A brief history of bibliographic activities of the U.S. Geological Survey, including development of a computerized publishing system is given. Also described is the design of the bibliographic search system, application of the Generalized Information Processing System (GIPSY) to storage and retrieval of earth sciences literature, and preliminary…

Indicates how a college, with an IBM 1130 computer, can facilitate information storage and retrieval by using magnetic disc storage in conjunction with ACT Program, 80-column Hollerith-type card format especially designed for the college. (JF)

The Clinical Documentation Section of Schering Corporation's Medical Information Center has developed an automated document storage and retrieval system capable of generating indexes to all documents in the system, summaries, and reports for management by computer. (MF)

Presents a model information retrieval system for the case when a hierarchic set of descriptors is defined. (Author/PF)

REQUIREMENTS OF A PILOT INFORMATION SERVICE FOR EDUCATIONAL RESEARCH WERE INVESTIGATED BY ISOLATING THE CHARACTERISTICS OF DOCUMENTS JUDGED RELEVANT BY QUESTIONERS (USERS). IN ADDITION, RETRIEVAL STRATEGIES WERE COMPARED ON THE BASIS OF THE RELEVANCE AND RECALL FACTORS FOR EACH STRATEGY. THE FOLLOWING CONCLUSIONS WERE REACHED--(1) IN PROGRAMING…

Several algorithms were investigated which would allow a user to interact with an automatic document retrieval system by requesting relevance judgments on selected sets of documents. Two viewpoints were taken in evaluation. One measured the movement of queries toward the optimum query as defined by Rocchio; the other measured the retrieval…

A THESAURUS OF EDUCATIONAL TERMS WAS PRODUCED TO PROVIDE A TERMINOLOGY BASE WHICH WOULD BE AMENABLE TO RAPID AND EASY MODIFICATION AND UPDATING. THE PRIMARY SOURCE OF TERMS WAS A SEMANTIC CODE DICTIONARY, PREVIOUSLY CREATED DURING THE INDEXING OF SOME 6,500 EDUCATIONAL RESEARCH DOCUMENTS. A FACETED STRUCTURE WAS CREATED. THE DISPLAY CONSISTED OF…

Extensions are required to the currently operational INGRES data base system for it to manage a data base distributed over multiple machines in a computer network running the UNIX operating system. Three possible user views include: (1) each relation in a unique machine, (2) a user interaction with the data base which can only span relations at a…

Four advantages of storing and retrieving geometric figures and chromosome images through the use of shape-oriented similarity measures are presented. (Author)

An explanation of the regulation of forms, reports, correspondence, files, and records centers as required for the systematic control of active and inactive records. (JB)

Detailed examples illustrate one of the possible applications for using the computer punch card for information retrieval in qualitative historical research, suggesting a time-saving method of organization for research data. (SM)

The use of a structured system of storing information, particularly relational indexing, can lead to situations in which items would not be retrieved due to technicalities of the system. To overcome such problems a study was made of condensations with the aim of providing a series of rules to apply. (4 references) (Author/SJ)

A review is given of doubly-chained trees for information retrieval. It is shown that the chaining steps may be of different cost depending upon whether the step is vertical or horizontal. The problem of constructing an optimal retrieval tree is formulated mathematically and a solution procedure given. (5 references) (Author/KE)

The adaptability of the theory of integrative levels to a generalised classification scheme is questioned in that its hypotheses have not been adequately developed and confirmed. It is suggested that not enough cognisance has been taken of twentieth century relativistic thinking in which space-time is treated as a continuum. (14 references)…
