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 IBMs 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
