Heaps, H. S.; Schuegraf, E. J. – Information Storage and Retrieval, 1975
Describes the advantages of using variable length equifrequent fragments as the language elements for compression coding of large data bases. (Author)
Descriptors: Algorithms, Databases, Information Storage, Information Systems
Chai, D. T. – Information Storage and Retrieval, 1973
The problems of using English for information retrival are delineated. The querying capability of a keyword dialog system is illustrated with actual computer output. Major advantages of this approach are: reduced ambiguity in requests, users may think in smaller functional units, and users may edit previous requests. (7 references) (Author/SJ)

Jonkers, H. Louis – Information Storage and Retrieval, 1973
A design method for information retrieval systems, based on a modelling technique, and derived from the general objectives and tasks set for the system is described. (12 references) (SJ)

A high degree of constancy has been found in the microstructure of titles of samples of the INSPEC data base taken over a three-year period. Character and digram frequencies are relatively stable, while variable-length character-strings characterizing samples separated by three years in time show close similarities.

The paper describes TSAR, a current awareness or SDI system which has been developed for processing MARC records in general, but is particularly concerned with the INSPEC service. Some statistics on the frequency of occurrence of words and comments on data compression conclude the paper. (7 references) (Author/SJ)

Irvine, J. J. – Information Storage and Retrieval, 1973
This paper describes a technical document center providing remote-terminal retrospective search capability and shows its evolution from the traditional catalog card operation. (2 references) (Author)
