Free Text Retrieval Evaluation.

Abstract

The basic problems this research effort investigated were (1) the development, implementation, and evaluation of algorithms to improve recall levels in interactive, free-text retrieval using a modified version of IBM's Document Processing System (DPS); (2) the development of techniques for increasing the vocabulary capacity of DPS; and (3) unobtrusive statistical data gathering of system use, growth, and cost, through a previously developed computer program. A free-text document data based (DDB) of 46,828 bibliographic citations and abstracts from 'Psychological Abstracts' was developed. Also, two interactively accessible data bases were developed and implemented to provide free-test vocabulary control and recall improvement directly to the user. No intermediaries were used in the retrieval process. (Author)
