Advanced Retrieval Assistance for the DGIS Gateway

Abstract

The objective of this investigation was to further develop and test advanced retrieval assistance techniques within the experimental CONIT (connector for Networked Information Transfer) testbed for possible incorporation into DGIS (DoD Gateway Information System). Significant results were achieved in three areas: (1) a partial implementation of an integrated, networkable X-Window interface, (2) implementation of the first phase of an algorithm that automatically ranks documents according to precision/relevance models, and (3) recommendations for incorporating existing advanced techniques and further design of more powerful techniques. Also developed was the design and partial implementation of an automatic search strategy narrowing selector based on user feedback or reasons for document irrelevance.
