Online community sites have replaced the traditional means of keeping a community informed via libraries and publishing. At present, online communities are islands that are not interlinked. We describe different types of online communities and tools that are currently used to build and support such communities. Ontologies and Semantic Web technologies offer(More)
This paper deals with applying semantic Web technologies to the social Web can lead to a social semantic Web, creating a network of interlinked and semantically rich knowledge. One of the most visible trends on the Web is the emergence of social Web sites, which help people create and gather knowledge by simplifying user contributions via blogs, tagging and(More)
Online communities are islands of people and topics that are not interlinked. Complementary discussions exist on disparate systems but it is currently difficult to exploit the available distributed information. A Semantically Interlinked Online Community (SIOC) can enable efficient information dissemination across communities by creating an ontology that(More)
Large volumes of content (bookmarks, reviews, videos, etc.) are currently being created on the “Social Web”, i.e. on Web 2.0 community sites, nd this content is being annotated and commented upon. The ability to view an individual’s entire contribution to the Social Web would be an nteresting and valuable service, particularly important as social networks(More)
While microblogging has quickly gained a lot of interest in the Web 2.0 community, it still has not been leveraged to the Semantic Web unlike blogs and wikis. This paper describes the features, methods and architecture of a distributed Semantic Web microblogging system, as well as the implementation of an initial prototype of this concept that provides ways(More)
This paper presents a framework for the reuse and extension of existing, established vocabularies in the Semantic Web. Driven by the primary application of expert finding, we will explore the reuse of vocabularies that have attracted a considerable user community already (FOAF, SIOC, etc.) or are derived from de facto standards used in tools or industrial(More)
In this paper we describe a distributed architecture consisting of a combination of scripting tools that interact with each other in order to help to find and query decentralized RDF data. Thanks to this architecture, anyone can participate in the collaborative discovery of Semantic Web documents by simply browsing the web. This system is useful for dynamic(More)
This position paper on expert finding presents a conceptual framework for the reuse and interlinking of existing, well-established vocabularies in the Semantic Web. Such a framework can be used to connect people with people, based on joint or complementing interests (e.g. the need to develop specific new or existing skills for upcoming projects). Driven by(More)
