- Abstract
- Describes a design for ideal online subject and author thesauri. The subject thesaurus is a graphic thesaurus with a semantic network, so the spread activation assumption can be applied. The hierarchical relationship is broken into 3 specific relations, so automated inheritance can be performed. The associated relationship is separated with several specific relationships, so spatial recognition can function well. This thesaurus will provide variety and complexity to deal with uncertainty and will be a user constructed, user enhanced hyperthesaurus that serves as an analogue of the human mind. The author thesaurus is designed to show all authors which are alphabetically adjacent to a given author as well as other authors whose subject area is close to that of the given author

- Abstract
- Automatic thesaurus construction is accomplished by extracting term relations mechanically. A popular method uses statistical analysis to discover the term relations. For low frequency terms the statistical information of the terms cannot be reliably used for deciding the relationship of terms. This problem is referred to as the data sparseness problem. Many studies have shown that low frequency terms are of most use in thesaurus construction. Characterizes the statistical behaviour of terms by using an inference network. Develops a formal approach using a Baysian network for the data sparseness problem

- 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
- 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
- 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
- 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 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
- 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
- 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
- We discuss whether it is feasible to build intelligent rule- or weight-based algorithms into general-purpose software for interactive thesaurus navigation. We survey some approaches to the problem reported in the literature, particularly those involving the assignement of 'link weights' in a thesaurus network, and point out some problems of both principle and practice. We then describe investigations which entailed logging the behavior of thesaurus users and testing the effect of thesaurus-based query enhancement in an IR system using term weighting, in an attempt to identify successful strategies to incorporate into automatic procedures. The results cause us to question many of the assumptions made by previous researchers in this area

- Abstract
- The need for thesauri to help users in their search for information in online information systems has been discussed for several decades. Many wide-ranging contributions have been made to solve this problem. Nevertheless, investigation is needed to design a thesaurus structure based on what is relevant for users and generators of information within a specific subject domain. Explores the possibility of creating a thesaurus from the cognitive viewpoint. This approach is based on a system that organizes its representation of knowledge or its classification as closely as possible to the authors' and users' images of the subject domain with the objective of increasing the interaction between users and texts, and thus the communication in a given information retrieval system. Discourse analysis is used as a main method to identify the categories and its relevance for building such a structure is discussed
