An Application Framework for Distributed Information Retrieval

Abstract

AbstractTo date, the adoption of content-based Distributed Information Retrieval (DIR) solutions within the domain of Digital Libraries (DL) remains rather limited. We contend that the lack of open application frameworks is a major obstacle. Not only to the rapid development and reuse of state-of-the art DIR functionality, but also to the holistic evaluation of competing DIR approaches. In this paper, we present the design and implementation of one such framework; as well as its use within the context of the DILIGENT infrastructure: a testbed of dedicated hardware, middleware and application services built explicitly for the DL domain upon the lower-level facilities of the first European GRID platform (EGEE). We conclude with a summary of future plans for its large scale deployment, testing and evaluation within this context.KeywordsDigital LibraryRound RobinApplication FrameworkReference ServiceOpen Grid Service ArchitectureThese keywords were added by machine and not by the authors.
