- Abstract
- Most of the criteria proposed to date for the evaluation of OPACs focus on evaluation of their retrieval function. Argues that the storage function is more important because the quality of information retrieval systems is dependent on the quality of stored information as well as the description and depth of indexing of stored information. States that OPACs should therefore be evaluated from the perspectives of both storage and retrieval functions. Examines 4 studies on criteria for evaluating OPACs and suggests a new evaluation framework based on the work of C.R. Hildreth

- Abstract
- Presents an automatic indexing technique for compound words suitable for an agglutinative language, specifically Korean. Discusses some construction conditions for compound words and the rules for decomposing compound words to enhance the exhaustivity of indexing, demonstrating that this system, mutual information, enhances both the exhaustivity of indexing and the specifity of terms. Suggests that the construction conditions and rules for decomposition presented may be used in multilingual information retrieval systems to translate the indexing terms of the specific language into those of the language required

- Abstract
- 2 concepts of facets have been used in studies of classification systems: one for systems which take hierarchical structure and the other for systems which take multidimensional structure. Both correspond to 'principles of division'. The concepts of facets in multidimensional structure systems is used for addressing a subject from many aspects so should equate to the broadest principle of division in order to grasp a multiplicity of aspects. The concept of facets used in hierarchical systems addresses only the significance of a coherent set of items. This concept is not distinguished from the principle of division and there is no purpose in introducing a concept of facets into hierarchical systems in addition to the principle of division

- Abstract
- Considers classification systems from a structural point of view. Distinguishes between 2 kinds of methods of categorization of classification systems: the first categorized by structure, either hierarchical or multidimensional; and the second by style of expression, either enumerative or sythetic. Identifies 4 leading classification systems according to their structures: DDC, LCC, UDC and Colon Classification. Focuses on DDC referring to 2 interpretatives of its structure, one of which is hierarchical and the other is partially multidimensional. Also relates this to the matter of interpretation of the notation '0', interpreted in one instance as 'generalities', and in another as 'coordination sign'

- Abstract
- Almost all information systems have their own logic. Differentiates between classical and non classical logic, the main example of which is intuitionistic logic which was created to treat partial information. Explains this, discusses the information structure based on intuitionalistic logic, and introduces an intuitionistic information retrieval system. This work represents an introduction to the development of the general theory of partial information and the theory of information retrieval systems which can treat partial information

- Abstract
- Describes a study conducted to compare the use of a new OPAC with that of the card catalogue looking primarily at the area of subject access. Library science students at a private university were asked to respond to questions concerning: the number of subject searches and searches for specific items that they carried out on the OPAC and on the card catalogue; the success rate of the catalogue searches; how the search was carried out (classification number or keywords); librarian assistance required; and knowledge of the Nippon Decimal Classification. Results revealed that while there was an increase in the number of users as a result of the introduction of OPAC facilities, there were certain aspects which required attention such as the area of subject searches

- Abstract
- An information retrieval system for a cataloguing database through the WWW is developed, and experimentally served to Japan MARC and ULIS (Univeristy of Library and Information Science) OPAC data. Since Japanese words are not separated by obvious delimiters, ensuring the same segmentation between the query and the database is a problem. The present system solves the problem by using the multiple hash screening technique for processing both book titles and query strings, based on the same dictionary and using similar algorithms. Database management is handled by ADABAS, reducing management chores and and response time. The effectiveness of the multiple hash screening technique for a Japanese text based information system is examined, and the limitation of the Web's hypertext environment for a bibliographic information retrieval service is discussed
