgin is uit die navorsing van die WPGU kan ook
moontlik bydra tot 'n verstaan van die universele gholf gemeenskap in Suid
Afrika.
Gholf gemeenskappe kan gedefinieer word deur hulle unieke eienskappe. Hulle
is tradisionele gemeenskappe wat ontwikkel het deur die jare. Sedert moderne
gemeenskappe nie langer geografies beperk is nie moet die vraag gestel word of 'n tradisionele gholf gemeenskap tot 'n moderne aanlyn gemeenskap kan
ontwikkel?
Uit die literatuurstudie het die duidelik geword dat die huidige gholf gemeenskap
oop is vir die gebruik van die internet om inligting oor gholf in te win. In die lig van
huidige lede se aanvaarding van aanlyn gemeenskappe lyk die potensiaal en
moontlikheid vir die sukses van 'n aanlyn gholf gemeenskap in die toekoms
belowend.

Online communities are growing at a phenomenal rate and with the large number of users these communities contain, attackers are drawn to exploit these users. Denial of information (DoI) attacks and information leakage attacks are two popular attacks that target users on online communities. These information based attacks are linked by their opposing views on low-quality information. On the one hand denial of information attacks which primarily use low-quality information (such as spam and phishing) are a nuisance for information consumers. On the other hand information leakage attacks, which use inadvertently leaked information, are less effective when low-quality information is used, and thus leakage of low-quality information is prefered by private information producers.
In this dissertation, I introduce techniques for preventing abuse against these attacks in online communities using meta-model classification and information unification approaches, respectively. The meta-model classification approach involves classifying the ``connected payload" associated with the information and using the classification result for the determination. This approach allows for detection of DoI attacks in emerging domains where the amount of information may be constrained. My information unification approach allows for modeling and mitigating information leakage attacks. Unifying information across domains followed by a quantificiation of the information leaked, provides one of the first studies on users' susceptibality to information leakage attacks. Further, the modeling introduced allows me to quantify the reduced threat of information leakage attacks after applying information cloaking.

Smith, Matthew Scott. "Social Capital in Online Communities." BYU ScholarsArchive, 2011. https://scholarsarchive.byu.edu/etd/2730.

Social capital is the value of the relationships we create and maintain within our social networks to gain access to and mobilize needed resources (e.g., jobs, moral support). Quantifying, and subsequently leveraging, social capital are challenging problems in the social sciences. Most work so far has focused on analyses from static surveys of limited numbers of participants. The explosion of online social media means that it is now possible to collect rich data about people's connections and interactions, in a completely ubiquitous, non-intrusive manner. Such dynamic social data opens the door to the more accurate measuring and tracking of social capital. Similarly, online data is replete with additional personal data, such as topics discussed in blogs or hobbies listed in personal profiles, that is difficult to obtain through standard surveys. Such information can be used to discover similarities, or implicit affinities, among individuals, which in turn leads to finer measures of social capital, including the often useful distinction between bonding and bridging social capital. In this work, we exploit these opportunities and propose a computational framework for quantifying and leveraging social capital in online communities. In addition to being dynamic and formalizing the notion of implicit affinities, our framework significantly extends current social network analysis research by modeling access and mobilization of resources, the essence of social capital. The main contributions of our framework include 1) hybrid networks that provide a way for potential and realized social capital to be distinguished; 2) the decoupling of bonding and bridging social capital, a formulation previously overlooked which coincides with empirical evidence; 3) the unification of multiple views on social capital, in particular, the seamless integration of resources. We demonstrate the broad applicability of our framework through a number of representative, real-world case studies to test relevant social science hypotheses. Assuming that the extraction of implicit affinities may be useful for community building, we built a large social network of blogs from an active, tech-oriented segment of the Blogosphere, using cross-references among blogs. We then used topic modeling techniques to extract an implicit affinity network based on the content of the blogs, and showed that potential sub-communities could be formed through increased bonding. A widespread assumption in sociology is that bonding is more likely than bridging in social networks. In other words, people are more likely to seek out others who are like them than attempt to link to those they share little or nothing with. We wanted to test that hypothesis, particularly in the context of online communities. Using Twitter, we created an experiment where hand-crafted accounts would tweet at regular intervals and use varied following strategies, including following only those with maximum affinity, following only those with no affinity, following random users, etc. Using the number of follow-backs as a surrogate for social capital, we showed that the assumed physical social behavior is also prevalent online, p < 0.01. There is much interest in computational social science to compare physical and cyber behaviors, test existing hypotheses on a large scale and design novel experiments. The advent of social media is also impacting public health, with growing evidence that some global health issues (e.g., H1N1 outbreak) may be discovered and tracked more efficiently by monitoring the content of social exchanges (e.g., blogs, tweets). In collaboration with colleagues from Health Sciences, we wanted to test whether broadly applicable health topics were discussed on Twitter, and to design and guide the process of discovering such themes. We gathered a large number of tweets over several regions of the United States over a one-month period, and analyzed their content using topic modeling techniques. We found that while clearly not a mainstream topic, health concerns were non-negligible on Twitter. By further focusing on tobacco, we discovered several subtopics related to tobacco (e.g., tobacco use promotion, addiction recovery), which indicate that analysis of the Twitter social network may help researchers better understand how Twitter promotes both positive and negative health behaviors. Finally, in collaboration with colleagues from Linguistics, we wanted to quantify the effect of social capital on second language acquisition in study abroad. Using questionnaire data collected from about 200 study abroad participants, we found that students participating in bridging relationships had significantly higher levels of language improvement than their counterparts, F(1,201) = 12.53, p < .0001.

