This article attempts to offer an overview of the current changes that are being experienced in the management of audio-visual documentation and those that can be forecast in the future as a result of the migration from analogue to digital information. For this purpose the documentary chain will be used as a basis to analyse individually the tasks…

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 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)

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 main purpose of the experiment was to answer the question whether broad or narrow terms function most effectively in the retrieval of relevant documents. The answer depends on what the user of the retrieval system wants, his wants being expressed in terms of stated precision-recall preference, or by the exact number of relevant documents he…

The index term input to three information retrieval systems has been analyzed in detail in order to form the input to a completely computerized simulation of an information retrieval system. The paper reports that, with certain reservations, index terms conform in general with the Bradford distribution. (Author)

The retrieval decision problem is considered from the viewpoint of a decision theory approach. A threshold rule based on earlier rules for indexing decisions is considered and analyzed for retrieval decisions as a measure of retrieval performance. The threshold rule is seen as a good descriptive design measure of what a reasonable retrieval system…

Twelve papers written by fifteen authors from nine countries comprise this collection which embraces many of the crucial problems facing modern information science and scientific information activities, ranging from information needs of scientists and specialists to the specific aspects of computerization of various information processes. The…

Of the problems discussed, those posing the greatest obstacle for the full utilization of microform systems are: (1) the problem of identifying the material on microforms when it is associated with key words in computerized digitalized systems; (2) the problem of copyright in converting collections of material into microform stores; and (3) the…

The aim of the conference was to hold a working discussion on problems essential to the building of thesauri, a uniform comprehension of which would make it possible to build them in a manner ensuring easier communication and exchange of information between information systems covering different ranges of subject matter, and using different…

Reviews characteristics and efficiency of types of information retrieval systems, and concludes that for selective dissemination of information from computer tapes keyword indexing is less efficient than enumerative hierarchical systems which require single hit searching. (AL)

With a view to improving information systems and services in Eastern, Central, and Southern Africa, this Information Systems Workshop was organized by the East and Southern African Management Institute (ESAMI) with assistance from the Coordinating Centre for Regional Information Training (CRIT). The specific aims of the workshop were to acquaint…

In the preparation of a thesaurus for the Language Information Network and Clearinghouse System (LINCS), a number of already existing indexing tools was consulted. Many of these provide important secondary sources of terminology and of term relations, in addition to the primary sources available in original texts. Others are models of thesaurus…

The bibliography is a compilation of annotated references on information sciences; conferences, symposia, reviews, supporting research, and STINFO (Scientific and Technical Information Project) activities and is volume IV in a four-volume set on information sciences. It is a revision to the unlimited references in the earlier bibliographies,…
