Abstract (sommario):

Because of the complexity of the actors and the relationships between them, social networks are always represented by graphs. This structure makes it possible to analyze the effectiveness of the network for the social actors who are there. This work presents a social network analysis approach that focused on processing Facebook pages and users who react to posts to infer influential people. In our study, we are particularly interested in studying the relationships between the posts of the page, and the reactions of fans (users) towards these posts. The topics covered include data crawling, graph modeling, and exploratory analysis using statistical tools and machine learning algorithms. We seek to detect influential people in the sense that the influence of a Facebook user lies in their ability to transmit and disseminate information. Once determined, these users have an impact on business for a specific brand. The proposed exploratory analysis has shown that the network structure and its properties have important implications for the outcome of interest.

Abstract (sommario):

Online communities have become important places for users to share information. In this context, the work described in this article aims to analyze computational methods that could allow us to identify users with the highest expertise levels on a specific knowledge domain in an online community. In this study the authots extracted data from a Java discussion group from an online community - Facebook, captured some important information and represented the community as a graph. Then, the authors compared the Bow-tie structure of this community with the ones from the Web and from a forum that are described in the literature. In addition, the authors tested some graph metrics and algorithms in order to analyze if they could provide a method to find the experts in this online community. The results show that four of the tested metrics can indicate if a user is an expert or not.

Abstract (sommario):

With the emergence of large social networks, such as Facebook and Twitter, graphs with millions to billions vertices are common. Instead of processing the network within a single machine, all the applications related are intended to be done in a distributed way using a cluster of commodity machines. In this paper, we study the parallel graph partitioning problem, which is the fundamental operation for large graphs. With the help of Hadoop/MapReduce, we propose aparallel k-way partitioningapproach. Unlike the previous ones, which require enough memory to keep the whole graph data within, our novel approach breaks such limitations. Also, due to the distributed nature, it is easy to integrate our partitioning approach into existed parallel platforms. We conduct extensive experiments on real graphs and synthetic graphs. All the experimental results prove the effectiveness and efficiency of our approach.

Abstract (sommario):

Shortest path algorithm. Graphs are an example of non-linear data structure. A graph is a collection of nodes which are connected by edges. The definition of graph G = (V, E) is basically a collection of vertices and edges. Graphs can be classified on the basis of types of edges. Directed graphs have each of the edges directed which means the edges connecting the two nodes defines the way it is connected from and to. On the other side, undirected graphs have edges which have no direction. The edges of a graph have weights which are associated with it. The weight of an edge can be thought as the cost of the edge. Let’s assume there are two vertices representing two cities, then the weight of the edge between the vertices may represent the distance between the cities. Given a given graph and a particular node, we can find a path of least total weight from that node to other vertices of the graph. The total weight of the path will be the sum of the weights of the edges. Graphs can be used in real life to find the shortest path between two destinations, used in social networking sites like facebook and the world wide web where the web pages are represented by the nodes. Dijkstra’s Algorithm, Floyd – Warshall, Bellman Ford Algorithm, Johnson’s algorithm, A* search algorithm are some of the shortest path algorithms.

Abstract (sommario):

We report results from an exploratory analysis examining “last-minute” self-censorship, or content that is filtered after being written, on Facebook. We collected data from 3.9 million users over 17 days and associate self-censorship behavior with features describing users, their social graph, and the interactions between them. Our results indicate that 71% of users exhibited some level of last-minute self-censorship in the time period, and provide specific evidence supporting the theory that a user’s “perceived audience” lies at the heart of the issue: posts are censored more frequently than comments, with status updates and posts directed at groups censored most frequently of all sharing use cases investigated. Furthermore, we find that: people with more boundaries to regulate censor more; males censor more posts than females and censor even more posts with mostly male friends than do females, but censor no more comments than females; people who exercise more control over their audience censor more content; and, users with more politically and age diverse friends censor less, in general.

Abstract (sommario):

We illustrate a system that analyzes the homepage of a Facebook user or group in order to automatically detect who has discussed what and how it has been discussed. We have focused the analysis on three main actors of Italian politics. The goal is to find people who agree or disagree about given topics with the owner of the Facebook page under analysis. All public posts shared by a user are retrieved by an ad hoc built crawler. Information such as 'posts', 'comments', 'likes', are extracted from the Facebook page. Each post is classified as belonging to a set of predefined categories and its sentiment is also detected as being positive, negative or neutral. All the comments to that post are therefore analyzed and categorized together with its sentiment polarity. For each Facebook user under analysis a statistics of the topics dealt with is made, and for each category a graph is created where the concordance of sentiment is highlighted between the posts belonging to a given class and the related comments of the people interacting with the user or group under analysis. The graph can therefore be used to profile the user relationships according to sentiment classification.

