Abstract

World Wide Web poses many challenges for designing effective information services and applications. Addressing these challenges requires good understanding of Web characteristics and their implications. In this presentation we focus on selected aspects of the Web that affect searching and navigation by the users. We offer our insights into the issues and present our preferred strategies for addressing them. We demonstrate prototype systems that illustrate our solutions and discuss system evaluations that we have conducted.
