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)

A comparative evaluation of results in terms of recall and precision from queries submitted to systems with automatic and manual subject indexing. Differences were attributed to query formulation. The effectiveness of automatic indexing was found equivalent to manual indexing. (Author/KP)

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

The technique described enables an on line computer based information retrieval system to aid indexers by selecting possible indexing terms to be assigned to a new document entering the system. The economic aspect of implementing the technique in a working information retrieval system is considered. (16 references) (Author/MM)

This paper describes an application of Keyword-in-Context/Keyword-Out-of-Context programs to index masters' theses and doctoral dissertations at the Catholic University of America. (Author/MF)

The last in a series of five papers, the author concludes that only three characteristics of indexing seem to be capable of being compared quantitatively. These are breadth of vocabulary, depth of indexing, and the use of see and see also references. (AB)

Presents a selective review of works in 1981 concerned with subject access to information sources, with specific discussions devoted to general and theoretical works, vocabulary management, classification schemes, subject headings, indexing, and automatic indexing and classification. A 110-item bibliography is included. (JL)

Provides an overview of current newspaper indexing methods, including discussion of those indexes produced by commercial firms, public libraries, newspapers themselves, and news data banks. (FM)

A probabilistic model of keyword indexing is outlined, and some of the consequences of the model are examined. An algorithm defining a measure of indexability is developed--a measure intended to reflect the relative significance of words in documents. (Author)

A survey of automatic indexing systems and experiments has been conducted by the Research Information Center and Advisory Service on Information Processing, Information Technology Division, Institute for Applied Technology, National Bureau of Standards. Consideration is first given to indexes compiled by or with the aid of machines, including…

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…

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…

Describes a method of selecting index terms directly from a word frequency list, an idea originally suggested by Goffman. Results of the analysis of word frequencies of two articles seem to indicate that the automated selection of index terms from a frequency list holds some promise for automatic indexing. (Author/MBR)

Index names for chemical substances have been significantly revised by Chemical Abstracts Service beginning with vol. 76. Content and rationale for these changes are described. (JB)

An experiment was conducted to design a corporate author index to a large bibliographic file. The nature of corporate entries necessitates a different search key construction from that of personal names or titles. Derivation of a search key to select distinct corporate entry records is discussed. (7 references) (Author)
