The goal of the work presented here is to identify current limitations of communityportals, introduce community-driven ontology management as a new approach toontology construction and demonstrate the added value to community portals of beingcommunity-driven. The three main parts of the work are (i) the development of aframework allowing and motivating collaborative ontology construction and reuse for theend users (a person and a community), (ii) building a prototype on the basis of thisspecification, namely the People's portal, and (iii) the application of the developedinfrastructure to scenarios in semantically-enhanced community portals with theinvolvement of real users.The development of the framework for community-driven ontology management isaimed at enriching with community-supporting features the established practices forontology management in the areas of ontology development and population, storage,matching and versioning. The objective of community-driven ontology management is toprovide the means and motivations for a large number of users to "weave" and adopt theSemantic Web.
