    Abstract
    Metadata is a resource which can assist the information retrieval of digital documents on the Internet. In designing a metadata system, it is necessary to consider the characteristics of digital documents, such as the variety of file formats, frequent format transformation and the difficulty of distinguishing between the different versions. Provides a brief analysis of some existing metadata formats, and introduces several pronciples for the future development of cataloguing on the Internet. Briefly describes the Metadata Experimental System (MES) currently under development, and located at the author's homepage

    Abstract
    In a prototype model of a computer aided Chinese classification system, 4 different modules were included: the keyword searching type, user's predomination type, expert wizard type and versatile type. These 4 modules work in different ways whilst sharing the same concept. The keyword searching type finds the most suitable category by scanning the keywords of all categories in a database; it is useful for entrance level staff. The user's predomination type allows the user to key in the proper category to size down the number of returning data; the user then picks the best category by browsing the built in keywords. This module is suitable for professional librarians. The expert wizard type actively leads the user to choose the best category one by one. The versatile type is a mixture of the other 3 types

    Abstract
    Reports results of a questionnaire survey, the main purpose of which was to study and understand library users' perceptions of reference librarians' body language and its influence on the users' satisfaction of the reference interviews. The aim was to improve the overall quality of reference services. The study was undertaken in the National Yang-Ming University Library and involved 162 data samples. Describes the statistical methods used and the content analysis applied to the analysis of the data. Findings indicate that users prefer librarians' to adopt an approachable mode: arms relaxed; frequent eye contact; greeting users with a smile; hands unoccupied, and with appropriate hand gestures. Contrarily, preoccupation mode: with arms crossed; frowning; and hands busy with work; conveys an unfriendly message to library users. Concludes that the findings could be a valuable tool for reference librarians to develop their interviewing techniques in terms of body language and so improve the quality of referecne services

    Abstract
    Investigates the characteristics of Journal Citation Reports (JCR) through the study of the Science Citation Index (SCI). Other criteria for evaluating a journal are also discussed. The compilation process of SCI data, and the characteristics, applications and limitations of SCI are studied. A detailed description of JCR is provided including: journal ranking listing, citing journal listing, cited journal listing, subject category listing, source data, impact factor, immediacy index, cited half-life and citing half-life. The applications and limitations of JCR are also explored. In addition to the criteria listed in JCR, the size, circulation and influence of journals are also considered significant criteria fir evaluation purposes

    Abstract
    With the rapid rise in numbers of electronic documents on the Internet, how to effectively assign topics to documents become an important issue. Current research in this area focuses on the behaviour of nouns in documents. Proposes, however, that nouns and verbs together contribute to the process of topic identification. Constructs a mathematical model taking into account the following factors: word importance, word frequency, word co-occurence, and word distance. Preliminary experiments ahow that the performance of the proposed model is equivalent to that of a human being

    Abstract
    Automatic keyword extraction is an important and fundamental technology in an advanced information retrieval systems. Briefly compares several major keyword extraction methods, lists their advantages and disadvantages, and reports recent research progress in Taiwan. Also describes the application of a keyword extraction algorithm in an information retrieval system for relevance feedback. Preliminary analysis shows that the error rate of extracting relevant keywords is 18%, and that the precision rate is over 50%. The main disadvantage of this approach is that the extraction results depend on the retrieval results, which in turn depend on the data held by the database. Apart from collecting more data, this problem can be alleviated by the application of a thesaurus constructed by the same keyword extraction algorithm

    Abstract
    Identifies 6 types of searches on the basis of paudsing behaviour by using cluster analysis. The 6 types of search were highly associated with search fleuncy and the construction of a mental model. Examines learning during multiple searches on the basis of the 6 types. Finds that searchers gain more experience, increase their searching proficiency and become more fluent at searching while online. The changes of search level in multiple searches showed that most searchers moved towards greater fleuncy

    Abstract
    Discusses access to the Internet. Although the number of Internet users has increased since 1993, the technology is still unavailable to many. High income, highly educated people are more easily able to access new media than those who are less well off. Such a knowledge gap may contribute more to social disparity in future. To ensure that most people have access to computer networks, future national policy should move from universal service to universal access. Network policy should offer not only to make networks available to all but also to ansure people's ability to access the content

    Abstract
    The Chinese Science Citation Database (CSCD) is a significant document database on mainland China, which has been built up by the Documentation and Information Centre of the Chinese Academy of Sciences. Briefly introduces the background to CSCD, and discusses in detail its development and application, source journals and citation data, data processing methods, subject scope, compilation regulations, stylistic rules and layout, and usage directions for both the printed and CD-ROM editions of CSCD which have been published from the data

    Abstract
    Notes that in automatic indexing of Chinese words using dictionary matching methods, there is some difficulty in the indexing of proper nouns. Presents a solution called dynamic morphological indexing, based on work using automatic indexing of archive documents. Presents the algorithm for this solution

    Abstract
    One of the major causes of search failures in information retrieval systems is vocabulary mismatch. Presents a solution to the vocabulary problem through 2 strategies known as term suggestion (TS) and term relevance feedback (TRF). In TS, collection specific terms are extracted from the text collection. These terms and their frequencies constitute the keyword database for suggesting terms in response to users' queries. One effect of this term suggestion is that it functions as a dynamic directory if the query is a general term that contains broad meaning. In term relevance feedback, terms extracted from the top ranked documents retrieved from the previous query are shown to users for relevance feedback. In the experiment, interactive TS provides very high precision rates while achieving similar recall rates as n-gram matching. Local TRF achieves improvement in both precision and recall rate in a full text news database and degrades slightly in recall rate in bibliographic databases due to the very limited source of information for feedback. In terms of Rijsbergen's combined measure of recall and precision, both TS and TRF achieve better performance than n-gram matching, which implies that the greater improvement in precision rate compensates the slight degradation in recall rate for TS and TRF