Online communities have become a part of everyday life for many people. The members of the communities use them to keep in touch with family and friends, do business, look for jobs, play games, and more, both savory and unsavory. The ease of sharing personal information comes with the subsequent risk of having that information exposed publically or even stolen. The purpose of this study was to explore how much awareness of the risks affects a person’s decision to post personal information to an online community.
Chapter I introduces the concepts and issues that will be investigated by this paper. Chapter II is a review of the literature on risk. Chapter III explains the model that was developed and used determine the relationships between risk perception, attitude, fear, and information revelation. Chapter IV explains the methods used to gather the data and what data was gathered. Chapter V contains the analysis of the data collected. Chapter VI contains the conclusion drawn from the data, implications for the research, and directions for future research.

This thesis advances the concept of consumer engagement as a valid approach to the conceptualisation and measurement of Online Brand Community (OBC) participation. Against the background of rapid technological advances affecting the way consumers interact online, this thesis posits that past representations of OBC participation fail to adequately capture OBC participation. It further argues that consumer engagement offers a new analytical lens, which is more responsive to the interactive, social and multidimensional nature of OBCs. The thesis conceptualises consumer engagement in OBC as an affective, cognitive and behavioural phenomenon whereby a consumer is engaged both with the other members of the OBC and with the focal brand. It then identifies antecedents and outcomes of consumer engagement in English-speaking OBC. The measurement and conceptual model are tested using data from OBC participants. In particular, two original scales of consumer engagement are developed. The conceptual model is tested using structural equation modelling techniques, and the results largely support the research hypotheses. The results show that online interaction propensity, attitude toward OBC participation and product involvement positively relate to OBC engagement, and that online brand engagement is positively related to product involvement and OBC engagement. Online brand engagement shows positive correlations with brand trust, commitment and loyalty. Group invariance is largely achieved using data from French OBCs, which contribute to validating the English sample results. Overall, the thesis conceptually and empirically contributes to the burgeoning literature on consumer engagement in OBC and enhances our understanding of OBC participation. The study provides an improved, more online-relevant conceptualisation and measurement of consumer engagement and identifies its key individual drivers and relational outcomes. These findings also provide strategic implications for the community of OBC practitioners.

The concept of communities and the interaction between people are not new concepts. People have always gathered around common conditions shared by those in the group such as shared emotions, interests, beliefs and needs. It is however the way we interact, with whom we interact, and when and where these meetings take place which has changed. This has been a direct result of the development of the internet and exacerbated with the move to the second phase of internet development. This second phase of internet development provides users with real-time functionality enabling interaction with global users in a virtual environment. This interaction is termed online social networking and takes place in online communities.Online communities present opportunities for marketers as they give rise to a virtually unlimited number of different consumers, structured around finer consumption and marketing interests. Research indicates that online community users are market-oriented and therefore online communities provide a meaningful medium of exchange for these users. The challenge for companies today has been trying to develop ways to capitalise on this trend and raise their competitive advantage. However, in order to effectively understand these users, an understanding of their characteristics is fundamental to the development of any tailored marketing campaign. This thesis therefore aims to shed an insight into a segmentation model designed for online communities - firstly by empirically testing it and secondly, by enriching the data with a typology of online buying behaviour characterised by psychographic and behaviour variables. Therefore the research question posed is “Can online community users be classified by their online buying behaviours so that they are useful to marketers?”.The empirical data was gathered quantitatively through an online questionnaire designed to classify the respondents into meaningful segments and clusters. The report reflects a social constructionist methodology where the results have been interpreted and given meaning. The report is based on the segmentation models presented by Kozinets’ ‘virtual communities of consumption’ and Barnes et al. typology on online buying behaviour. This report combines the two models in order to enrich the segmentation model presented by Kozinets’ with attributes of online buying behaviour in order to provide a more comprehensive understanding of online community users. The results indicated that the four online user profiles defined in Kozinets’ model did not show differences in their online purchasing behaviour. Rather all online community users could be categorised by Barnes et al’s three clusters of online buying behaviour.

Special interest online communities refer to groups of people who share a concern orpassion for something they do and learn how to do it better as they interact regularly,with some of the interaction being technology mediated. The Uppsala UniversityACM-W Student Chapter is an online community, run by a student group, thatpromotes gender equality in Computer Science and Information Technology atUppsala University. This thesis investigates what makes a website an online community by determininghow community building works and how it could be used productively. The UppsalaUniversity ACM-W Student Chapter's ambition is to be a successful onlinecommunity and attract both short-time members and long-time members to engagein their organization. It should also be easy to keep international contact with similarchapters through the website. Hence an evaluation of the chapters website(uu.acm.org) was conducted for this thesis, involving interviewing members of thechapter. The focus of the evaluation was to investigate how well the UU ACM-Wchapter's current website support community engagement, but also how the websitecan be redesigned to better support community engagement. Results from the evaluation showed some functionality problems with the website andthat the way the chapter support communication and collaboration could beimproved. Based on the results, concrete design proposals were introduced to thechapter's members in order to evaluate if they could be useful for improving thewebsite. Furthermore, ideas on how to establish a strong online platform that mightcontribute to online growth for special interest communities, such as the UppsalaUniversity ACM-W Student Chapter, were given. In conclusion, the selected approach was suitable for the stage the chapter was in, andthe method described in this thesis is one tool for helping other small-scale onlinecommunities to better understand their organization and to help them narrow downtheir organization's administrative load into design solutions that ease theiradministrative tasks.

