The third annual report (covering the 18-month period from January 1969 to June 1970) of the Stanford Physics Information REtrieval System (SPIRES) project, which is developing an augmented bibliographic retrieval capability, is presented in this document. A first section describes the background of the project and its association with Project…

Presented is an exploration of parallel processing as it might be applied to three functions fundamental to information science: sorting, searching, and evaluation of a search prescription. (Author)

Updates the comparison of the ELHILL (currently ELHILL 3, formerly ELHILL 2) and STAIRS programs as they affect on-line searching of the MEDLARS citation file. (Author)

The structure of a retrospective information retrieval system that uses equifrequent word or text fragments is described, and its advantages over word oriented systems are mentioned briefly. (Author)

Introduced are information retrieval strategies based on automatic hierarchic clustering of documents. Cluster-based strategies are shown to be as effective as, and more efficient than, linear associative retrieval. (47 references) (Author/SJ)

A brief description of an efficient information retrieval system by which students, teachers, researchers, etc., may store information and data that are pertinent to their work. (AK)

Frequently it is useful to abbreviate or otherwise transform keys used for information retrieval. Given a transformation algorithm and data to be transformed, certain qualities of the algorithm relating to retrieval problems can be characterized. This paper gives some measures of effectiveness of such transformation algorithms. (11 references)…
