Social Network data, represented using the FOAF Vocabulary, is some of the most prevalent data on the Semantic Web. In this work, we look particularly at trust relationships in web-based social networks and their implications for software personalization. We present a network analysis as the foundation for TidalTrust, and algorithm for inferring trust relationships, and then illustrate how the ...

We analyse the evolution of vocabularies on the Linked Open Data cloud. Based on the recent statistics of the LOD cloud, we have selected the twelve most dominant vocabularies in terms of their use in different pay-level domains. The number of versions we found for these vocabularies range between 2 to 11. While some ontologies exist for more than 10 years (e.g., FOAF) others are only online si...

Social network and data portability has recently gained a lot of interest as one of the issues for social media sites on the Web. In this paper, we will show how Semantic Web technologies and especially the FOAF and SIOC vocabularies can be used to model user information and user-generated content in a machine-readable way. Thus, we will see how data and network information can be reused among ...

Finding how the Semantic Web has evolved can help understand the status of Semantic Web community and predict the diffusion of the Semantic Web. One of the promising applications of the Semantic Web is the representation of personal profiles using Friend of a Friend (FOAF). A key characteristic of such social networks is their continual change. However, extant analyses of social networks on the...

Large scale online social networks (OSNs) such as Facebook, Twitter, LinkedIn, have become an important part of our every day life. Users are connected to multiple OSNs in which they maintain their different profiles including a lot of personal and social information. As the number of friends of a given user may grow so rapidly, it becomes impossible to manage all updates from friends’ profiles...

The contemporary Internet offers various services ranging from electronic newspapers to online social networks. To authorize themselves, users have to register to on-line services. However, most of the authentication and user management systems are incompatible with each other. Therefore the registration process must be repeated each time from the beginning, requiring multiple login-password-si...

In large online social networks, Friend Recommendation has evolved into an interesting problem. We try to find known acquaintances and new interesting friends on a Federated Social Network (FSN) , using StatusNet as our platform. FSNs are decentralized networks on the internet which can interoperate using the OStatus Suite of protocols. Friend finding on these networks is hard because we do not...
