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

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

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: WWW search engines or surfing tools provide users with catalogues or indexes on the Internet and different ways of searching these catalogues or indexes. There is as yet no standard operation for search tools so that users have to understand the way each one works to use them effectively. Describes, compares and evaluates some of these tools including Infoseek, Lycos, OpenText, WebCrawler, Yahoo!, AltaVista, Inktomi, Excite, Magellan, GAIS, and YAM

Abstract

Discusses the theory and practice of subject headings, the principle and application of subject heading lists in various countries, and the present situation of the Chinese subject heading list in Taiwan. Suggests improvements to the chinese Subject Headings as follows: to increase the number of subject headings; to control the vocabulary to be used; to use fixed fields of Chinese MARC, performing the partial function of subdivision in the chinese Subject Headings; to announce the addition, correction and deletion of subject headings regularly and to compile a users' manual; to establish a national subject heading authority file in the MARC format; and to use the Chinese Subject Headings to organize Internet resources
