- 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
- 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
- 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

- 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

- 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

- 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
- Identifies 6 types of searches on the basis of paudsing behaviour by using cluster analysis. The 6 types of search were highly associated with search fleuncy and the construction of a mental model. Examines learning during multiple searches on the basis of the 6 types. Finds that searchers gain more experience, increase their searching proficiency and become more fluent at searching while online. The changes of search level in multiple searches showed that most searchers moved towards greater fleuncy

- 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