Abstract (sommario):

As a relaxation of clique in graph theory, k-plex is a powerful tool for analyzing social networks and identifying cohesive structures in graphs. Recently, more and more researchers have concentrated on the algorithms for the maximum k-plex problem. Among those algorithms, a branch-and-bound algorithm proposed very recently shows a good performance on solving large sparse graphs, but does not work well on social networks. In this paper, we propose two novel vertex selection heuristic strategies for branching. The first one employs historical information of vertex reduction, and the second one is a combination of the first heuristic and the degree-based approach. Intensive experiments on Facebook benchmark show that the algorithm combining our heuristics outperforms the state-of-the-art algorithms.

Abstract (sommario):

Rapporten grundar sig på en delmängd av ett projekt som utfördes åt uppdragsgivaren SocialWorks. Projektet innefattade bland annat att arbeta mot externa webbtjänster. Genom webbtjänster kan webbaserade datorprogram kommunicera och skicka data till varandra. Då en webbtjänst nyttjas behöver utvecklaren sätta sig in i API:et för webbtjänsten. Denna rapport tar upp ett antal problem som kan uppstå vid användandet av en sådan webbtjänst och hur dessa problem kan lösas genom att skapa ett mellanlager i form av en serviceklass. Alla API-anrop ska gå genom serviceklassen och därmed behöver kodförändringar endast göras i serviceklassen ifall API:et förändras. Som ett resultat av arbetet togs en serviceklass fram som underlättar användningen av Facebooks Graph API tillsammans med PHP-ramverket Zend Framework. Genom serviceklassen behöver användaren inte sätta sig in i Facebook Graph API i detalj. Dessutom skapades en testapplikation i Zend dels för att testa serviceklassens funktionalitet och dels för att hantera så kallade testanvändare som Facebooks Graph API tillhandahåller.
This report is based on a subset of a project that was made for the company SocialWorks. The project included working with web services. Through web services, web applications are able to communicate and send data to each other. When a web service is used, the user has to study the web service API. This report addresses a number of problems that might arise from the use of such web services and how these problems can be solved by creating a service class that is used as a middle layer. All API calls will be made through the service class and thus changes in the API will only require modification of code in the service class. As a result of this report a service class was created using the PHP framework Zend Framework to facilitate the use of Facebook's Graph API. By using the service class, the user does not have to study the Facebook Graph API in detail. A test application was created to test the service class functionality and manage test users provided by the Facebook Graph API.

Dissertação para obtenção do Grau de Mestre em Engenharia Informática
Social networking sites persuade millions of users each day to adopt specific behaviors. Using the persuasive principles inherent to these sites to increase environmental awareness and reduce our ecological footprint can be challenging but certainly worthy. The DEAP project has already invested time and resources to address persuasion through different devices for a broad audience. However, there are still many obstacles when it comes to such a delicate subject as people’s routines. For many years, social factors have prevented people from adopting a way of living friendlier to our Environment. Whether it is due to lack of proper knowledge about this topic or simply because they are not willing to change, the truth is that we are eventually reaching a point where it will be too late to keep our planet as we know it. Consequently, the time has arrived when there is great need for a platform to bring existing efforts together no matter where they come from but the goal they share: change incorrect behaviors towards environmental sustainability. Towards this ambitious goal a board game was developed and integrated in Facebook capable of merging third-party applications and an important and valuable basis for future research in the field of persuasion.

Abstract (sommario):

The thesis presents an evaluation of the Facebook page of the Italian non-profit organization Oxfam Italia from November 2013 to March 2014. The research’s aim is to analyze the community which follows the organization, how this community interacts with it and how the moderators of the page communicate with its followers. The research aims also to find ways to increase Oxfam Italia’s performance on Facebook. The theoretical framework focuses on non-profit marketing and its peculiarities, Social Media Marketing and notions such as engagement and brand community. The methods used in the research consist in data mining and content analysis. Data have been gathered from Facebook Insights and through the issuing of FQL queries from the Facebook Graph API. The research found out that Oxfam has more female followers than male (62% vs 36,5%), the age range of them is 25-44 years. Oxfam’s presence, in particular, is very rooted in the region of Tuscany (where its headquarter is). Facebook followers showed a very good attitude toward the organization, even though criticisms are common, and Oxfam used its social media presence mainly to update the followers concerning ongoing activities and to urge to on-line activism. The users’ favourite engagement method was “liking” photographic contents.

