OWLIR: Information Retrieval On The Semantic Web

December 1, 2000 - May 1, 2003

Information in the web is presented in human understandable form .Current search engines operate on huge databases and the information retrieval techniques are keyword based indexes on Textual Data.So,not all retrieved documents answer a user's query and is limited in its automated inference capability.

We envision the future web as pages containing both text and semantic markup.We describe an approach for information retrieval over documents that consist of both free text and semantically enriched markup statements in DAML+OIL. These statements provide both structured and semi-structured information about the documents and their content. Our approach allows inferencing to be done over this information at several points: when a document is indexed, when a query is processed and when query results are evaluated. To validate our approach we have implemented a working prototype, which is based on a version of the SIRE information retrieval system and uses a semantic web inferencing system implemented using DAMLJessKB.
