Abstract : Information dissemination, accumulation and collection capabilities of web are assumed to change the world by new information distribution revolution. In this paper we first summarize basics of web information processing by emphasizing the differences between web and traditional information retrieval. As examples of web information systems, conceptual navigation using the word relationships extracted from web contents, and a geographic information system are shown. Web warehouse for performance improvement and database for functional enhancement are also discussed. Finally some additional important topics are discussed shortly.

Abstract : Given the growing number of contents available via the Internet, we usually encounter unknown words. However, it is often difficult to obtain descriptions for new words and technical terms in existing dictionaries and encyclopedias. The World Wide Web, which contains an enormous volume of up-to-date information, is a promising source to obtain new term descriptions. However, existing Web search engines often retrieve a number of extraneous pages and retrieved information is not organized as in hand-crafted encyclopedias. This paper describes a new searching site in which users can utilize the Web as an encyclopedia. Our site automatically compiles and updates an encyclopedia using Web pages, and has a number of useful retrieval functions.

Abstract : Japan Science and Technology Corporation (JST) released JST Link Center on September 2002 to enable the mutual linking between electoronic journals published in Japan and external electronic journals or bibliographic databases. The mechanisms of JST Link Center are described focus on the link master which is a core database of JST Link Center, JOI (JST Object Identifier) given to the contents registered into JST Link Center, and the automatic analysis of reference. Moreover, the reference linking image of JST Link Center is introduced as an example linking from J-STAGE to PubMed.

Abstract : This article outlines the salient features and current state of development of the Open Source GIS GRASS. We discuss the concepts and issues related to the development of GRASS that represents the only full fledged, multi-platform GIS available as OSS. Further, we highlight the potential of GRASS GIS in developing spatial data infrastructure and put forth a proposal for establishing a GRASS Consortium to support, nurture and accelerate furher developments.
