- 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

- Abstract
- The Nippon Decimal Classification (NDC) system, extensively used in Japanese libraries, was devised in 1929. It is difficult to use NDC to classify world literature, such as fiction in English by non American, non British writers. This is not necessarily straightforward in other classification schemes but a survey of 40 Japanese university libraries, of which 24 responded, showed remarkable inconsistencies in the treatment of 22 world literature authors. NDC clearly needs updating to deal with this problem

- Abstract
- Description of an attempt to improve OPAC subject access at Kobe University Library using Nippon Decimal Classification, 8th ed. (NDC8). Examines the theoretical aspects of using a classification for subject searching, then explains the Kobe system. Using the NDC8 machine-readable data file, a database was created for the OPAC, incorporating class numbers and subject headings. Difficulties arise from subdivisions and the structure of NDC8 itself, but it is an important area for development

- 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

- 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
- A survey of Japanese OPACs available on the Internet was conducted relating to use of keywords for subject access. The findings suggest that present OPACs are not capable of storing subject-oriented information. Currently available keyword access derives from a merely title-based retrieval system. Contents data should be added to bibliographic records as an efficient way of providing subject access, and costings for this process should be estimated. Word standardisation issues must also be addressed
