A new testing process is described. The design of the test procedure is covered in detail, and the several language processing features incorporated into the SMART system are individually evaluated. (20 references) (Author)

Progress is reported at the 1,000,000 word level on the development of a partial syntatic analysis technique for indexing text. A new indexing subroutine for hyphens is provided. New grammars written and programmed for Machine Aided Indexing (MAI) are discussed. (ED 069 290 is a related document) (Author)

Some of the literature concerning citation indexing is discussed with emphasis on research projects. (52 references) (Author/NH)

Outlines the concepts and facilities of SLC-II, a basic support for R&D in automatic documentation and language translation, and gives a detailed description of its use in automatic indexing. The design and running of a full-scale pilot project is described, with a parallel experiment in the effectiveness of "thesaurus enrichment" by semiautomatic…

This review of the Keyword-in-Context (KWIC) indexing considers its inception by Luhn, its original format and purpose, various applications and uses of the basic KWIC concept, its advantages and disadvantages, and evaluations of its effectiveness. (30 references) (Author/NH)

It is shown that this new automatic indexing technique can be applied with the same effectiveness shown earlier for indexes derived from words in titles or title-like phrases; the basic difference being that linear notation symbols rather than words are used as the indexing units.

Presents criteria for an effective syntagmatic relator system and describes how conceptual syntagmatic relationships are expressed in natural language, commenting on the adequacy of such expressions for document retrieval systems. Only one type of expression, a gestalt structure, represented as a frame, conforms to the criteria. (Author/JKP)

Documentation centers are needed to handle the vast amount of scientific and technical information currently being issued. Such centers should be concerned both with handling inquiries in a particular field and with producing a general catalog of current information. Automatic analysis of texts by computers will be the best way to handle material,…

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 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…

There are six major studies of the effect of indexing depth on retrieval performance. They differ in purpose, methodology, measures, indexing language, field of study, and data base--nevertheless, all have found depth of indexing to have the same effect upon information retrieval.

Progress is reported on the development of a partial syntactic analysis technique for indexing text. Although over 500,000 words of text have been indexed, this report is limited to the analysis of results at the 115,000 word level. There is the expectation that the error rate of commission, the selection of grammatically incorrect word sequences,…

The objectives of this study were: (1) to create a set of computer programs capable of practical associative processing of NASA's growing document collection, (2) to process the collection with these programs, exhibiting the achievement of a capability to perform associative search of the collection, and (3) to study the use of statistical…

Designed for use with a computer-produced subject index, PRECIS assigns clerical procedures in subject heading work to computer programs. The subject headings represent a unique combination of several different characteristics, permitting several coextensive forms of a subject name for each work. Final choice amongst alternatives is made by the…

A uniterm keyword system is explained which is thought to be suitable for small information centers operated by a staff of one or two. (3 references) (Author)
