Purpose: The paper aims to assess the utility of non-agriculture-specific information systems, databases, and respective controlled vocabularies (thesauri) in organising and retrieving agricultural information. The purpose is to identify thesaurus-linked tree structures, controlled subject headings/terms (heading words, descriptors), and principal…

In this paper, we propose a syntax-based text retrieval system for on-line language learning and use a fast regular expression search engine as its main component. Regular expression searches provide more scalable querying and search results than keyword-based searches. However, without a well-designed index scheme, the execution time of regular…

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)

An indexing system for chemistry and technology of macromolecular substances is sketched out, whose characteristics are convenience of use and low cost. The selection mechanism consists of a set of optical coincidence cards. The selection is a result of 15 years experience in the German Plastics Institute. (13 references) (Author)

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)

A model of word occurrences in documents is presented in the context of a model information system. (Author/PF)

Some problems arising in the combination of discipline-oriented retrieval systems for the purpose of constructing a specialized retrieval system for a multidisciplinary topic are considered. A compromise solution involving an augmented combined index is suggested. (4 references) (Author/NH)

The first of a series of five papers whose aim is to find a rational basis for indexing and some means to evaluate it. (Author)

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.…
