Abstract: Evaluates the potential of the electronic library (virtual library) to provide information for the public in light of Ranganathan's five laws of library science. Rephrases certain laws in the context of electronic information resources and points to opportunities to make additions to the laws in light of news services and the Internet

Abstract: The concept of equivalence is considered in the context of compatibility of thesauri. Intra and interlanguage equivalence in natural languages as well as linguistic equivalence versus descriptor equivalence are specified. The consideration leads to the definition of 2 new concepts: dictionary equivalence and indexing equivalence, which are both instances of descriptor equivalence. Indexing equivalence is further divided into potential and concrete indexing equivalence. The potential indexing equivalence between the descriptors of Liikunnan ja urheilung asiasanasto (Subject headings forphysical education and sport) and the Canadian Sport Thesaurus is then described in the light of 2 different descriptor collections

Abstract: Presents a critical review of the sense making theory of Brenda Dervin, an important contribution to the theory building in information studies. Special attention is given to the use of the sense making theory in empirical research. Claims that the difficulties faced in data collection and analysis when applying sense making as a methodology are dur to the fact that the conceptual apparatus developed by Dervin has not yet been sufficiently elaborated. Dervin, along with many other theorizers of information seeking and use, is also criticized for ignoring the social nature and context of knowledge and thought. The construction of meaning, and thinking in general, it not only a subjective process but it also involves socially shared representations and ideas

Abstract

Homonymy is known to often cause false drops in free text searching in a full text database. The problem is quite common and difficult to avoid in Finnish, but nobody has examined it before. Reports on a study that examined the frequency of, and solutions to, the homonymy problem, based on searches made in a Finnish full text database containing about 55.000 newspaper articles. The results indicate that homonymy is not a very serious problem in full text searching, with only about 1 search result set out of 4 containing false drops caused by homonymy. Several other reasons for nonrelevance were much more common. However, in some set results there were a considerable number of homonymy errors, so the number seems to be very random. A study was also made into whether homonyms can be disambiguated by syntactic analysis. The result was that 75,2% of homonyms were disambiguated by this method. Verb homonyms were considerably easier to disambiguate than substantives. Although homonymy is not a very big problem it could perhaps easily be eliminated if there was a suitable syntactic analyzer in the IR system

Abstract

The survey took place in the year of 1990. 16 librarians and information scientists took part from 10 different departments of Oulu University Library. 581 titles were tested, 70% in English and the rest in Swedish, German and Finnish. The reason for the survey was to find out whether it would be worth using a Finnish indexing system alongside UDC. As an average it takes 6 minutes to familiarize with an item and another 6 minutes to classify and catalogue it. The results are compared with other similar projects in Finland and abroad
