Many virtual communities have surfaced and come together on the World Wide Web. Web-based community portals serve as a one-stop place for all information needs serving a group of users that have common interests. As organisations become highly dynamic and the people that join them become more geographically dispersed, the need for improved ways to share and distribute data and information amongst the community or organisation members has increased dramatically.
These communities of practice (CoPs) or knowledge collaborators often share similar backgrounds, work activities and information, i.e., they share similar ontology items speaking in terms of the Semantic Web (Berners-Lee, Hendler, & Lassila, 2001). Semantic community portals can make use of Semantic Web technology and these shared community terms to create connections between people and people and also between people and the information that they produce. Frequent communal use of Semantic Web-based portals and other ontologically-annotated environments affirm the ever growing importance of the topic.
