An Infrastructure for Building Semantic Web Portals
Overview This paper presents the KMi semantic web portal infrastructure, which supports two important tasks of semantic web portals, namely metadata extraction and data querying. Central to the infrastructure are three components: an automated metadata extraction tool, ASDI, which supports the extraction of high quality metadata from heterogeneous sources, an ontology-driven question answering tool, AquaLog, which makes use of the domain specific ontology and the semantic metadata extracted by ASDI to answers questions in natural language format, and a semantic search engine, which enhances traditional text-based searching by making use of the underlying ontologies and the extracted metadata. A semantic web portal application has been built, which illustrates the usage of this infrastructure.