Syfte: Syftet med denna studie är att undersöka hur kundens upplevelse formas i kontexten online product community, utifrån ett multidimensionellt perspektiv på kundupplevelsen. Metod: Med bakgrund mot studiens syfte var det passande att använda en kvalitativ metod. Detta fenomen studerades genom en flerfallsstudie som den övergripande undersökningsdesignen. Semi-strukturerade intervjuer har genomförts med respondenter från tre olika online product communities. Materialet har sedan analyserat genom en abduktiv analysmetod som är inspirerad av grounded theory. Resultat & slutsats: Studien visar att kundupplevelsen för medlemmar i online product communities främst formas av den pragmatiska dimensionen, innehåll och funktionalitet är därmed centralt. Resultatet tyder även på att det finns två grupper av användare i dessa communities. Den ena gruppen är mer passiv och pragmatiskt inriktad medan den andra är mer aktiv och nöjesinriktad. Förslag till vidare forskning: Då denna studie bygger på intervjuer med medlemmar i online product communities som både kan ses som aktiva och passiva medlemmar kan det vara av intresse att i framtiden studera hur de mest aktiva medlemmar upplever att delta i denna kontext, då det är denna kärna som genererar det största innehållet. Uppsatsens bidrag: Denna studie sammanför den tidigare forskningen om kundupplevelse och senare forskning om kundupplevelse i online communities för att skapa en förklarande modell. Modellen beskriver vilka dimension som formar kundupplevelsen i denna kontext och testas sedan i tre case. Studien bidrar till en ökad förståelse för skillnaden mellan pragmatiska och mer nöjesinriktade användare. Nyckelord: Customer experience, experiental marketing, online product communities.<br>Purpose of Study: The aim of this study is to examine how the customer experience is shaped in the context online product community, based on a multi-dimensional perspective on customer experience. Method: Due to the purpose of the study qualitative methods were chosen. This phenomenon was studied by a multi-case study as the overall study design. Semi-structured interviews were conducted with respondents from three different online product communities. The material was then analyzed by an abductive method of analysis which is inspired by grounded theory. Results & conclusion: The study shows that the customer experience for members of online product communities primarily is shaped by the pragmatic dimension, content and functionality is thus essential. The results also suggest that there are two groups of users in these communities. One of the groups is more passive and pragmatic, while the other one is more active and entertainment-oriented. Suggestions for further research: Since this study is based on interviews with members of online product communities which can be seen as active and passive members it may be of interest in future research to study the most active members experiences in this context, because it is this core group that generates the largest content. Contribution of the thesis: This study brings together previous research on customer experience and recent research on customer experience in online communities to create an explanatory model. The model describes the dimensions that shape the customer experience in this context and is then tested in three cases. The study contributes to a better understanding of the difference between pragmatic and more entertainment-oriented users.

Popular websites such as Twitter, Facebook, and YouTube employ human moderators to moderate user-generated con- tent. In this thesis, we propose an automated approach to the moderation of online conversational text authored by children on the Scratch website, a drag-and-drop programming interface and online community. We develop a corpus of children's comments annotated for inappropriate material, the first of its kind. To produce the corpus of data, we introduce a comment moderation website that allows for the review and label of comments. The web-tool acts as a data-pipeline, designed to keep the machine learning models up to date with new forms of inappropriate content and to reduce the need for maintaining a blacklist of profane words. Finally, we apply natural language processing and machine learning techniques towards detecting inappropriate content from the Scratch website, achieving an F1-score of 73%.<br>by Flora Tan.<br>M.

Background There will be approximately four million people living with cancer in the United Kingdom (UK) by 2030. The National Health Service faces a major challenge meeting the support needs of this growing population, who commonly report feeling isolated and lacking social support. Approximately 45 million adults in the UK use the internet, and online communities might be a culturally relevant way to connect people affected by cancer, allowing them to support one another. However, internet communication is fraught with challenges such as misleading or untrustworthy information. We have a limited understanding of how people experience these communities and whether they can provide meaningful support for people affected by cancer. Aims To explore and understand the experiences and interactions of people affected by cancer who visit online cancer communities. Methods This was a qualitative study involving 23 people who had visited online cancer communities. Participants were affected by a range of cancers and were a combination of cancer survivors and families members. Semi-structured interviews elicited participants’ experiences, preferences and perceived consequences of using online communities. Data analysis was guided by principles of Constructivist Grounded Theory. Findings Participants used communities to ‘navigate’ the challenges they faced with cancer. This navigation produced three categories of experience in online communities. Firstly, advice from fellow community members set participants on a ‘journey to become informed’. Secondly, participants were cast into a ‘journey to recreate identity’ as they connected and formed friendships online. Thirdly, participants discovered a ‘journey through different online worlds’ to the most relevant and often hidden social communities. Conclusions This was the first qualitative in-depth study exploring how contemporary online cancer communities are used by people affected by cancer. Online communities offered multifaceted opportunities to support the cancer experience, and they may promote self-management in cancer care. These findings can inform and improve the delivery of existing online communities.

