Green, Rebecca – Journal of Documentation, 1995
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)

Levery, Francis – Informacion Bibliografica Educativa, 1971
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,…

Salton, Gerard – Journal of the American Society for Information Science, 1987
Briefly reviews early work in documentation and text processing, and predictions that were made about the creative role of computers in information retrieval. An attempt is made to explain why these predictions were not fulfilled and conclusions are drawn regarding the limits of computer power in text retrieval applications. (Author/CLB)

Klingbiel, Paul H. – 1977
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.…

Earl, L. L.; And Others – 1971
The development of automatic indexing, abstracting, and extracting systems is investigated. Part I describes the development of tools for making syntactic and semantic distinctions of potential use in automatic indexing and extracting. One of these tools is a program for syntactic analysis (i.e., parsing) of English, the other is a dictionary of…

Williams, John H., Jr. – 1971
The report very briefly summarizes the research performed during the contract period March 1, 1964, to February 28, 1971. The emphasis of the research was on the discovery and development of techniques for automatically indexing and classifying documents. The research was limited to statistical techniques rather than semantic or syntactic. A…

Salton, Gerard; And Others – Information Processing and Management, 1990
Summarizes various linguistic approaches proposed for document analysis in information retrieval environments. Topics discussed include syntactic analysis; use of machine-readable dictionary information; knowledge base construction; the PLNLP English Grammar (PEG) system; phrase normalization; and statistical and syntactic phrase evaluation used…

United Nations Educational, Scientific, and Cultural Organization, Paris (France). – 1973
As established within the framework of the UNISIST world science information system, the International Serials Data System (ISDS) is an international network of operational national and regional centers, jointly responsible for the creation and maintenance of computer based data banks, which contain essential information for the identification of…

Schwarz, Christoph – Journal of the American Society for Information Science, 1990
Discusses problems encountered with the syntactic analysis of free text documents in indexing. Postcoordination and precoordination of terms is discussed, an automatic indexing system call COPSY (context operator syntax) that uses natural language processing techniques is described, and future developments are explained. (60 references) (LRW)

Deerwester, Scott; And Others – Journal of the American Society for Information Science, 1990
Describes a new method for automatic indexing and retrieval called latent semantic indexing (LSI). Problems with matching query words with document words in term-based information retrieval systems are discussed, semantic structure is examined, singular value decomposition (SVD) is explained, and the mathematics underlying the SVD model is…

White, Lee J.; And Others – 1975
The major advantage of sequential classification, a technique for automatically classifying documents into previously selected categories, is that the entire document need not be processed before it is classified. This method assumes the availability of a priori categories, a selection of keywords representative of these categories, and the a…

Noel, Jacques – 1972
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…

Gibb, Forbes; Smart, Godfrey – Online Review, 1990
Describes the development of a software system, SIMPR (Structured Information Management: Processing and Retrieval), that will process documents by indexing them and classifying their subjects. Topics discussed include information storage and retrieval, file inversion techniques, modelling the user, natural language searching, automatic indexing,…
