- 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
- 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
- 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
- Library OPACs have long been the gateways between users and information. They present to users the achievements of library automation, and are the most widely available automated retrieval systems and the first that many user encounter. Current trends in OPAC design are toward a user oriented, individual information service which can meet the different needs of users with a variety of background and interests. Compared with the rather inactive, short term and general information service of conventional systems, this type of system focuses on active, long term and personalized service. Proposes a framework for the design of such an OPAC and discusses some recent developments in personalized information service

- 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

- Abstract
- A comparison of Chinese and Western bibliography reveals many differences. The purpose of traditional Chinese bibliography is to organize documents in a reasonable and valuable way, which essentially reflects the value and importance of human beings and their culture. Modern Western bibliography, on the other hand, attempts to order documents from the angle of form and philosophy, essentially reflecting the understanding of human culture, metaphysics and logic. Asserts that an understanding of the similarities and differences between the 2 approaches can contribute toward a reconsideration of the general theories, methods and techniques of bibliography

- 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.

- Describes a method of indexing the descriptors of the full text of document archives. Explains how the method organizes the thesaurus of descriptors, and mixes both keyword and index terms from the thesaurus. Presents a procedure for weighting descriptors and discusses the technical issues involved

- Abstract
- Attempts to investigate situational variables which can affect the results of relevance judgements, including computer experience, search experience, familiarity with search topic, preparation time, research objecttives, and research stages. The results show only the search experience will affect relevance judgements. Concerning research objectives, students writing term papers yield less relevance odds but a higher precision rate. concerning research stage, searchers in the early research stage yield more relevance odds and a higher precision rate

- 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
- A review of studies related to the information needs and communication behaviour of scientists which aims to explore the factors that influence their needs and methods of problem solving. Particular work environments affect needs. Information seeking and basic requirements are comprehensiveness, precision and availability. convenience of information access has a direct effect on the efficiency of a scientist's research but a lack of confidence in applying the solutions to information problems which are employed by librarians limits scientists to the more traditional ways of finding information in libraries. An awareness of this should lead librarians to improve collections and user services for the benefit of scientists and thus win their trust
