- Abstract
- Describes a study in which 6505 papers from 23 Chinese scientific and technical journals published in the 7 years from 1990 to 1996 were investigated. The quantity, languages and types of citations were analyzed and compared with data from the 1970s. In this way the progress of citations for Chinese scientific and technical journal literature can be seen

- 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
- 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
- In order to test the power of metadata on information retrieval, an experiment was designed and conducted on a group of 7 graduate students using the Dublin Core as the cataloguing metadata. Results show that, on average, the retrieval error rate is only 2.9 per cent for the MES system (http://140.136.85.194), which utilizes the Dublin Core to describe the documents on the World Wide Web, in contrast to 20.7 per cent for the 7 famous search engines including HOTBOT, GAIS, LYCOS, EXCITE, INFOSEEK, YAHOO, and OCTOPUS. The very low error rate indicates that the users can use the information of the Dublin Core to decide whether to retrieve the documents or not

- Abstract
- Attempts to circumscribe 'information' by means of etymology and the semantics of Chinese characters rather than the traditional way, and also to define several other terms related to information. Discusses the characteristics of information and its movement, and reviews some issues about information science. Information science recognizes information and uses it for making decisions and solving problems. Yi-Jeng (the Book of Changes), the oldest book about the world system, not only explains the relationship between human beings and the universe, but also focuses on how to recognize and use information to improve quality of life and avoid calamity. Derives some conclusions useful for the development of information science from Yi-Jeng. Also discusses the chaotic state caused by rapidly developing networks without a precise concept. Considers some desirable characteristics for the design of information service systems