Using survey data from 75 participants in computer self-help groups, variables were identified which theoretically indicate that computer self- help groups function similarly to face-to-face self-help groups. This exploratory research provided demographic information which allows users of computer self-help groups to be more clearly described. The findings of this study indicated that computer group users perceived similar benefits of use to people in traditional self-help groups. Study participants also perceived certain benefits from computer group use not found in traditional face-to-face groups. Among these were the convenience of use, anonymity, and the benefits of writing as a way to connect to others. The findings indicated that computer groups provided a unique context in which new beliefs and ideas about problems can be constructed. The findings were interpreted to indicate that there are certain risks involved in computer group use of which mental health professionals and potential users need to be cognizant. Finally, several areas for possible future study are discussed.<br>Ph. D.

Essay #1: Reconstructing Online Behavior through Effort Minimization
Data from online interactions increasingly informs our understanding of fundamental patterns of human behavior as well as commercial and social enterprises. However, this data is often limited to traces of users' interactions with digital objects (e.g. votes, likes, shares) and does not include potentially relevant data on what people actually observe online. Estimating what users see could therefore enhance understanding and prediction in a variety of problems. We propose a method to reconstruct online behavior based on data available in many practical settings. The method infers a user's most likely browsing trajectory assuming that people minimize effort exertion in online browsing. We apply this method to data from a social news website to distinguish between items not observed by a user and those observed but not liked. This distinction allows us to obtain significant improvements in prediction and inference in comparison with multiple alternatives across a collaborative filtering and a regression validation problem.
Essay #2: Measuring Individual differences: A Big Data Approach
The amount of behavioral and attitudinal data we generate every day has grown significantly. This era of Big Data has enormous potential to help psychologists and social scientists understand human behavior. Online interactions may not always signify a deep illustration of individuals' beliefs, yet large-scale data on individuals interacting with a variety of contents on specific topics can approximate individuals' attitudes toward those topics. We propose a novel automated method to measure individuals' attitudes empirically and implicitly using their digital footprints on social media platforms. The method evaluates content orientation and individuals' attitudes on dimensions (i.e. subjects) to explain individual-content ratings in social media, optimizing a pre-defined cost function. By applying this method to data from a social news website, we observed a significant test-retest correlation and substantial agreement in inter-rater reliability testing.
Essay #3: Social Media and User Activity: An Opinion-Based Study
An increasing fraction of social communications is conducted online, where physical constraints no longer structure interactions. This has significantly widened the circle of people with whom one can interact and has increased exposure to diverse opinions. Yet individuals may act and respond differently when faced with opinions far removed from their own, and in an online community such actions could activate important mechanisms in the system that form the future of the outlet. Studying such mechanisms can help us understand the social behaviors of communities in general and individuals in particular. It can also assist social media outlets with their platform design. We propose models that capture the changes in individuals' activities in social media caused by interacting with a variety of opinions. Estimating the parameters of the models using data available from a social news website (Balatarin) as a case study, we extracted mechanisms affecting the communities on this platform. We studied the effect of these mechanisms on the future formation and the lifecycle of the platform using an agent-based simulation model. Having examined the effect of biased communities on the social media, the results imply that individuals increase their online activity as a result of interacting with contents closely aligned to their own opinion.<br>Ph.

Online social networks have become a powerful venue for political activism. In many cases large, insular online communities form that have been shown to be powerful diffusion mechanisms of both misinformation and propaganda. In some cases these groups users advocate actions or policies that could be construed as extreme along nearly any distribution of opinion, and are thus called Online Extremist Communities (OECs). Although these communities appear increasingly common, little is known about how these groups form or the methods used to influence them. The work in this thesis provides researchers a methodological framework to study these groups by answering three critical research questions: How can we detect large dynamic online activist or extremist communities? What automated tools are used to build, isolate, and influence these communities? What methods can be used to gain novel insight into large online activist or extremist communities? These group members social ties can be inferred based on the various affordances offered by OSNs for group curation. By developing heterogeneous, annotated graph representations of user behavior I can efficiently extract online activist discussion cores using an ensemble of unsupervised machine learning methods. I call this technique Ensemble Agreement Clustering. Through manual inspection, these discussion cores can then often be used as training data to detect the larger community. I present a novel supervised learning algorithm called Multiplex Vertex Classification for network bipartition on heterogeneous, annotated graphs. This methodological pipeline has also proven useful for social botnet detection, and a study of large, complex social botnets used for propaganda dissemination is provided as well. Throughout this thesis I provide Twitter case studies including communities focused on the Islamic State of Iraq and al-Sham (ISIS), the ongoing Syrian Revolution, the Euromaidan Movement in Ukraine, as well as the alt-Right.

