Abstract : Informatin Visualization is a technique for displaying large amount of data on a computer screen to enable users find a specific data or have good undrstanding of the whole data. Most of the information visualization systems can make users change various parameters interactively so that they can view the data from manyh different perspectives. In this article, we introduce various information visualization techniques developed so far, and introduce recent trends in the research area.

Abstract : We have been developing a system called “Subject World," which visualizes relations between concepts and enables users to operate them for subject retrieval. To date we have implemented a prototype system in which the user can browse and operate BSH4 subject headings and NDC9 index terms, and retrieve Osaka City University's OPAC. The prototype system helps users to browse information according to the user's thinking process, to input keywords for information retrieval, and to perform seamless searches by subject headings and by NDC9 using keywords. It also assists the user in acquiring knowledge about the subject, subject indexing and classification.

A study on patent citation visualization application of bibliometric concepts

Abstract : The present paper reviews the applicability of bibliometric approach to patent citation mapping and discusses the methodologies and data availability. The visualization techniques such as 2 step maps, Historiograph, and Research Fronts share common features that require the extraction of mappable elements and to set rules for mapping. Strong interrelations need to be found for effective data visualization. Patents and a journal article for the same invention are identified as a closely related literature group, from which bibliographic coupling and co-citation relationships are extracted for a mapping process. The citation map generated has shown strong interrelations within the literature group. In the same group, the high citation counts to the journal article and its interannual variability indicate the significance of the technology and rising science linkage.

Abstract : We propose a multimedia information retrieval model named “Panoramic Information Retrieval Model" and a multimedia information retrieval system, based on the model, named “MIRACLES (Multimedia Information RetrievAl, CLassification and Exploration System)". The system, which typically integrates semantic search by texts and visual search by images, enables “seeing and selecting information". We also describe some applications of MIRACLES including web search, digital camera image retrieval, digital document retrieval, video retrieval, technical drawing retrieval, and image mining.

Abstract : Visualization has shown to be an effective and invaluable method of decision-making in various fields, especially in fields where a large amount of data is to be analyzed and explored. In this paper, concepts of Visual Information Seeking originally developed by Shneiderman and Ahlberg et al. at the University of Maryland are surveyed. Visual Information Seeking mainly consists of three concepts : (1) Dynamic Queries, (2) Tight-Coupling, and (3) Starfield Display. In the second part, successful applications of the Visual Information Seeking as decision-making tool mainly in Pharmaceutical Research are discussed. The examples are illustrated with SpotfireR DecisionSiteＴＭ, a commercialized extension of FilmFinder.

Abstract : As the amount and diversity of information in the discovery, development, and business processes increased in various industries, it is no longer possible to process them by using the conventional list or a spreadsheet-based methods, and the new analysis approach is needed. Furthermore, in order to induce a strong hypothesis and to exclude a weak hypothesis, the integration across different information sources. Here, theoretical and technical basis which establishes “science of text visualization" is described. Especially, we focus on the visualizations of the integrated framework OmniViz, which provides common conceptual data models for multiple data type and overview of the entire data set with linked visualizations.

Adaptive presentation and adaptive navigation support of Web information services :
personal differences and learning effectiveness in hypertext learning
Eiichi KURAHASHI

Abstract : Owing to the development of World Wide Web technology, Web-based services such as library portals and information literacy tutorials in libraries of universities and corporations have increased. There are some learners who are difficult to adapt to hypertext while others are easily adapt to it. The reason why they can not adapt to hypertext is due to the cognitive differences of each learners, not due to the information processing skills or primary knowledge of them. Adaptive presentation and adaptive navigation support appropriate to cognitive differences of each learners are necessary, because hypertext structure impose burdens on learners of some learning styles and cognitive styles.