This diploma thesis deals with various types of relations observable in social networks. First part contains survey of existing papers focused on social media data analysis and visualisations. This survey is followed by research of existing visualisation applications. The contribution of this thesis is a new look at relations on social networks, from the side of relationship between users who write posts on any given topic. To visualize these relations was chosen network graph. On the basis of established criteria existing instruments were evaluated and since any of them did not meet all requirements, I created new application for visualising relations. Thesis also includes a description of selection the appropriate libraries for its implementation, explanation of user interface and a summary of configuration options and customization. The end of the work contains analysis and visualisations made with newly-created tool.

Abstract (sommario):

The objective of this thesis is to develop novel techniques to find relevant people in Online Social Networks (OSN). To that end, we consider different notions of relevance, taking the point of view of the OSN providers (like Facebook) and advertisers, as well as considering the people who are trying to push new ideas and topics on the network. We go beyond people's popularity, showing that the users with a lot of followers are not necessarily the most relevant. Specifically, we develop three algorithms that allow to: (i) compute the monetary value that each user produces for OSN provider; (ii) find users that push new ideas and create trends; and (iii) a recommender system that allows advertisers (focusing in local shops, like restaurants or pubs) to find potential customers. Furthermore, we also provide useful insights about users' behavior according to their relevance and popularity, showing - among other things - that most active users are usually more relevant than the popular ones. Moreover, we show that usually very popular users arrive late to the new trends, and that there are less popular, but very active users that generate value and push new ideas in the network.

La nostra investigació va més enllà de la popularitat de les persones, mostra que els usuaris amb molts seguidors no són necessàriament els més rellevants. Específicament, desenvolupem tres algorismes que permeten: (i) calcular el valor (monetari) que cada usuari produeix per al prove ïdor del servei; (ii) trobar usuaris que proposen noves idees i creen tendències; i (iii) un sistema de recomanació que permet als anunciants (centrant-nos en botigues locals, com ara un restaurant o un pub) trobar clients potencials. Addicionalment, lliurem informació útil sobre el comportament dels usuaris segons la seva rellevància i popularitat, mostrant, entre altres coses, que els usuaris més actius solen ser més rellevants que els populars. A més a més, mostrem que normalment els usuaris molt populars arriben tard a les noves tendències, mentre que usuaris de menor popularitat, però molt actius, generen valor i fomenten noves idees a la xarxa .

Abstract (sommario):

Aujourd’hui, on parle du Web social. Facebook par exemple, porte bien la marque de son époque ; il est devenu le réseau social le plus convoité dans le monde. Toutefois, l’entreprise a été souvent critiquée en raison de sa politique qui porte atteinte à la vie privée des personnes. Par le truchement de ses modules sociaux, Facebook a le potentiel de collecter et d’utiliser des informations considérables sur les internautes à leur insu et sans leur consentement. Ce fait est malheureusement méconnu de la majorité d’entre eux. Certes, l’entreprise doit vivre économiquement et l’exploitation des renseignements personnels constitue pour elle une source de revenu. Toutefois, cette quête de subsistance ne doit pas se faire au détriment de la vie privée des gens. En dépit des outils juridiques dont le Canada dispose en matière de protection de la vie privée, des entreprises du Web à l’image de Facebook réussissent à les contourner.
Today we talk about the social Web. Facebook for example bears the mark of its time, as it becomes the most coveted social networking Web site in the world. However, the company has been criticized due to its policy that violates people's privacy. Through its social plugins, Facebook has the potential to collect considerable amounts of information about users without their knowledge and without their consent, a fact which is unknown to most of them. Certainly, the company must ensure its economic stability through these activities. However, this quest for subsistence should not be to the detriment of people's privacy. Canada has legal tools for the protection of privacy that allow users to deal with this kind of threat. However, Web companies such Facebook succeed to circumvent the law.

Abstract (sommario):

Abstract A key source of revenue for the media and entertainment domain is ad targeting: serving advertisements to a select set of visitors based on various captured visitor traits. Compared to global media companies such as Google and Facebook that aggregate data from various sources (and the privacy concerns these aggregations bring), local companies only capture a small number of (high-quality) traits and retrieve an unbalanced small amount of revenue. To increase these local publishers’ competitive advantage, they need to join forces, whilst taking the visitors’ privacy concerns into account. The EcoDaLo consortium, located in Belgium and consisting of Adlogix, Pebble Media, and Roularta Media Group as founding partners, aims to combine local publishers’ data without requiring these partners to share this data across the consortium. Usage of Semantic Web technologies enables a decentralized approach where federated querying allows local companies to combine their captured visitor traits, and better target visitors, without aggregating all data. To increase potential uptake, technical complexity to join this consortium is kept minimal, and established technology is used where possible. This solution was showcased in Belgium which provided the participating partners valuable insights and suggests future research challenges. Perspectives are to enlarge the consortium and provide measurable impact in ad targeting to local publishers.