Der volle Inhalt der QuelleAnnotation:
Social networks have proven to be an attractive avenue of investigation for researchers since humans are social creatures. Numerous literature have explored the term “social networks” from different perspectives and in diverse research fields. With the popularity of the Internet, social networking has taken on a new dimension. Online social communities therefore have become an emerging social avenue for people to communicate in today’s information age. People use online social communities to share their interests, maintain friendships, and extend their so-called circle of “friends”. Likewise, social capital, also known as human capital, is an important theory in sociology. Researchers usually utilise social capital theory when they investigate the topic relating to social networks. However, there is little literature that can provide an explicit and strong assertion in that research area due to the complexity of social capital.
This thesis therefore focuses on the issue related to providing a better understanding about the relationship between social capital and online social communities. To enhance the value within the scope of this analysis, an online survey was conducted to examine the effects of the dimensions of social capital: relational capital, structural capital, and cognitive capital, determining the intensity of using online social communities. The data were derived from a total of 350 self-selected respondents completing an online survey during the research period. The main results indicate that social capital exists in online social communities under normal circumstances.
Finally, this thesis also presents three contributions for both theory and practice in Chapter 5. The main results contribute to the understanding of connectivity in the interrelationships between individual social capital exchange within online social networks. Secondly, social trust was found to have a weak effect in influencing the intensity of individuals using online social communities. Third, the perpetual role of information sharing has an indirect influence on individual users participating in online social communities. This study also benefits online marketing consultants as marketers can not only gain consumer information easier from online social communities but also this understanding assists in designing effective communication within online social communities. The cross-sectional study, the reliability of Internet survey data, and sampling issues are the major three limitations in this research. The thesis provides a new research model and recommends that the mediating effects, privacy paradox, and social trust on online social communities should be further explored in future research.

This paper will discuss hybrid communities that connect users online with the intention of facilitating offline interaction. These electronic-to-face (e2f) communities provide social benefits to members through the unique interaction of their online and offline components. They offer members the opportunity to pursue new offline experiences, increase social capital and develop weak-tie relationships. To develop an environment that encourages members to participate online and offline, the physical design of e2f systems should include functionality that encourages a sense of community, trust and generalized reciprocity. Following a set of e2f development guidelines proposed by the author, a new e2f system called Mix It Up was created. It aims to provide the social benefits of an increased social circle by enabling users to connect online with the purpose of meeting people to organize and enjoy activity-driven offline experiences. By engaging in an online community, members can be exposed to new offline opportunities that are not currently available in their limited offline social realms. Utilizing user research, this community was evaluated in reference to suggested conceptual points of departure for the creation of e2f communities.

The aim of this study is to examine knowledge processes in online spaces. It focuses on threeparticular cases: the Bonfireside Chat podcast, the community around the computer game Europa Universalis 4, and the Supernatural fandom. By applying the frameworks of Wenger’s (1998) communities of practice and Hall’s (1980) modes of reading, it examines how these spaces and their communities engage with their respective media artifacts. It concludes thatthese processes display high levels of complexity and literacy, and that a deeper understanding of such processes is useful in developing future educational efforts, online as well as offline.

Endgeräte zum täglichen Begleiter für alle möglichen Fragen und Themen.
Jüngere Altersgruppen haben digitale Medien und mobile Endgeräte bereits fest in ihren Alltag integriert, aber auch in den älteren Generationen steigt der Anteil der Nutzer zunehmend. Durch die steigende Alltagsrelevanz und die ständige zeit- aber auch ortsunabhängige Verfügbarkeit neuer Medien verändern sich Informationsumgebungen. Eine nicht zu unterschätzende Rolle spielen dabei Online-Communities, in denen Informationen nicht nur bereitgestellt, sondern auch geteilt, bewertet und kommentiert werden können. Doch die Vielfalt möglicher Zugänge und Quellen wird auf unterschiedliche Weise genutzt. Der Zugang zu verschiedenen digitalen Quellen, die zwar nicht ausschließlich, dennoch auch durch Atersunterschiede bedingt werden.
Es wird die Frage gestellt wie sich das Informationsverhalten verschiedener Altersgruppen unter den aktuellen medialen Bedingungen darstellt.

Thesis (MSc)--Stellenbosch University, 2011<br>ENGLISH ABSTRACT: With billions of current internet users interacting through social networks, the need
has arisen to analyze the structure of these networks. Many authors have proposed
random graph models for social networks in an attempt to understand and reproduce
the dynamics that govern social network development.
This thesis proposes a random graph model that generates social networks using
a community-based approach, in which users’ affiliations to communities are explicitly
modeled and then translated into a social network. Our approach explicitly
models the tendency of communities to overlap, and also proposes a method for
determining the probability of two users being connected based on their levels of
commitment to the communities they both belong to. Previous community-based
models do not incorporate community overlap, and assume mutual members of
any community are automatically connected.
We provide a method for fitting our model to real-world social networks and demonstrate
the effectiveness of our approach in reproducing real-world social network
characteristics by investigating its fit on two data sets of current online social networks.
The results verify that our proposed model is promising: it is the first
community-based model that can accurately reproduce a variety of important social
network characteristics, namely average separation, clustering, degree distribution,
transitivity and network densification, simultaneously.<br>AFRIKAANSE OPSOMMING: Met biljoene huidige internet-gebruikers wat deesdae met behulp van aanlyn sosiale

