Information Storage and Retrieval. Reports on Analysis, Search, and Iterative Retrieval.
Salton, Gerard
As the fourteenth report in a series describing research in automatic information storage and retrieval, this document covers work carried out on the SMART project for approximately one year (summer 1967 to summer 1968). The document is divided into four main parts: (1) SMART systems design, (2) analysis and search experiments, (3) user feedback procedures, and (4) descriptions of text editing programs. During the past year, the main effort has been devoted to experiments designed to determine the effectiveness of the automatic search and retrieval techniques incorporated into the SMART system. A comparison has thus been made between the fully automatic test processing methods used by SMART and the partly manual methods in use by the Medlars system operating at the National Library of Medicine. Attention has also been given to interactive search procedures, based on user feedback information supplied during the search process to refine the query formulations. Finally, the evaluation methodology incorporated into the SMART system has been examined, and evidence is supplied indicating that the evaluation parameters in use may be largely invariant with alterations in the query-document relevance judgments.
