چکیده

As larger and more heterogeneous text databases become available, information retrieval research will depend on the development of powerful, eecient and exible retrieval engines. In this paper , we describe a retrieval system (IN-QUERY) that is based on a probabilis-tic retrieval model and provides support for sophisticated indexing and complex query formulation. INQUERY has been used successfully with databases containing nearly 400,000 documents.

Enhancement of Information Retrieval in Distributed Systems

The distributed system enables multiple, simultaneous connections between clients and Inquery servers. The different components of the system communicate using a local area network. Each component may reside on a different host and operates independently of the others. In this section, we describe the functionality and interaction between the clients, the connection server, and the Inquery serv...

Recent Experiments with INQUERY

Past TREC experiments by the University of Massachusetts have focused primarily on ad-hoc query creation. Substantial eeort was directed towards automatically translating TREC topics into queries, using a set of simple heuristics and query expansion. Less emphasis was placed on the routing task, although results were generally good. The Spanish experiments in TREC-3 concentrated on simple index...

TREC and Tipster Experiments with Inquery

INQUERY is a probablistic information retrieval system based upon a Bayesian inference network model. This paper describes recent improvements to the system as a result of participation in the TIPSTER project and the TREC-2 conference. Improvements include transforming forms-based speciications of information needs into complex structured queries, automatic query expansion, automatic recognitio...

Supporting Full-Text Information Retrieval with a Persistent Object Store

The inverted file index common to many full-text information retrieval systems presents unusual and challenging data management requirements. These requirements are usually met with custom data management software. Rather than build this custom software, we would prefer to use an existing database management system. Attempts to do this with traditional (e.g., relational) database management sys...
