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: Describes the ongoing project for the creation of a Japanese version of the BSO. Translation of the original English BSO into Japanese was completed in April 1995. BSO-mrJ has 3 components: a standardized MARC format for data exchange; an object-oriented database; and a device for human-recognizable classification output

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

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

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

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

Attempts to provide a theoretical rationale for the taxonomy of bibliographic relationships between a given work and its related bibliographic entities. Examines the bibliographic structure of the document carrying the messages in terms of their bibliographic functions of use and preservation, since the most common bibliographic relationships are normally revealed within the document itself. Defines the bibliographic characteristics of the document from the perspective of an analysis of the pattern of their structural elements. Presents 4 dimensions of the bibliographic structure as a frame of reference for the categorisation of bibliographic relationships, together with their subordinate types of equivalent relationships, focusing on common structural patterns revealed with in each entity itself

Abstract

Several years ago a conceptual framework was proposed that was designed to capture a bibliographic item by means of a structured approach and to present it in a structured manner in a bibliographic record: the 3-layered approach. Recently IFLA published the report of a study entitled 'Functional requirements for bibliographic records: draft report for worldwide review' for the purpose of a thorough reexamination of the question based on an analysis of user needs. The IFLA report attempted to capture the bibliographic universe through E-R analysis and to define entities, attributes of entities and relationships between them, all of which constitute the bibliographic universe. Compares the 3-layered model and the IFLA model culminating in a reevaluation of the 3-layered model

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

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

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

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
