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 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)

It is the purpose of this handbook to provide managers and their assistants with guidelines for determining where new information processing systems (dissemination, storage and retrieval) might profitably be employed in Government offices and with criteria for selecting the right methods and equipment. While the main objective is to encourage…

Discusses the role of certain types of classifications in a modern automated environment. (Author/PF)

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 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…

Describes MANIS, an information system for retrieval of interdisciplinary information in management, which maintains traditional classification but allows the user to combine terms of his choice, where choice is restricted to terms belonging to the systems of traditional classification. (CWM)

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)

The SALOMON project automatically summarizes Belgian criminal cases to improve access to existing and future court decisions. This article gives background information about the texts of the cases and describes the output, design models, and architecture of the SALOMON system. Evaluation of 700 criminal cases demonstrates that the algorithms have…

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)

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.…

A model which relates the access control and indexing functions. The model is based on concept protection which allows a practically unbounded number of levels (subsets) of protection without requiring a fixed hierarchy among the levels. This protection is offered independently for each of the user operations allowed. (Author)

Describes XMARC, a set of computer programs which provides students with a simplified means of writing programs for the automatic indexing of an experimental collection of MARC records. (Author/FM)

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…
