Presented is an exploration of parallel processing as it might be applied to three functions fundamental to information science: sorting, searching, and evaluation of a search prescription. (Author)

Results of an attempt to extend the capabilities of a previously-existing automatic abstracting system by adding a modification procedure designed to make system-produced abstracts more acceptable to readers are reported. A rationale for this modification phase is presented, along with several modification rules and methods for improving…

Experiments with two distinct collections, using three levels of indexing exhaustively for both documents and requests, show that substantially the same performance is obtained for very different levels of document indexing, if suitable choices are made of request level. (6 references) (Author)

Because they look to the computer for automatic processing of verbal information, linguists have allied themselves with mathematicians. (10 references) (Author)

Presents the results of an investigation into information structures in natural language science texts. (Author)

This research shows that by submitting samples of the client's recent professional reading material to automatic text analysis, Selective Dissemination of Information (SDI) profiles can be prepared that result in significantly higher initial recall scores than do those prepared by conventional techniques; relevance scores are not significantly…

The need to provide reliable information on the properties of substances and materials has led to the proposed establishment of a numerical data system. The problems this poses, the most urgent of which is that of developing basic methodological principles underlying the data system processes, are discussed. (32 references) (Author/KE)

Because of an absence of theory, rules and conventions for thesaurus construction and maintenance, an investigation of how thesauri are actually updated was conducted. Two concepts crucial to any theoretical foundation of thesauri and two techniques for systematic updating of a thesaurus are presented for consideration. (46 references) (Author/KE)

A rationale for constructing a metalanguage to analyze natural language texts is provided in the context of a long-range program of research, and illustrated by reference to an existing Computer-Assisted Language Analysis System (CALAS). (JB)

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)

The use of extracts as a substitute for abstracts in information services is explored via a survey and a literature review and guidelines for selecting extract material from documents are given. (30 references) (NH)

An operational, comprehensive, economical method for updating and correcting entries in a computerized bibliographic system is presented. The technique was developed in connection with the East African Agricultural Bibliographic Project at West Virginia University. Data modification operations are discussed as well as the limitations of the method…

An experiment using a computer to assign content designators to unedited machine readable bibliographic data to create MARC records is described. (Author)

This paper defines the relationship between linguistics and information science in terms of a common interest in natural language. The concept of a natural language information system is introduced as a framework for reviewing automated language processing efforts by computational linguists and information scientists.

The direct-chaining technique of hash coding is generalized in a manner that is useful for storing records on the basis of non-unique search keys. Two hash functions are used, a process implying a tree structure. Two models, one involving unique and the other non-unique keys, are presented. (7 references) (Author/KE)
