Negotiation of inquiries in an on-line retrieval system

A prototype retrieval system with three major components for textprocessing, connectivity and decision operations, based on a distinguishable subtheory, is discussed, with a major goal to develop procedures whereby research workers can conduct an on-line dialogue via terminals with a body of scientific information.

Abstract

The focus of discussion is a prototype retrieval system with three major components for textprocessing, connectivity and decision operations. Each of these components is based on a distinguishable subtheory. Computer programs for the first two components have been written for a GE 225 computer. The complete prototype system is now being programmed for operation in a time-shared environment. It is a user-oriented system, with planned capabilities for browsing and man-machine interaction. A major goal is to develop procedures whereby research workers can conduct an on-line dialogue via terminals with a body of scientific information. Each user-submitted inquiry is a set of sentences without restriction as to vocabulary or form. The system converses with the user to obtain source-derived phrases that elaborate and refine the initial inquiry. The user is led to browse in the general area of his inquiry and to broaden or narrow it as he wishes. The system presents him with the text of documents related to his request as a further aid to request formulation. Evaluation of system performance is discussed.
