SECO: mediation services for semantic Web data

SECO (semantic collaboration), an infrastructure that lets agents uniformly access data that is potentially scattered across the Web is described. The SECO system provides mediation services that aggregate, integrate, and display RDF data obtained from the semantic Web. Using a crawler, SECO collects the RDF data available in files and uses RDF repositories as data sources. SECO applies semantic Web technologies to RDF data by combining techniques from information retrieval and semistructured databases.
