In this paper we give an overview of the Foafing the Music system. The system uses the Friend of a Friend (FOAF) and Rich Site Summary (RSS) vocabularies for recommending music to a user, depending on her musical tastes. Music information (new album releases, related artists’ news and available audio) is gathered from thousands of RSS feeds —an XML format for syndicating Web content. On the oth...

With the currently growing interest in the Semantic Web, metadata is becoming to play an important role in the Web. As one of forthcoming metadata standards for the Semantic Web, FOAF defines an RDF vocabulary for expressing metadata about people and the relation between people. In this paper we propose the novel keyword extraction method to extract FOAF metadata from the Web. The proposed meth...

One of the core goals of the Semantic Web is to store data in distributed locations, and use ontologies and reasoning to aggregate it. Social networking is a large movement on the web, and social networking data using the Friend of a Friend (FOAF) vocabulary makes up a significant portion of all data on the Semantic Web. Many traditional webbased social networks share their members’ information...

Comic strips can be used as a style of visualization on a human–computer interface because they can represent a wide variety of affairs with contexts or time series. This paper describes two systems for sharing personal context as comic strips: ComicDiary and Comic-FOAF-Viewer. Both the systems depict personal experiences or profiles including personal relationships in their comic strips and hy...

In this work we report about the automatic creation of dynamic user profiles that combine personal data from diverse social networks with context information recorded by IYOUIT, a mobile community service in the field of context awareness. Data mining algorithms are applied to learn about users and their preferences over time. Rich, semantically annotated Friend of a Friend (FOAF) profiles are ...

In this paper, we describe a structural analysis of social networks on the Semantic Web. We performed a comprehensive analysis of graph-theoretical properties of online social networks based on the Friend-ofa-Friend (FOAF) ontology. Of particular interest were properties related to the small-world phenomenon. More than 1.6 million FOAF documents collected on the Semantic Web were analyzed in de...

Diese Arbeit befasst sich mit der Konzeption und der Entwicklung eines mobilen Social Semantic Web Clients. Er ist auf internetfähigen Handys, Internettablets, Netbooks und weiteren Geräten mit dem Android-System einsetzbar. Der Client ermöglicht es, das Onlineprofil des Benutzers zu importieren und zu bearbeiten. Er importiert ebenfalls die darin referenzierten Profile von Bekannten von den ve...

FOAF files are often used for publishing simple information about persons and about their community. Our proposal is to extend the user’s FOAF files with automatically generated user profiles, which are based on a histogram of the user’s interest and which are also semantically enriched using the GrowBag approach [1]. The main assumption is that such user profiles can provide good hints about u...

Social networks are widely accepted application of Semantic Web technologies and are also interesting for general public. Nowadays there is a lack of quality user-friendly browser which could express meaning of the metadata stored in the most of FOAF profiles and present this knowledge in human-understandable form. The aim of the article is to inform about development of the AFE (Advanced FOAF ...
