Paper Abstract:	Web portals are entry points for information presentation and exchange over the Internet, used by a community of interest. Hence, they require an efficient support for communication and information sharing. Current Web technologies employed to build up these portals present serious limitations regarding information search, access, extraction, interpretation and processing. These limitations are naturally inherited by existing portals, thus hampering the communication and information sharing process between the community members. The application of Semantic Web technologies has the potential of overcoming these limitations and, therefore, these technologies can be used to evolve current Web portals into semantically enhanced Web portals. This paper presents the state of the art on the application of Semantic Web technologies to Web portals, points out the improvements achievable by the use of such technologies, and depicts requirements for future development of Semantic Web enabled Web portals. A wide coverage evaluation scheme and an evaluation criteria catalogue have been designed in order to consistently evaluate and compare existing Semantic Web portals.
