- Abstract
- Integrates structured data and text using the unchanged, standard relational model to implement an information retrieval system. Uses a prototype to verify it, and then investigates the performance of a parallel relational database system for this application. Also tests the effect of query reduction on accuracy and finds that queries can be reduced prior to their implementation without incurring a significant loss in precision/recall. This reduction also serves to improve run-time performance. Compares the results to a special purpose information retrieval system. The relational model offers scalable performance and includes the ability to integrate structured data and text in a portable fashion