netwerke voorgestel in ’n poging om die dinamika van die ontwikkeling van dié
netwerke beter te verstaan en te dupliseer.
In hierdie tesis word ’n nuwe toevalsgrafiekmodel vir sosiale netwerke voorgestel
wat ’n gemeenskapsgebaseerde benadering volg, deurdat gebruikers se verbintenisse
aan gemeenskappe eksplisiet gemodelleer word, en dié gemeenskapsmodel
dan in ’n sosiale netwerk omskep word. Ons metode modelleer uitdruklik die
geneigdheid van gemeenskappe om te oorvleuel, en verskaf ’n metode waardeur
die waarskynlikheid van vriendskap tussen twee gebruikers bepaal kan word, op
grond van hulle toewyding aan hulle wedersydse gemeenskappe. Vorige modelle
inkorporeer nie gemeenskapsoorvleueling nie, en aanvaar ook dat alle lede van
dieselfde gemeenskap vriende sal wees.
Ons verskaf ’n metode om ons model se parameters te pas op sosiale netwerk
datastelle en vertoon die vermoë van ons model om eienskappe van sosiale netwerke
te dupliseer. Die resultate van ons model lyk belowend: dit is die eerste gemeenskapsgebaseerde
model wat gelyktydig ’n belangrike verskeidenheid van sosiale
netwerk eienskappe, naamlik gemiddelde skeidingsafstand, samedromming, graadverdeling,

Der volle Inhalt der QuelleAnnotation:
Knowledge Management (KM) techniques and tools have been utilized by organizations from diverse sections of the Economy to achieve numerous goals such as: competitive advantage, increased innovativeness and global project management. One of the techniques of KM that has gained prominence as a very useful knowledge sharing tool is Virtual Communities of Practice. It originated from work on situated learning. In order to utilize it in a proper way it is necessary to take into account human, psychological, social and technological factors. The purpose of this research is to investigate the factors that influence participants of VCoP while they play two distinct roles: knowledge provider and knowledge receiver. This is a gap in knowledge as there is a shortage of studies that analyse these two roles in VCoPs. Most of the research in this area focus on the knowledge provider role, with few studies considering the knowledge receiver role. Both roles are present only in a few studies and even so they are not the main topics of those researches and thus these roles are not fully recognized by the authors. This leads to the research problem of how to evaluate knowledge sharing activities performed by the participants of VCoPs while they play these two distinct roles: knowledge provider and knowledge receiver. In order to address this research problem it was necessary to identify and analyse the underlying constructs and how they interact with each other. The process of identifying these constructs and their relationships was supported by existing literature and models formulated by other researchers. In 2 particular and substantial to this research were three models formulated by: Chiu et al. 2006, Lin et al 2009 and Jiacheng et al 2010. The research built relationships between the identified constructs in order to develop a research model. The constructs of the research model were operationalized into appropriate questionnaire items and interview questions. Data was collected using a validated questionnaire and interviews with key members of two VCoPs. The first study was performed with Laurea Labs in Finland and focused on knowledge intensive processes, while the second study with a group in Second Life investigated online knowledge sharing in an immersive virtual environment. In order to evaluate the research model, collected data was analysed. The tools used were Principal Components Analysis, Correlation Analysis and Multiregression Analysis. It was utilized to evaluate the conceptual model. The contribution to knowledge of this study is the identification of the critical factors influencing online knowledge sharing in virtual communities of practice, the design of conceptual model for knowledge sharing that brings together the two distinct roles participants can play (knowledge provider and knowledge receiver), operationalisation of the factors into questionnaire items and interview questions as well as empirical research in two diverse environments (research lab and immersive virtual world). 3 The most significant relationships were between Knowledge Provision and Knowledge Reception on the one hand and Online Knowledge Sharing on the other as well as Perceived Benefits and Perception of Community. The nonsignificant relationships were dropped in the final model. Qualitative findings introduced Language and Innovation Capabilities as new constructs. Besides, further findings from correlation analysis have introduced new relationships termed as propositions on the model. The implications of the research include the difference in the way the receivers as opposed to givers of knowledge in VCoPs should be motivated to engage in knowledge sharing processes. Some of the motivatiors confirmed by this study are benefits, social ties and reciprocity.

