Addresses problem of developing machine-based information system capable of indicating one document, out of a set of documents written in natural language, which shows maximal degree of homeosemy (relationship in meaning between two texts language-fragments ) toward natural language query. Linguistic aspects, information traces, trigrams,…

Controlled experiments conducted to compare effectiveness of enhanced experimental computer intermediary system, CONIT, with that of human expert intermediary search specialists indicate that experimental intermediary techniques are now capable of providing search assistance whose effectiveness at least approximates that of human intermediaries in…

Strategies, heuristics, and tradeoffs involved in online searching of bibliographic citation networks are discussed using results from field of citation analysis to describe mathematical structure of citation networks. Discussion of two studies of human information seeking behavior examines the search question and interconnectivity of the…

INFOSH is a program which allows the user to search through data in any file set up through the main INFO programs (IR 004 715) and obtain results of each search in a table format. It functions primarily to facilitate answering questions about data in a file in a way that does not involve manual scanning. It can give answers to questions dealing…

A query language which is suitable for use with a relational data base system is discussed. The language is developed as an extension of ideas found in programming languages as well as relational calculus. The development is a step towards the integration of programming languages, query languages, and data base systems. The language offers a…

A modular program is recommended for automation of the clippings file of "The Daily Texan" (student newspaper of the University of Texas at Austin). The proposed system will lead ultimately to on-line storage of the index, on-line storage of local, staff-written news stories from the previous twenty-four months, micrographic storage for backup and…

The computer-sorted word index to the Dictionary of Occupational Titles (DOT), 3rd edition, 1965 (two volumes, two supplements) was developed in 1974 by the Research and Training Center, University of Wisconsin-Stout, Menomonie, Wisconsin to facilitate use of DOT. The publication contains a 17page index section which refers the user from a…

The information retrieval demonstration and research project was designed to demonstrate the computer terminal system of information retrieval from a central computer. Specifically, the system concentrated on computer searching of the ERIC system. The demonstrations took place by locating nine terminals in volunteer districts and conducting…

This is a progress report on a project attempting to design a system of compacting text for storage appropriate to disc oriented demand searching. After noting a number of previously designed methods of compression, it offers a tentative solution which couples a dictionary of most frequent character-strings with a set of variable-length codes. The…

The computer language FOL is intended to facilitate the implementation of file organizations for information storage and retrieval systems. In many information storage and retrieval applications the designer, initially, does not know how best to organize a data base for efficient retrieval and ease of updating and modifying. It is felt that FOL…

Discusses the multilevel information system (MLIS), a retrieval system that integrates functions typical for database management systems and retrieval-oriented systems and provides several levels of data accessing, each developed for a different class of users. Twenty-two sources are cited. (FM)

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)

Describes a method for organizing, storing, and retrieving lexical data from computerized files of American Sign Language. The results of sample searches of the dictionary files are presented with a discussion of how these files and applications might be expanded. The lexicon is useful for researchers and teachers of sign languages. (Author/PJM)

Examines usage patterns of ELHILL retrieval program of National Library of Medicine's MEDLARS system. Based on sample of 6,759 searches, the study analyzes frequency of various commands, classifies messages issued by system, and investigates searcher error rates. Suggestions for redesigning program and query language are noted. Seven references…

In this study the advantages and problems involved in using Generalized Data Management Systems (GDMS) to expand the capabilities of information retrieval (IR) systems are investigated. In particular, the design of a Data Manager-1 (DM-1) based system for the Reliability Analysis Center (RAC) at Griffiss AFB, Rome, New York is studied. A design…
