The metainformational approach represents some attempts to transform the implicit retrieval information contained in primary documents to an explicit information structure. (Author/PF)

This report summarizes the work carried out on the automatic construction of keyword classifications and their use in information retrieval. It discusses the possible characteristics of such classifications, and potential ways of using them; and describes the various approaches to classification that were considered in terms of an overall frame of…

A comparison was made of the performance in an automatic information retrieval environment of user queries and document abstracts available in natural language form in both English and French. The results obtained indicate that the automatic indexing and retrieval techniques actually used appear equally effective in handling the query and document…

The KWAC Index Generation Program was implemented at the State University of New York at Buffalo. It consists of only 252 statements for the COBOL Compiler Edition V310222 on the CDC6400 computer under the KRONOS operating system in the batch mode. The KWAC program is essentially a KWIC index generator designed for a special purpose for use in a…

Prepared as a self-instructional tool for anyone interested in indexing documents from their titles using the NEsted PHrase Indexing System (NEPHIS), this manual introduces, defines, and provides guidelines for the use of this computer-assisted indexing system. The objectives of the system are outlined, the NEPHIS computer program and input…

The Text-Pac System is capable of generating indexes and bulletins to provide a current information service without the selectivity feature. Indexes of the accumulated data base may also be used as a basis for manual retrospective searching. The manual search involves searching computer-prepared indexes from a machine readable data base produced…

An intermediate lexicon is described that employs a technique which allows, for a given subject area, the automatic translation of subject indexing from one indexing scheme into another. The lexicon was structured according to the principles of faceted classification and contained approximately 1,000 entries covering the field of library and…

Describes the use of FAMULUS, a database management system, to teach library science students at Case Western Reserve University indexing, computerized file construction, and online information retrieval. The special features of FAMULUS and their use in course instruction are outlined and evaluated. A 19-item reference list is attached. (Author/JL)

The four chapters included in this report are based on LINCS project activities undertaken since 1968, with an emphasis on indexing tools in the language sciences and related problems. Chapter one, "Indexing Tools for the Language Sciences: Methodology," discusses the development of a LINCS thesaurus and its role in the LINCS network.…

The "CumIndex" cumulates the back-of-book indexes of 96 English-language works in the field of library and information science and thus provides an in-depth index to important works in the field. The list is the result of a sequence of computer programs which edit, modify, and reorganize index entries from individual books to provide a coherent…

In a document retrieval, or other pattern matching environment where stored entities (documents) are compared with each other, or with incoming patterns (search requests), it appears that the best indexing (property) space is one where each entity lies as far away from the others as possible; that is, retrieval performance correlates inversely…

It is concluded that the techniques of automatic indexing and factor analysis are appropriate tools for curriculum analysis. However, the techniques need to be refined, and more care needs to be taken to insure that the criteria for the selection of data for the study are objective. In addition to predicting future developments, the data resulting…

This three-part report includes a brief history of the Defense Documentation Center (DDC) with a description of the collections and their accessibility; categorization of automatic indexing into three kinds with a brief description of the DDC system of machine-aided indexing; and an indication of some operational experiences with the system.…

The first part of this dissertation is a metatheoretical discussion of the needs and means of semantic analysis. This discussion includes sections on metalanguage, deep and surface structure and structural semantics, and procedures for relating the English of abstracts to a classification concordance in the same language. The second part describes…

The emphasis of this text is that the problems of information retrieval are the intellectual ones of subject analysis and description. These problems are not easily solved by technology alone, although certain inroads are being made by knowledge-based expert systems and other computer aids to indexing. Linguistic approaches are also showing…
