The program is a general purpose information retrieval program which can be used with a file of fixed format documents. Designed to be used by noncomputer personnel, the program provides flexibility in search requests and output format, which enable it to satisfy users' requests for information promptly and inexpensively. To insure easy adaptation…

The Cambridge Crystallographic Data Centre is concerned with the retrieval, evaluation, synthesis, and dissemination of structural data obtained by diffraction methods. This paper describes the use of a computer-based file system of both bibliographic information and numeric data to produce a compendium of interatomic distances. (10 references)…

A new, universally applicable computer program is described for the whole complex of punched card oriented literature documentation. Its characteristics are: modular construction, therefore easily adapted to user-specific problems; extremely high searching capacity; comprehensive and elastic syntax makes possible new unconventional methods of…

WISE is an on-line, interactive information retrieval system designed to operate on key-word-oriented data bases. The WISE user searches a data base by entering and combining key-words that are appropriate to the data base and the subject matter. The user also enters certain command statements to enhance the results of the search and to control…

WISE is an on-line interactive information retrieval system designed to operate on keyword oriented data bases. The system was designed particularly with bibliographic data bases in mind, but it is potentially useful for any keyword oriented data base. The WISE user searches a data base by entering and combining keywords that are appropriate to…

GANDALF (General Alpha Numeric Direct Access Library Facility) is an information retrieval system designed and implemented at the University of New Mexico for the purposes of retrieving abstracts from large abstract data bases, such as the ERIC system. Previous batch-process information retrieval systems for use with the ERIC data base have been…

TRIAL is an information processing system that will perform editing, indexing, and retrieval of textual and certain types of numeric information. The system allows for: (1) the creation and maintenance of a master file, (2) indexing on words designated as 'key' words or, alternatively, on every word in the text, excluding those common terms that…

This report describes for the potential user a set of procedures for processing textual materials on-line. In this preliminary model an information analyst can scan through messages, reports, and other documents on a display scope and select relevant facts, which are processed linguistically and then stored in the computer in the form of logical…

Information centers exist to provide information from machine-readable data bases to users in industry, universities and other organizations. The computer Search Center of the IIT Research Institute was designed with a number of variables and uncertainties before it. In this paper, the author discusses how the Center was designed to enable it to…

A substructure search screening system based on bond-centered fragements was evaluated using 108 queries derived from user SDI profiles. (Author/JB)

A major problem in the design of screening systems for substructure searches of chemical structure files is the development of a methodology for selection of an optimal set of structural characteristics to act as screens. Distributions of several structural characteristics of the Chemical Abstracts Service Registry System are summarized. (13…

QUEST is an interactive conversational Programming System (CPS) that was developed to serve as a conversational interface between a searcher of the Educational Resources Information Center (ERIC) files and the North Carolina Science and Technology Research Center's Inverted File Search Program (STRC-IVS). This paper describes QUEST: its costs,…

The Tarrytown Technical Information Center at General Foods produces report style searches by using upgraded equipment which allows search strategies to be stored and edited offline, thus reducing costs for both online searching and for the searcher's time. A computer program for eliminating duplicate bibliographic citations is included. (RBF)

Objectives of this project were to develop and test a method for automatically processing the text of abstracts for a document retrieval system. The test corpus consisted of 768 abstracts from the metallurgical section of Chemical Abstracts (CA). The system, based on a subject indexing rational, had two components: (1) a stored dictionary of words…

This report describes various aspects of generalized or task-oriented programing systems and in particular, how their features can be adapted for retrieval from (typical) information center and library data bases such as those described in a previous report (LI 000 498). It is not meant to be comprehensive in the sense that all such systems are…