Erasmus Student Network (ESN) plays an important role in the integration process of international students who spend their study abroad period in a new country. ESN community in Kalmar in Sweden has Facebook groups for every semester which spread the hospitality through the local ESN members, also called as ‘hosts’, for the new members who can be called either ‘guests’, ‘tourists’, ‘exchange students’ or ‘freemovers’. The previous literature in tourism regarding social life online has emphasised the user-generated content on travel-related online communities on social media and ‘mobility turn’ that is an emerged topic in social sciences and has put social into travel and has thus forced researches to come up with new mobile methods to study online communities. Despite the fact that the word ‘social’ seems to be everywhere, social sustainability has been somewhat overlooked research area particularly in terms of online communities. This thesis project aims to fill this gap in the tourism literature and seeks to find out what social sustainability means in a context of online communities. Social sustainability forms the conceptual framework of the thesis and discusses the hosts and guests paradigm connecting it to online environments. The empirical material was collected by using qualitative methods including online survey distributed on ESN Kalmar Facebook groups and netnography concerning the ESN Kalmar online communities on Facebook. In addition to a theoretical contribution, the thesis project makes a methodological addition since netnography is still underutilised method among tourism scholars. These methods provided comprehensive data both from subjective and objective perspectives. The data was analysed by thematic analysis under the themes of social support, well-being and friendships, which were found to be connected to socially sustainable communities in the literature. The results found that online communities benefit from offline meetings that make the relationships between the community members stronger and thus create trust among the members. The role of the hosts and their local knowledge in the online community was proven vital in making guests to feel welcome, cared and supported during their study abroad period. However, the socially sustainable online community requires interaction and hospitality from both parties. Social sustainability of an online community can be disrupted if the community members are not cooperating and being open enough. Besides the local importance of the study in developing ESN Kalmar’s online community dynamics by emphasising the role of social sustainability, the results can be applied to discussions of internet behaviour in general. Also, the study provides help for communities where the roles between the hosts and guests are constantly “on move”.

This project examines user-generated health narratives through corpus analysis of 246 reviews posted on Midwestern Hospital’s Yelp page. Understanding how different stakeholders act and interact within online health communities models a shift in new conceptions of health, and provides evidence of health ecologies’ ability to determine patient perceptions of care. Documents produced by users in these health communities represent health narratives comprised of a user’s health experience, that user’s treatment perceptions, and the community’s perceptions of the user’s experience. Author uses corpus methods to interpret user trace data and rhetorical moves embedded in health narratives. Findings suggest that users who interact with the Yelp community produce different health narratives than less engaged users. Understanding how different stakeholders act and interact within online health communities models a shift in new conceptions of health, and provides evidence of health ecologies’ ability to determine patient perceptions of care.

Social media has had an impact on how patients experience healthcare. Through online channels, patients are sharing information and their experiences with potentially large audiences all over the world. While sharing in this way may offer immediate benefits to themselves and their readership (e.g. other patients) these unprompted, self-authored accounts of illness are also an important resource for healthcare researchers. They offer unprecedented insight into understanding patients’experience of illness. Work has been undertaken through qualitative analysis in order to explore this source of data and utilising the information expressed through these media. However, the manual nature of the analysis means that scope is limited to a small proportion of the hundreds of thousands of authors who are creating content. In our research, we aim to explore utilising text mining to support traditional qualitative analysis of this data. Text mining uses a number of processes in order to extract useful facts from text and analyse patterns within – the ultimate aim is to generate new knowledge by analysing textual data en mass. We developed QuTiP – a Text Mining framework which can enable large scale qualitative analyses of patient narratives shared over social media. In this thesis, we describe QuTiP and our application of the framework to analyse the accounts of patients living with chronic lung disease. As well as a qualitative analysis, we describe our approaches to automated information extraction, term recognition and text classification in order to automatically extract relevant information from blog post data. Within the QuTiP framework, these individual automated approaches can be brought together to support further analyses of large social media datasets.

Thesis (D.B.A.)--Boston University<br>While scholars have brought much insight into the governance of online
communities engaged in the production of goods with relatively established quality
criteria, such as open source software, they paid less attention to the governance of online communities of artistic cultural production. In artistic cultural production, due to its drive for novelty and potential resistance to institutionalized norms, it is difficult to create agreements and shared routines among participants -particularly during initial emergence when participants are new to one another and new to their form of
contributions. In this two-essay dissertation, I study arguably the largest online
community of artistic production in Turkey, Sour Dictionary, and analyze the governance
configurations during its initial emergence and ongoing growth.
The first essay describes how coherence was achieved during the birth and early
years of the Dictionary through the use of ambiguity in the two governance dimensions of
vision and rules of production. I show that in this period, ambiguity was maintained in
these dimensions not only to provide participants with the flexibility they needed for
artistic expressions, but also to bring clarity to the recognition of participants'
allegiances. The presence of a shared opposition among participants appears key to
achieving coherence in an artistic community, and for such a community, ambiguity is an
adaptive resource rather than something to eliminate as is often argued within an
economic logic.
The second essay follows a natural experiment where the founder's changing
decisions on two other governance dimensions of quality assurance and member
recruitment, along with his utilizations of IT for growth, resulted in different outcomes of coherence and popularity during the community's ongoing growth. As the founder
switched the combination of his use of IT and member recruitment method from one that
invited slow and incremental growth to one that brought sudden and massive growth, the
community faced a variety of problems in both outcomes. I show that these problems
arose as the founder responded to growth by implementing quality assurance methods
that emphasized efficiency rather than flexibility, and thus failed to a

