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

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 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

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

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
