- Abstract
- Classification plays a very important role in the traditional organization and manual retrieval of documents. The advantages of classification are becoming evident again in the networked environment, in the areas of online browsing, organization of non text information, management of hypertext, and as a common language for the organization of information, which will promote the integration of classification schemes and thesauri

- Abstract
- The concept of faceted classification has its long history and importance in the human civilization. Recently, more and more consumer Web sites adopt the idea of facet analysis to organize and display their products or services. The aim of this article is to review the origin and develpment of faceted classification, as well as its concepts, essence, advantage and limitation. Further, the applications of faceted classification in various domians have been explored.

- 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
- In remembrance of Magda Heiner-Freiling who dedicated her professional efforts in promoting the sharing of subject access among world libraries, we sincerely wish to add our contribution to the endeavor she started and dreamed of finishing by writing this paper in Chinese, introducing SKOS and discussing its applications in transferring the largest controlled vocabulary in China, the Chinese Classified Thesaurus (CCT), into a SKOS-based knowledge organization system (KOS). The paper discusses the conceptual models of concept-based and term-based systems, the converting solutions of CCT, and the potential usage of a KOS registry built on SKOS and other Web-based protocols and technologies.

- Abstract
- Uses an information processing approach to analyse the behaviour of end users in searching online bibliographic databases, with particular emphasis on errors made. Following instruction in online searching, 41 students and 3 faculty end users conducted 79 subject searches. Analysis of search transcripts identified 119 reasons for errors. Errors occured most frequently in connection with functions, moves, and elements of 'create and develop sets' and 'display and print records'. Surprisingly, the results do not indicate that end users make errors less frequently as they gain more experience and practice, although syntax-related errors do decrease with time

- Abstract
- The incresing ned to make library materials more speedily available to impatient readers is causing libraries in Taiwan to become interested in copy cataloguing and outsourcing (contracting out). Reviews the concept of the Core Bibliographic Record in the USA as an important part of cooperative cataloguing systems and studies the Program for Cooperative Cataloguing (PCC) Core

- Abstract
- Describes a design for ideal online subject and author thesauri. The subject thesaurus is a graphic thesaurus with a semantic network, so the spread activation assumption can be applied. The hierarchical relationship is broken into 3 specific relations, so automated inheritance can be performed. The associated relationship is separated with several specific relationships, so spatial recognition can function well. This thesaurus will provide variety and complexity to deal with uncertainty and will be a user constructed, user enhanced hyperthesaurus that serves as an analogue of the human mind. The author thesaurus is designed to show all authors which are alphabetically adjacent to a given author as well as other authors whose subject area is close to that of the given author

- Abstract
- Describes a study aimed at exploring possible applications for PRECIS for indexing Chinese documents, generating Chinses subject indexes, and for facilitating online information retrieval. A random sample of 498 Chinese subject indexing strings was taken from the Index to Chinese Periodical Literature and a comprehensive test of the PRECIS role operators was carried out. 18 problem areas were isolated and grouped into 8 categories. These problems stemmed mainly from syntactic differences between English and Chinese. Suggests modifications of and additions to the existing role operators and the accompanying software to overcome these problems

- Abstract
- Capability and capacity in handling the topology of a special subject information field has made infomapping techniques and systems instrumental in information searching, monitoring and navigation. Applying the technique to communication networks can reveal the intellectual relationships among junior and senior researchers in the field, and can also show the continuing popularity of a particular researcher's citation record over time. Reports the use of Java in making a cartoon series of chronological maps based on citation analysis on a special subject field (nutrition and dietetics). The map making methods, Java programming, and statistical analysis of the map data are presented, and the advantage and significance of constructing Java maps in enhancing information retrieval discussed. Further technical developments in applying VRML to link together a 3-D spatial indexing system and a 2-D HTML Web site are suggested