Increasingly, people around the globe use Social Media (SM)
- e.g. Facebook, Twitter, Tumblr, Flickr, Youtube - to publish
multimedia content (posting), to share it (retweeting, reblogging
or resharing), to reinforce it or not (liking, disliking,
favoriting) and to discuss (through messages and comments)
in order to be in contact with other users and to get informed
about topics of interest. The world population is ≈ 7:4 billion
people, among them ≈ 2:3 billion (31%) are active social
media users (GlobalWeb Index data, Jan 2016). In fact, these
virtual contexts answer the human need of aggregation that
nowadays is translated into digital bonds among peers all
over the world, in addition to the traditional face-to-face
relationships. Online Social Networks (OSNs), then, provide
a space for user aggregation in groups, expressing opinions,
accessing information, contributing to public debates, and
participating in the formation of belief systems.
In this context, communities are built around different topics
of interaction and polarized sub-groups often emerge by clustering
different opinions and points of view. Such polarized
sub-groups can be tracked and monitored over time in an automatic
way and the analysis of their interactions is interesting
to shed light on the human social behavior. Even though many
studies have been devoted to understand different aspects of
the social network structure and its function, such as, community
structure (For10), information spreading (BRMA12),
information seeking (KLPM10), link prediction (LNK07), etc.,
much less work is available on analyzing online discussions,
user opinion and public debates.
In this doctoral dissertation we analyze the concept of polarization by looking at interactions among users in different Online
Social Networks. Polarization is a social process whereby a
social group is divided into sub-communities discussing different
topics and having different opinions, goals and viewpoints,
often conflicting and contrasting (Sun02; Ise86). We are interested
in studying how and to what extend it is possible to extract
information about polarized communities by automatically
processing the data about interactions created in Online Social
Networks. We present the state of the art and we propose a
novel detecting method which allows to identify polarized
groups, track them and monitor the topic evolution in the
discussion among users of an OSN over time by classifing the
keywords used in the messages exchanged. We show that
it improves the state of the art and we describe case studies
conducted particularly on Twitter (CLOP16; CGGL17).
The benefits in understanding user opinions are detailed in
the first chapters. Moreover, we use the proposed methodology
and alternatives in different application contexts: misinformation
(BCD+14a; BCD+14b; BCD+15), politics (CLOP16;
CLOP15; CLO+15), social behaviors (CALS16a; CALS16b),
and migrations (CLM+16).
A further application of opinion mining is the task of predicting
user behavior. We discuss the limitations and the
challenges related to this research area by looking at the context
of political elections and by digging into a case study of
electoral prediction. We believe that the analysis of polarized
communities is OSNs can be used to predict collective social
behavior, but major improvements in the field can be achieved
by integrating several sources of information, such as traditional
surveys, multiple Online Social Networks, demographic
data, historical information, events, cyber-physical data.
Therefore, polarization is integrated in a framework of analysis
with other dimensions (time, location) to explore social
phenomena from a social media perspective. In particular, we look at the possibility to understand European perception of
the political refugees’ crises by mining OSN data.
The concept of polarization is related to that of controversy. Controversy
describes the interaction among two or more opponent
polarized communities that discuss together, often with heated
tones. For some highly controversial topics (e.g., politics,
religion, ethics) even though users prefer to get informed
though polarized content originated in the communities they
belong to, they like to share their affiliations, believes, ideals,
convictions with external users in order to persuade them in
joining their belief system or supporting, criticizing an event,
a group, a party or a specific person. Highly polarization does
not always imply controversy and vice versa. We describe the
recent literature about controversy detection and we propose a
machine learning approach which takes into account features
related to the social network and to conversational interaction
patterns. The model is able to identify controversy in a
conversation without any feature related to the content of the
interaction. The features are deeply analyzed and the accuracy
of the model is discussed.
We finally explore two opposite situations. The first is the
formation of echo chambers, where a user gets informed and
gives opinions in a self-contained group, whose members
share a similar point of view. By analyzing communities
in Facebook which consume news from scientific pages and
from pages focused on conspiracy theories we confirm the
hypothesis of cognitive closure of the users, weakening the
idea of Social Media as a space for democratic collective intelligence.
The second is the presence of deviant communities.
Those are communities that emerge around what are usually
referred to as deviant behaviors (CM15), conducts that are commonly
considered inappropriate because they violate society’s
norms or moral standards. An example of deviant behavior
is the pornography consumption, that is the focus of our examination looking at content dissemination in Online Social
Networks. Deviant communities are commonly considered
segregated but we show that instead their content might
spread far away in the Online Social Network. We analyze
both situations with real case studies using Facebook, Flickr,
and Tumblr data.
Our work is an initial study of opinion polarization on Online
Social Networks with some in-depth analyses of specific topical
user communities. It brings novel contributions in: i)
characterizing communities through the perspective of user
polarization; ii) proposing a novel method to classify polarized
users and topic evolution over time; iii) understanding user
behavior from a social media perspective; iv) integrating polarization
with other variables (time, space) with the purpose of
analyzing a social phenomenon; v) defining controversy and
how to detect it regardless of the content; vi) describing how
people aggregate and share information in various contexts.
Different topical communities and several OSNs are described
in the dissertation, providing a general overview of the investigation
field and proposing contributions to the discussion
and solutions. Our research questions are part of a broader
research area which is called Computational Social Science.
This new discipline - which is the frame of our thesis - is a
new approach to social studies by mean of novel large-scale
computational tools, merging Social Science with Computer
Science and Machine Learning.
