Katter, Robert V. – 1968
Document searching systems, such as those in libraries, are comprised of chains of components that transmit information. The components consist of mechanisms for doing classification, indexing, abstracting and cataloging of documents, and for converting users' statements of need to expressions suitable for searching the system. Improvement of the…

Saracevic, Tefko – 1968
The Comparative Systems Laboratory (CSL) proposed to deal with the problems of testing retrieval systems by examining a number of processes involved in such systems, with particular attention to the human factor. It is hoped that the results of the project will be useful in refining methodologies for experimentation with information retrieval (IR)…

Ramsey-Klee, Diane M.; Richman, Vivian – 1974
The first task of the study was to develop valid, short-cut methods of indexing the narrative content of evaluation reports that would extract the differentiating information contained in evaluative comments simply, reliably, and with as good classification accuracy as the longer initial procedure. In the second task, the original inter-indexer…

Freeman, Robert R.; Atherton, Pauline – 1968
This report describes an experimental system for remote direct access to files of computer-stored information which has been indexed by the Universal Decimal Classification (UDC). The data base for the experiment consisted of references from a single issue of Nuclear Science Abstracts. The Special Subject Edition of UDC for Nuclear Science and…
