Understanding of the communications process centers generally around the conduct of the process rather than the content, and particularly the establishment of communication channels. The communications model has three generally agreed upon components: source, channel, and destination. Destination may include questions about the nature of things,…

THE MAIN OBJECTIVES OF THE ANALYSES INCLUDE--(1) A RESEARCH STUDY OF TECHNIQUES FOR THE EVALUATION OF ASSOCIATIVE AND COORDINATE MESSAGE RETRIEVAL METHODS. (2) THE PREPARATION AND ANALYSIS OF MACHINE-READABLE TEST CORPORA SUITABLE FOR EXPERIMENTS WITH ASSOCIATIVE MESSAGE RETRIEVAL METHODS. THESE CORPORA CONSIST OF APPROXIMATELY 10,000 MESSAGES AND…

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…

Examples are given of the kinds of machine-readable data bases that should be developed in order to extend attempts at universal bibliographical control into neglected areas, the results of which can be used by researchers in the humanities, specifically those using books printed before 1801. The principles of bibliographical description,…

Designed to be of assistance to the new ERIC user, this glossary provides brief definitions of more than 60 terms associated with the ERIC data base and the search process. These include titles of indexes, agencies, and acronyms peculiar to ERIC as well as terms used to describe computer search strategy. A directory of ERIC network…

THIS APPENDIX TO THE FINAL REPORT OF THE AIP/UDC PROJECT (LI 000 583) INCLUDES THE COMPLETE, MERGED SET OF UDC SCHEDULES ACCUMULATED BY THE AIP/UDC PROJECT FROM 1965-1967. PART 1 OF THE FILE CONTAINS 110,759 RECORDS. EACH RECORD INCLUDES THE UDC NUMBER, A CODE WHICH REPRESENTS THE SOURCE OF THE RECORD, AND THE ENGLISH LANGUAGE EQUIVALENT OF THE…

This set of information sheets on the Educational Resources Information Center (ERIC) is designed for use by persons responsible for instructing potential ERIC users and contributors. Adaptable for reproduction as overhead projection transparencies, the sheets are classified in two dimensions to provide for greater flexibility. The set of 50…

This primer is intended to acquaint public, academic and special librarians with the current state of the art in microform technology. Brief discussion is given of the advantages and disadvantages, economics, reading and printing capabilities, continuous and unitized microforms and the various analogies of microfilm technology to other technology.…

The development and testing of the Browsing On-line With Selective Retrieval (BROWSER) text retrieval system allowing a natural language query statement and providing on-line browsing capabilities through an IBM 2260 display terminal is described. The prototype system contains data bases of 25,000 German language patent abstracts, 9,000 English…

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…

The core of this software package for information retrieval is a new language called Information Search Language (ISL). It was developed to facilitate the manipulation of real character strings in an interactive environment. The discussion of the ISL language and some of its characteristics is followed by a description of two application programs,…

A summary analysis is made of problems encountered by retrieval staffs in three states during the initial year of the Pilot State Project in Information Dissemination. Problems discussed are: (1) Computer Related; (2) Furnishing the client with complete copy; (3) Record keeping and Filing; and (4) Staffing. Recommendations resulting from the…

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)
