- 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
- 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
- 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
- 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
- Since most popular commercialized systems for full text retrieval are designed with full text scaning and Boolean logic query mode, these systems use an oversimplified relationship between the indexing form and the content of document. Reports the use of Singular Value Decomposition (SVD) to develop a Cluster Indexing Model (CIM) based on a Vector Space Model (VSM) in orer to explore the index theory of cluster indexing for chinese full text documents. From a series of experiments, it was found that the indexing performance of CIM is better than traditional VSM, and has almost equivalent effectiveness of the authority control of index terms

- 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
- 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
- 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
- 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
- Notes the difficulties of searching over heterogeneous information sources where query languages are not unifrom. Presents a model where Boolean queries are composed in one rich front end language. For each query and target source, the query is transformed into a subsuming query that can be supported by the source but may return extra documents. The results are then processed by a filter query to yield the correct results

- 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.
