- Abstract
- This 1993 edition is the authoritative guide constructing single-language thesauri, one of the most powerful tools for information retrieval. Written by experts, Z39.19 shows how to formulate descriptors, establish relationships among terms, and present the information in print and on a screen. Also included are thesaurus maintenance procedures and recommended features for thesaurus management systems

- Abstract
- Despite early claims to the contemporary, thesauri continue to find use as access tools for information in the full-text environment. Their mode of use is changing, but this change actually represents an expansion rather than a contrdiction of their utility. Thesauri and similar vocabulary tools can complement full-text access by aiding users in focusing their searches, by supplementing the linguistic analysis of the text search engine, and even by serving as one of the tools used by the linguistic engine for its analysis. While human indexing contunues to be used for many databases, the trend is to increase the use of machine aids for this purpose. All machine-aided indexing (MAI) systems rely on thesauri as the basis for term selection. In the 21st century, the balance of effort between human and machine will change at both input and output, but thesauri will continue to play an important role for the foreseeable future

- Abstract
- The originality of this book, which deals with such a new subject matter, lies in the application of methods and concepts never used before - such as Ontologies and Taxonomies, as well as Thesauri - to the ordering of knowledge based on primary information. Chapters in the book also examine the study of Ontologies, Taxonomies and Thesauri from the perspective of Systematics and General Systems Theory. "Ontologies, Taxonomy and Thesauri in Information Organisation and Retrieval" will be extremely useful to those operating within the network of related fields, which includes Documentation and Information Science.

- Abstract
- Describes the backgroud to the construction of a thesaurus at Hydro-Quebec, Quebec, Canada. Several information units, linked to form a network, share the same bibliographic database. The need for coherence and efficiency was the principle motive for the construction of the multidisciplinary thesaurus. Describes the construction process, discusses the specifity of the tool, its circulation, and considers its use on a partnership basis with other information services

- Abstract
- This article provides an overview of recent developments relating to the application of thesauri in information organisation and retrieval on the World Wide Web. It describes some recent thesaurus projects undertaken to facilitate resource description and discovery and access to wide-ranging information resources on the Internet. Types of thesauri available on the Web, thesauri integrated in databases and information retrieval systems, and multiple-thesaurus systems for cross-database searching are also discussed. Collective efforts and events in addressing the standardisation and novel applications of thesauri are briefly reviewed.

- Abstract
- Discusses the various functions which a thesaurus can have. Highlights the main function of a thesaurus in vocabulary control, eliminating natural language ambiguity and providing consistency of indexing, and serving as an aid in the searching process. Further discusses the function of a search thesaurus in serving as a user's aid in full text systems and in free indexing systems, and the additional function of an online thesaurus integrated with an online database, that of a vocabulary master file. Notes also how a thesaurus can function as a switching language or intermediary lexicon in multidatabase systems

- Abstract
- To show the difference and explain the move to a new kind of thesauri in the information science area, some of the main characteristics of conventional thesauri are pointed out as well as their side-effects. The new approaches for thesauri apllication are seen to exist in (1) expert systems, (2) interface systems, (3) object oriented design and programming, (4) hypertext systems, (5) machine translation, and (6) machine abstracting. These areas are shortly described including also the new problem which they might create. A discussion of the limitations of the new thesaurus application areas finishes the article which challenges, finally, an awareness to meet the new possibilities of a thesaural retrieval

- Abstract
- The information retrieval problem is described starting from an analysis of the concepts 'user's information request' and 'information offerings of texts'. It is shown that natural language phrases are a more adequate medium for expressing information requests and information offerings than character string based query and indexing languages complemented by Boolean oprators. The phrases must be represented as concepts to reach a language invariant level for rule based relevance analysis. The special type of representation called advanced thesaurus is used for the semantic representation of natural language phrases and for relevance processing. The analysis of the retrieval problem leads to a symmetric system structure

- Abstract
- Shows that it is possible to construct a lexical database by combining material from a number of machine-readable sources. Discusses the kind of lexical information required for applications in information retrieval and in other natural language processing areas, such as database interfaces and automatic filing systems. Describes the organization of the lexical database which is stored in an Oracle relational database management system and the design of the tables that comprise the database. In addition to the traditional alphabetic listing, access is privided from roots to derived forms and from derived forms to roots, and also through lexical and semantic relations between words, so that the database functions as a thesaurus as well as a dictionary. The database is designed to be open-ended and self-defined. Every attribute of every table is defined in the database itself. The lexical database can easily be extended through an SQL forms interface that facilitates additions to the tables
