Abstract

The automation of Bucharest University Central Library involved the compilation of a dictionary of terms to facilitate postcoordinated searching in accordance with the UDC notation attached to every bibliographic record. Describes the project and demonstrates why a multilingual UDC based thesaurus is considered as ideal indexing and searching tool. The experiment, which applied to Class 8 of UDC (Linguisitcs and Literature), illustrates how all UDC tables can be successfully used to build a thesaurus and the ways in which their limitations can be overcome by a thesaurus

Abstract

Once the library has been through a process of transition from traditional library procedures to automated ones, natural language searching became a necessity for both indexers and searchers. Therefore, aside from the precoordinated classified catalogue we started to build a dictionary of terms in order to make postcoordinate search possible in keeping with the UDC notations assigned to each bibliographic record. After a while we came to the conclusion that the dictionary needed a control of its terms so that synonymous concepts and semantic ambuguities be avoided. The project presented in this paper shows how reality imposed the improvement of the quality of indexing and hence of the searching possibilities. Is also shows the reasons why we consider a multilingual thesaurus based on UDC an ideal indexing and searching device. The experiment applied on class 8 of UDC illustrates the way the UDC tables can be quite successfully used in building a thesaurus due to their qulities and how their limitations can be overcome by a thesaurus. An appendix to the paper contains a sample of the multilingual thesaurus given in both alphabetical and systematic layouts

Abstract

While being theoretically so widely available, information can be restricted from a more general use by linguistic barriers. The linguistic aspects of the information languages and particularly the chances of an enhanced access to information by means of multilingual access facilities will make the substance of this thesis. The main problem of this research is thus to demonstrate that information retrieval can be improved by using multilingual thesaurus terms based on an intermediate or switching language to search with. Universal classification systems in general can play the role of switching languages for reasons dealt with in the forthcoming pages. The Universal Decimal Classification (UDC) in particular is the classification system used as example of a switching language for our objectives. The question may arise: why a universal classification system and not another thesaurus? Because the UDC like most of the classification systems uses symbols. Therefore, it is language independent and the problems of compatibility between such a thesaurus and different other thesauri in different languages are avoided. Another question may still arise? Why not then, assign running numbers to the descriptors in a thesaurus and make a switching language out of the resulting enumerative system? Because of some other characteristics of the UDC: hierarchical structure and terminological richness, consistency and control. One big problem to find an answer to is: can a thesaurus be made having as a basis a classification system in any and all its parts? To what extent this question can be given an affirmative answer? This depends much on the attributes of the universal classification system which can be favourably used to this purpose. Examples of different situations will be given and discussed upon beginning with those classes of UDC which are best fitted for building a thesaurus structure out of them (classes which are both hierarchical and faceted)...

Abstract

The paper introduces TinREAD (The Information Navigator for Readers), an integrated library system produced by IME Romania. The main feature of interest is the way TinREAD can handle a classification-based thesaurus in which verbal index terms are mapped to classification notations. It supports subject authority control interlinking the authority files (subject headings and UDC system). Authority files are used for indexing consistency. Although it is said that intellectual indexing is, unlike automated indexing, both subjective and inconsistent, TinREAD is using intellectual indexing as input (the UDC notations assigned to documents) for the automated indexing resulting from the implementation of a thesaurus structure based on UDC. Each UDC notation is represented by a UNIMARC subject heading record as authority data. One classification notation can be used to search simultaneously into more than one corresponding thesaurus. This way natural language terms are used in indexing and, at the same time, the link with the corresponding classification notation is kept. Additionally, the system can also manage multilingual data for the authority files. This, together with other characteristics of TinREAD are largely discussed and illustrated in the paper. Problems encountered and possible solutions to tackle them are shown.

Abstract

The article describes the research done over a bibliographic database in order to show the impact the specificity of the knowledge organising tools may have on information retrieval (IR). For this purpose two multilingual Universal Decimal Classification (UDC) based thesauri having different degrees of specificity are considered. Issues of harmonising a classificatory structure with a thesaurus structure are introduced, and significant aspects of information retrieval in a multilingual environment are examined in an extensive manner. Aspects of complementarity are discussed with particular emphasis on the real impact produced on IR by alternative search facilities. Finally, a number of conclusions are formulated as they arise from the study.

Abstract

The existence of huge amounts of information available in information systems and networks worldwide imposes the creation of adequate tools able to efficiently organize it and allow its retrieval across geographical, linguistic and cultural boundaries. An indexing language covering all areas of knowledge and converting the language-independent structure of a classification system like the Universal Decimal Classification into a thesaurus structure in more than one language seems to be a solution. Among the key attributes of the indexing language thus obtained we can mention: consistency in indexing, control an terms, user-friendliness. The paper presents the great potential in information retrieval of the combined retrieval method by means of a case study. 1. Introduction Among the consequences of the rapid development of the global information society a major one is the existence of huge amounts of information stored in information systems and networks across geographical, linguistic and cultural boundaries. The need was imposed to create tools and technologies able to efficiently organize and allow retrieval of information in this universal context. Information professionals had to cope not only with the multitude of knowledge organisation and representation systems but also with the multitude of languages the available information is stored in order to provide the users with effective information retrieval tools. For this purpose a real language industry has been developed, theoreticians and researchers making considerable efforts to find feasible solutions to problems of multilingual access by way of natural language processing and machine translation methodologies. Such corporate efforts belong to the CoBRA+ working group for multilingual access to subjects (MACS) or to the cross-language information retrieval (CLIR) tracks of the Text Retrieval Conferences that annually report the progress made in multilingual information access and retrieval. The encouraging results they have obtained so far are still confined to discipline/domain restrictions and most of their achievements are based an language pairs rather than multiple language combinations.
