This article looks at the access to geographic information through a review of information science theory and its application to the WWW. The two most common retrieval systems are information and data retrieval. A retrieval system has seven elements: retrieval models, indexing, match and retrieval, relevance, order, query languages and query specification. The goal of information retrieval is to match the user's needs to the information that is in the system. Retrieval of geographic information is a combination of both information and data retrieval. Aids to effective retrieval of geographic information are: query languages that employ icons and natural language, automatic indexing of geographic information, and standardization of geographic information. One area that has seen an explosion of geographic information retrieval systems (GIR's) is the World Wide Web (WWW). The final section of this article discusses how seven WWW GIR's solve the the problem of matching the user's information needs to the information in the system.

Information systems are becoming more involved in politics due to the growth of the World Wide Web, electronic government, and the increasing digitization of information of all kinds. Many information management specialists lack knowledge and experience about how to deal with political aspects of information management, and consequently they are ineffective. This chapter shows how important political issues are to information managers and illustrates strategies that can be useful in dealing with political issues. I provide several examples of how inattention to the political aspects of managing information systems can result in problems and disasters. The chapter covers both internal and external politics. Information managers have to deal with many internal politically-charged tasks such as the structuring of information management, purchasing information systems, managing personnel in this era of digital communication, and struggles over the sharing of information within organizations. External information management issues are also becoming important such as demands for online accountability information, the development of websites, issues over access to information, and interorganizational issues including disputes over turf.

Web-based information systems (WBIS) aim to support e-business using IT, the World Wide Web, and the Internet. This chapter focuses on the Web site part of WBIS and argues why an easy-to-use and interactive Web site is critical to the success of WBIS. A dialogue act modeling approach is presented for capturing and specifying user needs for easy-to-use Web site of WBIS by WBIS analysis; for example, what users want to see on the computer screen and in which way they want to work with the system interactively. It calls such needs communicational requirements, in addition to functional and nonfunctional requirements, and builds a dialogue act model to specify them. The author hopes that development of the Web site of WBIS will be considered not only an issue in WBIS design but also an issue in WBIS analysis in WBIS development.

The World Wide Web (WWW) has become the most widely used platform for application development and information delivery. Web applications have evolved from static, read-only Web sites to current, collaborative, mobile, and pervasive information systems. Most companies are automating their core work flows using Web technologies; new businesses supported by the provision of complex Web services appear every day.
