- Abstract
- The development of the revised 9th ed. is described, giving examples of problem areas in the 8th ed. Individual sections are discussed. Although improvements have been made in notation, 'see references', clarification of relations between classes, supplementary tables etc., the are still areas requiring further work

- Abstract
- Reports a survey conducted in April 1997 of 136 Japanese WWW and Telnet OPACs from the persepctive of their functions and user interfaces. These included: types of searchable files; access points; kinds of displays; login commands; search methods; Boolean operation; help functions; search history; and browsing of indexed terms. Results indicate a sharp rise in the number of WWW OPACs and problems with the provision of functions and user interfaces by Japanese WWW OPACs

- 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
- 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
- Reviews a series of studies conducted by C.C, Kuhlthau who investigated users' information seeking behaviour in libraries over a 10 year period. In her study she constructed and Information Search Process (ISP) Model which represents aspects of user activities as a whole including feelings, thoughts and actions or behaviour. Argues that, while the ISP model sheds new light on user studies, it has problems in the following areas: problem solving processes; the understanding of 'feelings'; and the method of investigating users' information seeking behaviour. Recommends that the ISP model be reconstructed from different perspectives and verified in areas other than libraries. This may lead to the development of a new model of information seeking

- 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
- 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
- In online retrieval search results do not always match the intent in spite of using correct keywords (descriptors). One of the causes of this problem is found in the hierarchical structures of the thesaurus, which often contains relations between broader and narrower concepts, the opposite of which is not necessarily true. Some examples are described from 2 thesauri, MeSH and JICST. In these cases searchers need to make an effort to increase precision

- 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

- Reports a study to clarify the nature and functions of 'see also' references in the dictionaly of terminology by surveying 3 such dictionaries, using semantic relations between referring entries and referred entries as a key. The following points were clarified: major types of semantic relations between referring and referred entries and their quantitative tendencies; correlations between the general nature of dictionaries and overall tendencies of 'see also' references; some tendencies concerning the directions of references under some semantic relations; and correlations between the nature of dictionaries and the directions of 'see also' references

- 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
- 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
- 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
- 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
