Abstract:

This study has been conducted with Sirius International as a case company. The investigation has revolved around the weaknesses Sirius, along with the authors, have identified concerning the international collaboration and communication. It was later shown that these problems were based on a low sense of unity in the organization as a result of the lack of knowledge sharing, knowledge management, and spread of organization related information. It was decided to evaluate whether a corporate social network (CSN) could assist in these problems and if so, decide what system would be the most appro

Syftet är att belysa och analysera organisationens betydelse för studie- och yrkesvägledarnas yrkesutövning. Frågor vi ställer oss är vilka organisatoriska faktorer som påverkar studie- och yrkesvägledarnas möjligheter att utföra och påverka sitt arbete. För att besvara våra frågeställningar har vi använt en kvalitativ metod i form av intervjuer med fem studie- och yrkesvägledare verksamma i Enheten för väg

Abstract:

Centralized online social networks pose a threat to their users’ privacy as social network providers have unlimited access to users’ data. Decentralized social networks address this problem by getting rid of the provider and giving control to the users themselves, meaning that only the end-users themselves should be able to control access of other parties to their data. While there have been several proposals and advances in the development of privacy- preserving decentralized social networks, the goal of secure, efficient, and available social network in a decentralized setting has not been f

Abstract:

Recent years have seen exponential growth of social network sites (SNSs) such as Friendster, MySpace and Facebook. SNSs flatten the real-world social network by making personal information and social structure visible to users outside the ego-centric networks. They provide a new basis of trust and credibility upon the Internet and Web infrastructure for users to communicate and share information. For the vast majority of social networks, it takes only a few clicks to befriend other members. People's dynamic ever-changing real-world connections are translated to static links which, once formed,

Abstract:

This thesis is composed by three standalone papers. The first chapter is about opinion formation processes. Individuals influence each other according to the network structure. If the network is connected and satisfies other mild assumptions, the society will reach a consensus. Therefore, it is a matter of interest understanding when the network would be connected or not. Here, we develop a model where the network takes place endogenously, and agents update their opinions accordingly. We study general conditions on the initial distribution of opinions such that consensus will be reached. W

Nevertheless, according with a traditional approach competition is a standard assumption modelling financial markets.

Footlights is a platform for distributed social applications that allows users to control the sharing of private information.

Based on several socio-technical scenarios, I extract concrete technical problems to be solved and show how the existing research literature does not solve them. Ad

Most approaches to this problem make two assumptions. First, the global structure of the network is known. Second, influence probabilities between any two nodes are known beforehand, which is rarely the case in practical settings. In this the

Abstract:

Interpersonal communication with network infrastructure creates mobile and online social networks, which shorten the distance among people. It naturally leads to an important question asking for a clear and detailed description of information dissemination and diffusion process in social networks. An in-depth understanding of the question may help in various aspects,e.g., designing better communication protocols and predicting the demand of hot contents. In the thesis we focus on two concrete sub-questions. The first one is to describe the performance of mobile social networks under the pr

Abstract:

Mobile social applications have emerged in recent years. They explore social connections among mobile users in a variety of novel scenarios, including friend finding, message routing, and content sharing. However, efficiently supporting resource-demanding delay-sensitive streaming applications on the mobile platform remains a significant challenge. Research on such topics will naturally widen the usage of mobile social applications. The solutions to the challenges will provide suggestion on many related work. It is interesting and valuable to explore the system performance and users’ e

Abstract:

I denne masteroppgaven implementeres og testes to algoritmer for å finne gruppe- struktur i nettverk, nemlig Louvain-metoden og Diffusion and Propagation-metoden. Et nettverks gruppestruktur består av en naturlig inndeling av nettverkets noder i ikke-overlappende sett, der hvert sett består av noder som er tettere koblet til hver- andre, enn til resten av nettverket. De ovennevnte algoritmene er to alternativer blant mange gode iterative teknikker som har sett dagens lys i løpet av de siste 15 årene.Vi presenterer tre endringer til metodene nevnt over.

Abstract:

Opinion dynamics in a society of interacting agents may lead to consensus or to the coexistence of different opinions. The interplay between social network change and opinion formation is complex, because the agents, their social interactions and the changing social structure over time, are themselves complex. DeGroot proposed a prescriptive model for achieving consensus, where agents revise their opinions at each time step by taking a weighted average of the opinions of neighbours. This thesis contains three main contributions. First, we introduce a generalisation of the DeGroot model and exa

Abstract:

Fake news is particularly virulent in social networks, where the absence of lters helps itspread quickly. Despite the eorts put forward by the main social network companies, misinformationis still a rampant problem online. One way to limit its diusion is to expose usersto fact-checking content that debunks trending fake news stories with the hope that this willprevent them from sharing misinformation further. This intervention can be carried out by selectinga seed set of users to be exposed to this so-called mitigating content. In order to identifythe best users to select for mitigation purpos

The model is validated in a benchmark test, then used to measure sectarian influences in the ways
