- 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
- Provides an explpanation of the German cataloguing rules (RAK) focusing on conceptual rules and describes their current situation and the likely nature of future revisions. The special characteristics of RAK are the clearly defined 'basic bibliographic concepts (Grundbegriffe)' as literary units and the related concepts of item (Vorlage), edition (Ausgabe) and work (Werk). RAK will be revised in the near future as RAK2 with a conceptual framework based on AACR2, clearly defined bibliographical concepts on literary units and compatibility with RAK-WB

- 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
- Information retrieval functions in digital libraries have a different context from those which apply to searching commercial databases or OPACs. Different methods of browsing in this context are described, but the retrieval function should also include ordinary Boolean searching. Conversion of printed materials to electronic format using OCR can result in errors, which may cause problems for keyword searching. The n-gram method of approximate or fuzzy matching to reduce this problem is described

- Abstract
- Discusses indexing methods for moving graphical images and suggests the use of the new indexing language, the Moving Picture Description Language (MPDL) which has the following 7 frames: subject, time, location, object, characteristics, actions, and sensibility. MPDL allows indexers to assign one or more indexing terms to each frame. The retrieval experiment used 110 video images obtained from television news indexed by MPDL and other indexing methods and revealed that MPDL was the superior method. Suggests that MPDL presents many opportunities for improving the indexing and retrieval of the moving graphical image

- 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
