It is purposed in this paper to improve the retrieval cffect~venebs through the use of the seman-- t r knowledge of search terms in a computerbased search system. This study is developed it1 three stages include the experimentation of index terms or1 the probab~listir model, indexing with relational operators, and knowledgebase design. The sl~bject experimerltrd is the specific fklds of Chemical Engineering, ' Fluid Flow' and 'Combustion: As for the system ~rnplementatlon. two kinds of search method a r e done. Orie is to search terms related to one specialty word, the other is to retriele the articles based or1 the gueries.

The purpose of this study is to identify the relationships among information search activities, of which perceived risk, cognitive dissonance, and involvement play a role. A survey of 155 students who have a recent experience on information search activities. Total six hypotheses the research already reported on information search effort, thereby giving decision maker a richer understanding of information search behavior.

This study analyzed the effect of the cognitive style of field dependence/independence to the information-seeking behaviors of 250 undergraduate students. The cognitive style of field dependence/ independence was examined by Group Embedded Figure Test (GEFT), information-seeking behaviors were examined by information-seeking performances, and survey for information-seeking behaviors. As a result of the analysis, the cognitive style of field dependence/independence affected items of information-seeking performances except one item among items set in this study. The cognitive style, the cognitive characteristics acting in the process of cognitive activity affected the actual activities of information-seeking behaviors. The cognitive style of field dependence/independence affected the seeking process except the results of seeking and general information-seeking behaviors in the areas of information-seeking behaviors. Therefore, the study of cognitive style can be effective in the seeking process areas of information-seeking behaviors.

This study explored factors affecting consumer's external information search effort on online shopping malls through three approaches(cost-benefit approach, psychological motivation approach, and web-site theory approach) respectively, and designed the integrative model through searching the relationships among them. In this study search motivation are designed to be explained by search benefit and search cost that are explained by factors related to the web site and search efforts are designed to be explained by search benefit, search cost and search motivation. The results from our empirical research showed that search motivation, search benefits and prior knowledge on online shopping malls have a direct effect on consumer external information search effort. On the other hand, it was verified that the search motivation was affected by search benefits and purchase involvement, and the search benefits are directly influenced by purchase involvement, constructive simplicity, search convenience and trust. In addition, purchase involvement, time press, constructive simplicity and search convenience had direct effects on the search cost.

The primary purpose of this study is to verify the difference of behavioural characteristics between the subject specialists and professional searchers in searching full-text databases. The major findings and conclusions from this study are summarized as follows. Analyses of Search questions(the degree of understanding with search questions, the degree of difficulty in selecting terms, and the degree of expectation of search results), search processes(the number of search terms used, the number of Boolean operators and qualifiers used, the number of documents browsed and the search time(the connecting time, time to spend per one output document, time to spend per one relevant output document) and search results(the searching efficiency(the number of relevant documents, the ,recall ratio and the precision ratio), the search cost(the total search cost. the search cost per one output document and the search cost per one relevant output document) and the degree of satisfaction with search results) are significantly different between the subject specialists and professional searchers in searching full-text databases.

This study focuses on the characteristics of information seeking behavior through the casual interactions which are regular contacts with others as information sources in the context of ELIS. Qualitative data were gathered using semi-structured one-to-one interviews with 9 wild-goose mothers in order to investigate the casual interactions. We identified information needs, patterns and characteristics of information seeking behavior through the casual interactions and the major interpretative repertoires.

This study empirically investigates the effects of information search on new product development (NPD) process and performance with a sample of 82 NPD projects in 5 firms. The information search is consisted of general sources, internal sources, and external sources. The performance is consisted of technological and market performance. Findings show that information search from internal sources increases the technological knowledge of the NPD team, and information search from external sources increases the market knowledge of the NPD team. The technological and market knowledge of the NPD team increases its technical performance respectively. Only the market knowledge of the NPD team increases its market performance. Overall, the technological knowledge of the NPD team fully mediates the relationship between the information search from internal sources and its technical performance. The market knowledge of the NPD team fully mediates the relationship between the information search from external sources and its technical performance, and the relationship between the information search from external sources and its market performance. There is no other significant mediation relationships between the information searches and the performances. Implications of the research findings are discussed, and recommendation for future research are provided.

It is widely known that the dynamic optimal path algorithm, adopting real-time path finding, can be supporting an optimal route with which users are satisfied economically and accurately. However, this system has to search optimal routes frequently for updating them. The proposed concept of optimizing search area lets it reach heuristic optimal path rapidly and efficiently. Since optimal path should be increased in proportion to an distance between origin and destination, tremendous calculating time and highly efficient computers are required for searching long distance journey. In this paper, as a result of which the concepts of partial solution and representative path are suggested. It was possible to find an optimal route by decreasing a half area in comparison with the previous method. Furthermore, as the size of the searching area is uniform, comparatively low efficient computer is required for long distance trip.

The research was conducted to investigate factors that facilitate users' finding books by analyzing classifications in public library and bookstore. This research was based on the assumption that the users' needs and information behaviors are similar in both public library and bookstore. The main purpose of this study is not to recommend classifying public library collections the way a bookstore does, but to figure out what makes the users' book finding more convenient by analyzing the classifications. To carry out the research, users' book finding in public library and classifications of public library and bookstore are analyzed. Then, a survey was conducted to investigate users' book finding behaviors, degree of convenience in finding books according to different classifications and the causes of the convenience. The results of the research showed that bookstore's classification was more convenient for the users in finding books.
