SOLAR is an interactive Storage and On-Line Automatic Retrieval system which is operational at Washington State University. It can run continuously with virtually any mix of tasks in a general purpose computing environment. (22 references) (Author)

Describes an indexing technique based on overlapping word fragments as reference strings that are linked in a directed graph structure which makes possible exact match-, partial match-, and masked-partial match-retrieval and indicates search strategies for each case. Eight figures, two tables, and nine references are provided. (RBF)

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…

The Computer Assisted Reference Locator (CARL) is a computer-based information retrieval system which uses coordinate indexing. Objectives established in designing the system are: (1) simplicity of reference query and retrieval; (2) ease of system maintenance; and (3) adaptability for alternative computer systems. The source documents input into…

A library specialist and a computer specialist were asked to collaborate to solve the problem of a growing and diversified in-house, technical library in a diversified agribusiness organization. A computer program was written to: (1) generate alphabetical catalogs of collections; (2) index documents by uniterms; and (3) to retrieve documents by…

The purpose of this document is to present a final description of the original MEDLARS system as it evolved through four years of operation. The system is described as it was functioning on January 1, 1968. Among the various system elements discussed are: (1) the input subsystem, including journal selection and coverage, Medical Subject Headings…

This report describes Phase 1 of a research project with the over-all objective of exploring the applicability of automatic methods in the indexing of drug information appearing in English natural language text. Two major phases of the research have been completed: (1) development of the automatic indexing method and its implementation on the test…

This report describes the searching methods and the search program for the automatic indexing method which was developed and implemented in an earlie r phase of the project. The indexing method generates index tags automatically from English language text and creates a machine searchable file of index records for the document being processed.…

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…

The report deals with experiments in testing and evaluation of an information retrieval system within the Comparative Systems Laboratory (CSL). Section I outlines the approach and the general methodology developed in CSL, the operational design of the experiments, the construction and use of the manuals, and the general significance of the…

The ways in which digital computers can be used in information storage and retrieval are presented in the language of the nonspecialist. Indexing methods, file organization, and search strategies are discussed and a brief bibliography containing 30 IBM publications is given. The manual is intended as a first reader for those interested in the…

The trend toward on-line utilization of computers in recent years has included the emergence of computer support systems to fill the information processing needs of individuals engaged in scientific research. In this study, a new approach to document description is applied to the design of a personal information storage and retrieval system,…

Two programs addressed the development of information retrieval systems useful to a variety of users. One program was designed to examine aspects of indexing and information display. Experiments with different indexing and display systems revealed that for good relevance judgements, a display with full citation, keyboards, and abstract is…

THE FIRST-GENERATION APPROACH BY CONCEPT (ABC) STORAGE AND RETRIEVAL METHOD, A METHOD WHICH UTILIZES AS A SUBJECT APPROACH APPROPRIATE STANDARDIZED ENGLISH-LANGUAGE STATEMENTS PROCESSED AND PRINTED IN A PERMUTED INDEX FORMAT, UNDERWENT A PERFORMANCE TEST, THE PRIMARY OBJECTIVE OF WHICH WAS TO SPOT DEFICIENCIES AND TO DEVELOP A SECOND-GENERATION…

IN GENERAL, PROBLEM SOLUTIONS CAN BE FOUND ALONG A CONTINUUM OF ABSTRACTION FROM THE SPECIFIC TO THE GENERAL. THERE IS, AT ANY GIVEN POINT IN THE DEVELOPMENT OF THE SOLUTION, A MOST EFFICIENT OR OPTIMUM STRATEGY. IN INFORMATION RETRIEVAL SYSTEMS THE ULTIMATE SOLUTION IS USUALLY OBTAINED, AT A MORE SPECIFIC RATHER THAN AT A MORE ABSTRACT LEVEL. THE…
