"Building faceted metadata retrieval applications using RDF"

9/12/2003: 10:30am - 12:00pm
11th Floor Large Conference Room

Abstract: Faceted metadata retrieval is an approach to providing users access to large collections of semi-structured data and content that promises an improvement in usability over that available using more traditional methods [Hearst 2001]. Seamark Server is an application that generates a faceted metadata retrieval interface from instance metadata, ontologies, and controlled vocabularies expressed in RDF and RDF Schema. This talk will describe the storage, query and inference mechanisms that Seamark uses to efficiently support faceted metadata retrieval over large collections of objects, the XRBR query language used to provide a stateless protocol for faceted metadata retrieval Web services, lessons learned through a series of pilot and commercial applications, and future directions.
