To index at the Defense Documentation Center (DDC), an automated system must choose single words or phrases rapidly and economically. Automation of DDC's indexing has been machine-aided from its inception. A machine-aided indexing system is described that indexes one million words of text per hour of CPU time.

The report is concerned with the implementation of an on-line information storage and retrieval system for the Rome Air Development Center. This system is to incorporate techniques of automatic document classification for a large document collection in an interactive environment. Following a review of the system design, the implementation of the…

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…

Investigates the feasibility of using a distance measure for automatic sequential document classification. This property of the distance measure is used to design a sequential classification algorithm which classifies key words and analyzes them separately in order to assign primary and secondary classes to a document.

The Latent Semantic Indexing and MatchPlus systems examine similar contexts in which words appear and create representational models that capture the similarity of meaning of terms and then use the representation for retrieval. Text Retrieval Conference experiments using these systems demonstrate the computational feasibility of using…

Feasibility study findings indicate that a potential reduction in drudgery for the scholar may be obtained through a combination of heretofore divergent solutions to the increasingly critical problem of how researchers will interface with computers for an efficient and effective review of the literature. Presently existing computer software…

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)

This investigation matches the emerging techniques in computerized natural language processing against emerging needs for such techniques in the information field to evaluate and extend such techniques for future applications and to establish a basis and direction for further research toward these goals. An overview describes developments in the…

Part of a larger effort in creating a computer-based European Documentation and Information System for Education (EUDISED), the present document is the report of the Working Party on formats and standards. It presents draft recommendations on general system standards: transmission standards (interchange format, magnetic tape standards, tape labels…

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 three papers presented at this assembly focused on communications technology and the information industry, organization of information, and development of the Machine-Readable Cataloging (MARC) system. "The Communications Revolution: America's Third Century Challenge" examines the growth of society from a pre- to a post-industrial…

A project to develop an automated index of information about existing computerized instruction in the health sciences is reported and described. Methods of obtaining and indexing materials for the catalog are detailed. Entry and recovery techniques and selection of descriptors are described. Results to date show that the data base contains…

Part of a larger effort in creating a computer-based European Documentation and Information System for Education (EUDISED), the present document contains four papers proposing specifications for procedures and formats to be incorporated in the documentation standards of EUSIDED. The first is a "Preliminary Study for the Design of a Coding…

The 15-year history of the development of library automation is traced, and four major obstacles which had to be overcome are identified: the lack of funds for development, programing, and testing; the need for a common data base; the need for cooperative arrangements among institutions; and the need for widely-available on-line processing. Seven…
