- Abstract
- A central consideration in the study of whole language semantic space as encoded in thesauri is word sense comparability. Shows how word sense comparability can be adequately expressed by the logical implications and rules from Formal Concept Analysis. Formal concept analysis, a new approach to formal logic initiated by Rudolf Wille, has been used for data modelling, analysis and interpretation, and also for knowledge representation and knowledge discovery

- Abstract
- A metathesaurus is a set made of a reference thesaurus and various forms of indexing languages attached to it. Among these, the sub-thesauri cover restricted fields in more detail. A functional definition of the sub-thesaurus is proposed: elements, relationships, sub-systems and rules to be respected to preserve the possibilities for communication via the reference thesaurus. Considerations on the methods of presentation, the use and the compilation are also given

- Abstract
- A thesaurus contains a set of terms or features that may be used to represent recorded information, including prose documents or scientific data sets. The focus of this work is on the basic structural nature of a thesaurus itself, not on how people develop a thesaurus or how a thesaurus effects retrieval performance. Thesauri in this research are automatically developed in a simulation from sets of randomly or exhaustively generated documents. Each thesaurus is generated by the Thesaurus Generator software from a set of several hundred documents, and thousands of different document sets are used as input to the Thesaurus Generator, producing thousands of thesauri. Thus, thousands of thesauri are generated for each data point in accompanying graphs. The characteristics of this large number of thesauri are studied so that the relationships between thesaurus parameters can be determined. Some rules governing these relationships are suggested, addressing factors such as tree height and width, number of tree roots in thesauri, and number of terms available for the vocabulary. How these parameters scale as vocabularies grow is addressed. These results apply to various information systems that contain features with hierarchical relationships, including many thesauri and ontologies.

- Abstract
- Presents a state of the art review of the literature of expert systems in library and information science, involving exhaustive searches of all major LIS CD-ROM databases (LISA, ERIC, LiLi, INSPEC etc.) and bibliographies appended in review articles. The search retrieved 679 references, comprising 362 periodical articles, 180 conference proceedings, 63 books articles, 28 theses and 46 monographs. The growth of the literature peaked between 1989 and 1990 and subsequently declined after 1992. Over 1/3 (287) covered intelligent front ends and interfaces for online searching and retrieval, followed by applications in reference service (113), classification, indexing and abstracting (86) and cataloguing (7). The most productive periodicals comprised 6 titles, of which 'Information processing and management' topped the lsit: 43 authors were found to contribute between 5 and 35 articles each, hence contributing 32,19% of the total contributors. 382 of the publications were single author works, 172 were by 2 authors, 72 were by 3 authors and 49 were by 4 or more authors. Only 161 titles were expressive enough to reveal both the name and function of systems being developed

- Abstract
- In this paper, after an introduction about problems of multilingual information languages, the rules and recommendations of the Guidelines for the establishment and development of multilingual thesauri for non-equivalence and partial equivalence of terms in different languages are discussed. Artificial terms are not very useful in searching, because most users are not willing to use a thesaurus to find the right descriptor. On the other hand indexers need guidance on how to index and therefore need a thesaurus with all desirable and necessary relations. It is suggested that bibliographic online systems can take over some of the functions for the searcher from the thesaurus and that a few new relations could be helpful to an indexer

- 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
- Describes the thesaurus that has been created at the Library of the Polish Parliament and is one element of the STEBIS system (System Tezaurusow Biblioteki Sejmowej). Discusses and illustrates with examples the rules of selecting vocabulary terms. The main aim is to map the contents of Polish and foreign documents and to preserve compatibility with the EUROVOC Thesaurus of the European Parliament. Emphasizes the need for the systematization of terms within one logical setup, with regard to the alphabetical and systematic part of the thesaurus and the multilingual character of the EUROVOC Thesaurus

- Abstract
- Presents a framework for knowledge discovery and concept exploration. In order to enhance the concept exploration capability of knowledge based systems and to alleviate the limitation of the manual browsing approach, develops 2 spreading activation based algorithms for concept exploration in large, heterogeneous networks of concepts (eg multiple thesauri). One algorithm, which is based on the symbolic AI paradigma, performs a conventional branch-and-bound search on a semantic net representation to identify other highly relevant concepts (a serial, optimal search process). The 2nd algorithm, which is absed on the neural network approach, executes the Hopfield net parallel relaxation and convergence process to identify 'convergent' concepts for some initial queries (a parallel, heuristic search process). Tests these 2 algorithms on a large text-based knowledge network of about 13.000 nodes (terms) and 80.000 directed links in the area of computing technologies

- Abstract
- Thesauri are valuable structures for Information Retrieval systems. A thesaurus provides a precise and controlled vocabulary which serves to coordinate dacument indexing and document retrieval. In both indexing and retrieval, a thesaurus may be used to select the most appropriate terms. Additionally, the thesaurus can assist the searcher in reformulating search strategies if required. Examines the important features of thesauri. This should allow the reader to differentiate between thesauri. Next, a brief overview of the manual thesaurus construction process is given. 2 major approaches for automatic thesaurus construction have been selected for detailed examination. The first is on thesaurus construction from collections of documents,a nd the 2nd, on thesaurus construction by merging existing thesauri. These 2 methods were selected since they rely on statistical techniques alone and are also significantly different from each other. Programs written in C language accompany the discussion of these approaches
