- 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
- 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.

- 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
- 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

- 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
- Defines information seeking as using information to satisfy one's needs. Traditionally, quantitative research has focused on objective information and the external behaviour of users, while the alternative paradigm in user studies focused on subjective information and the internal cognition of users. In the context of the paradigm shift, scholars are calling for supplementing quantitative approaches with qualitative approaches. Reviews the literature and presents theories and empirical studies on information needs and information seeking behaviour

- 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
- 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