Abstract (sommario):

A social network can be defined as a complex graph, which is a collection of nodes connected via edges. Nodes represent individual actors or people in the network, whereas edges define relationships among those actors. Most popular social networks are Facebook, Twitter, and Google+. To analyze these social networks, one needs specialized tools for analysis. This chapter presents a comparative study of such tools based on the general graph aspects as well as the social network mining aspects. While considering the general graph aspects, this chapter presents a comparative study of four social network analysis tools—NetworkX, Gephi, Pajek, and IGraph—based on the platform, execution time, graph types, algorithm complexity, input file format, and graph features. On the basis of the social network mining aspects, the chapter provides a comparative study on five specialized tools—Weka, NetMiner 4, RapidMiner, KNIME, and R—with respect to the supported mining tasks, main functionality, acceptable input formats, output formats, and platform used.

Abstract (sommario):

With the advent of online social media, it is possible to collect large information and extract information. One of the powerful roles that networks play is to bridge gap between the local and the global perspectives. For example, social network analysis could be used to offer explanations for how simple processes at the level of individual nodes and links can have a global effect. Social networks like Twitter, Facebook, LinkedIn are very large in size with millions of vertices and billions of edges. To collect meaningful information from these densely connected graphs and huge volume of data, it is important to find proper topology of the network as well as conduct analysis based on different network parameters. The main objective of this work is to study the network parameters commonly used to explain social structures. We extract data from the three real-time Facebook accounts using the Netvizz application, analyze and evaluate their network parameters on some widely recognized graph topology using Gephi, a free and open source software.

Abstract (sommario):

In this chapter, the authors apply context specific methods to formalize communicational parameters for different profile groups in a social network platform, taking Facebook as an example. Information is posted to or shared with distinct user groups. The context specific approach is used to describe informational content of exchanged data and to formalize privacy settings in a social graph. Communicational and informational parameters are specified with direction and communicational content in a context specific model. Relations are defined to model communicational and informational interactions as well as environmental factors taking influence on the profile groups. The textual representation of this approach is introduced to describe models in a text-based form.

Abstract (sommario):

People do not always use Unicode, rather, they mix multiple languages. The processing of codemixed data becomes challenging due to the linguistic complexities. The noisy text increases the complexities of language identification. The dataset used in this article contains Facebook and Twitter messages collected through Facebook graph API and twitter API. The annotated English Punjabi code mixed dataset has been trained using a pipeline Dictionary Vectorizer, N-gram approach with some features. Furthermore, classifiers used are Logistic Regression, Decision Tree Classifier and Gaussian Naïve Bayes are used to perform language identification at word level. The results show that Logistic Regression performs best with an accuracy of 86.63 with an F-1 measure of 0.88. The success of machine learning approaches depends on the quality of labeled corpora.

Abstract (sommario):

In public-private graphs, users share one public graph and have their own private graphs. A private graph consists of personal private contacts that only can be visible to its owner, e.g., hidden friend lists on Facebook and secret following on Sina Weibo. However, existing public-private analytic algorithms have not yet investigated the dense subgraph discovery of k-truss, where each edge is contained in at least k-2 triangles. This paper aims at finding k-truss efficiently in public-private graphs. The core of our solution is a novel algorithm to update k-truss with node insertions. We develop a classification-based hybrid strategy of node insertions and edge insertions to incrementally compute k-truss in public-private graphs. Extensive experiments validate the superiority of our proposed algorithms against state-of-the-art methods on real-world datasets.

Abstract (sommario):

We study a rumor spreading model where individuals are connected via a network structure. Initially, only a small subset of the individuals are spreading a rumor. Each individual who is connected to a spreader, starts spreading the rumor with some probability as a function of their trust in the spreader, quantified by the Jaccard similarity index. Furthermore, the probability that a spreader diffuses the rumor decreases over time until they fully lose their interest and stop spreading. We focus on determining the graph parameters which govern the magnitude and pace that the rumor spreads in this model. We prove that for the rumor to spread to a sizable fraction of the individuals, the network needs to enjoy ``strong'' expansion properties and most nodes should be in ``well-connected'' communities. Both of these characteristics are, arguably, present in real-world social networks up to a certain degree, shedding light on the driving force behind the extremely fast spread of rumors in social networks. Furthermore, we formulate a large range of countermeasures to cease the spread of a rumor. We introduce four fundamental criteria which a countermeasure ideally should possess. We evaluate all the proposed countermeasures by conducting experiments on real-world social networks such as Facebook and Twitter. We conclude that our novel decentralized countermeasures (which are executed by the individuals) generally outperform the previously studied centralized ones (which need to be imposed by a third entity such as the government).
