- Abstract
- Most indexed databases now include their thesauri and/or coding in their bibliographic files, searchable at the databases' online connect rates. Assesses the searchability of these on the different hosts. Thesauri and classifications are also available as diskette or CD-ROM products. Describes a number of these, highlighting the diskette thesaurus from IFI/Plenum Data for its flexible databases, the CLAIMS Uniterm and Comprehensive indexes to US chemical patents

- Abstract
- The patterns of overlap between terms which are closely related in a thesaurus are considered. The relationships considered are parent/child, in which one term is a broader term of the other, and sibling in which to 2 terms share the same broader term. The patterns of overlap observed in the MeSH thesaurus with respect to selected MEDLINE postings are examined. The implications of the overlap patterns are discussed, in particular, the impact of the overlap patterns on the potential effectiveness of a proposed algorithm for handling negation is considered.

- Abstract
- A thesaurus in the controlled vocabulary environment is a tool designed to support effective infonnation retrieval (IR) by guiding indexers and searchers consistently to choose the same terms for expressing a given concept or combination of concepts. Terms in the thesaurus are linked by relationships of three well-known types: equivalence, hierarchical, and associative. The functions and properties of these three basic types and some subcategories are described, as well as some additional relationship types conunonly found in thesauri. Progressive automation of IR processes and the capability for simultaneous searching of vast networked resources are creating some pressures for change in the categorization and consistency of relationships.

- Abstract
- The present study investigates the ability of a bibliometric based semi-automatic method to select candidate thesaurus terms from citation contexts. The method consists of document co-citation analysis, citation context analysis, and noun phrase parsing. The investigation is carried out within the specialty area of periodontology. The results clearly demonstrate that the method is able to select important candidate thesaurus terms within the chosen specialty area.

- Abstract
- The benefits of a well constructed thesaurus to an information retrieval system have long been recognised by both researchers and practitioners in the field. Examines both early and current approaches to automatic thesaurus construction and describes an approach to the automatic generation of global thesauri based on the term discrimination value model of Salton Yang, and Yu and on an appropriate clustering algorithm. This method has been implemented and applied to 2 document collections. Preliminary results indicate that this method, which produces improvements in retrieval performance in excess of 10 and 15% in the test collections, is viable and worthy of continued investigation.

- Abstract
- The purpose of this selected bibliography is to introduce issues and problems in relation to thesaurus construction and to present a set of readings that may be used in practical thesaurus design. The concept of thesaurus is discussed, the purpose of the thesaurus and how the concept has evolved over the years according to new IR technologies. Different approaches to thesaurus construction are introduced, and readings dealing with specific problems and developments in the collection, formation and organisation of thesaurus concepts and terms are presented. Primarily manual construction methods are discussed, but the bibliography also refers to research about techniques for automatic thesaurus construction.

- Abstract
- After a period of experiment and evolution in the 1950s and 1960s, a fairly standard format for thesauri was established with the publication of the influential Thesaurus of Engineering and Scientific Terms (TEST) in 1967. This and other early thesauri relied primarily an the presentation of terms in alphabetical order. The value of a classified presentation was subsequently realised, and in particular the technique of facet analysis has profoundly influenced thesaurus evolution. Thesaurofacet and the Art & Architecture Thesaurus have acted as models for two distinct breeds of thesaurus using faceted displays of terms. As of the 1990s, the expansion of end-user access to vast networked resources is imposing further requirements an the style and structure of controlled vocabularies. The international standards for thesauri, first conceived in a print-based era, are badly in need of updating. Work is in hand in the UK and the USA to revise and develop standards in support of electronic thesauri.

- Abstract
- The Nuovo soggettario, the official Italian subject indexing system edited by the National Central Library of Florence, is made up of interactive components, the core of which is a general thesaurus and some rules of a conventional syntax for subject string construction. The Nuovo soggettario Thesaurus is in compliance with ISO 25964: 2011-2013, IFLA LRM, and FAIR principle (findability, accessibility, interoperability, and reusability). Its open data are available in the Zthes, MARC21, and in SKOS formats and allow for interoperability with l library, archive, and museum databases. The Thesaurus's macrostructure is organized into four fundamental macro-categories, thirteen categories, and facets. The facets allow for the orderly development of hierarchies, thereby limiting polyhierarchies and promoting the grouping of homogenous concepts. This paper addresses the main features and peculiarities which have characterized the consistent development of this categorical structure and its effects on the syntactic sphere in a predominantly pre-coordinated usage context.

- Abstract
- This paper describes a proposal for a new approach to thesaurus design and construction that could have significant implicantions for change in the way multilingual thesauri are handled and integrated with each other. The formula presented here has its origin in the work of the German Thesaurus Committee and has had input from a number of scientists and practitioners int he field. The emphasis is on the various types of relationships found among concepts, notiions and universals in languages. These relationships are analysed and refined beyond the approach taken in existing thesauri. This proposal is very much at the discussion stage and the author invites the assistance of interested readers through criticisms, discussion and dialogue. Applications of the proposed thesaurus are included and the major goal of this proposal is to provide the basis for improved desing and integration of multilingual thesauri

- Abstract
- The need for Persian thesauri became apparent during the late 1960s with the advent of documentation centres in Iran. The first Persian controlled vocabulary was published by IRANDOC in 1977. Other centres worked on translations of existing thesauri, but it was soon realised that these efforts did not meet the needs of the centres. After the Islamic revolution in 1979, the foundation of new centres intensified the need for Persian thesauri, especially in the fields of history and government documents. Also, during the Iran-Iraq war, Iranian research centres produced reports in scientific and technical fields, both to support military requirements and to meet society's needs. In order to provide a comprehensive thesaurus, the Council of Scientific Research of Iran approved a project for the compilation of such a work. Nowadays, 12 Persian thesauri are available and others are being prepared, based on the literary corpus and conformity with characteristics of Iranian culture.
