Artificial Intelligence Lab, Department of MIS, University of Arizona / Competitive Intelligence (CI) aims to monitor a firm’s external environment for information relevant to its decision-making process. As an excellent information source, the Internet provides significant opportunities for CI professionals as well as the problem of information overload. Internet search engines have been widely used to facilitate information search on the Internet. However, many problems hinder their effective use in CI research. In this paper, we introduce the Competitive Intelligence Spider, or CI Spider, designed to address some of the problems associated with using Internet search engines in the context of competitive intelligence. CI Spider performs real-time collection of Web pages from sites specified by the user and applies indexing and categorization analysis on the documents collected, thus providing the user with an up-to-date, comprehensive view of the Web sites of user interest. In this paper, we report on the design of the CI Spider system and on a user study of CI Spider, which compares CI Spider with two other alternative focused information gathering methods: Lycos search constrained by Internet domain, and manual within-site browsing and searching. Our study indicates that CI Spider has better precision and recall rate than Lycos. CI Spider also outperforms both Lycos and within-site browsing and searching with respect to ease of use. We conclude that there exists strong evidence in support of the potentially significant value of applying the CI Spider approach in CI applications.

The World Wide Web provides the capability of delivering multi-media presentations to a wide audience. This thesis details the design and development of the site Psychoacoustical demonstrations and experiments at McGill University: it discusses site organization, selection of materials and development methods. In order to evaluate the utility of the site, site usage data, feedback from readers and data from experiments are analyzed and discussed. The thesis examines the success of the site in attracting a wide audience and holding its attention, as course material, in gathering data from psychoacoustical experiments, and in obtaining feedback from readers. Suggestions for future sites of this type are included. / The test of the thesis should be read in conjunction with experiencing the World Wide Web site at http://www.music.mcgill.ca/auditory/Auditory.html.

End-users tend to lose their way in the maze of information within hypertext. Much work done to address the "lost in hyperspace" problem is reactive, that is, doing remedial work to correct the deficiencies within hypertexts because they are (or were) poorly designed and built. What if solutions are sought to avoid the problem? What if we do things well from the start? This thesis reviews the "lost in hyperspace" problem, and suggests a framework to understand the design and usability issues. These issues cannot be seen as purely psychological or purely computing, they are multi-disciplinary. The proactive, multi-disciplinary approach undertaken in this thesis is drawn from current technologies in sub-disciplines of hypertext, human-computer interaction, cognitive psychology and software engineering, and they include investigations into: " good design principles and guidelines for the building of hypertexts in the first place; " task analysis and user modelling techniques for end-users' tasks to be carefully defined; " effective hypertext structures to ensure usability of hypertexts; and " designer tools to create hypertexts with a reduced tendency for the "lost in hyperspace" problem to arise. To demonstrate these ideas, this thesis presents HyperAT, a hypertext research authoring tool, developed to help designers build usable web documents on the World Wide Web. The World Wide Web is chosen as a hypertext example since it is the most widely used and largest hypertext system ever. The approach taken in HyperAT is novel: multi-disciplinary approaches are integrated and implemented with a practical authoring tool. Evaluation of HyperAT indicates that it does address the "lost in hyperspace" problem, particularly for the World Wide Web by: (i) helping designers manage the complexity of the design and validation processes; and (ii) helping hypertext end-users navigate hypertexts produced by HyperAT without getting "lost".

This paper concentrates on the Worldwide Web (WWW) as a medium and also looks into Internet advertising which has various forms of delivering messages on the Web. From an examination of a review of the literature on the Web medium, three topics are discussed. The original and beneficial work presented by Hoffman and Novak (1996) that drew a model WWW communication compared with traditional communication. Next, Sepstrup's criteria (1991 cited in Thomsen, 1996) are used to contrast and compare traditional media and the Web medium. The differences are manifestly pointed out in terms of reach, selectivity, feedback, information capacity and costs. Measuring the effectiveness of media is one important topic of the Web medium that researchers take into consideration nowadays. Measures of the Web medium are clarified in two different approaches which are adopted from traditional media: communication effectiveness and sales effectiveness. / In relation to Internet advertising, there are two more topics to be reviewed. First, various forms of Internet advertising are classified from the most popular to the least. The distinctive characteristic of each form is also revealed. Second, the benefits of Internet advertising to marketing communication are posited. The paper looks into the contribution of Internet advertising to marketing objectives that are communication-oriented and action-based. Upon examining the communication-oriented objective, four key benefits: awareness, attitude, trust and loyalty are revealed. Click-through and sales volume are key benefits of the action-based objective. / Thesis (DBA(DoctorateofBusinessAdministration))--University of South Australia, 2006

This thesis is devoted to a component model for Web application and the corresponding tools for its development. The model is described after the review of various existing Web application development methods and models. A case study is also provided to support the analysis. -- abstract / Thesis (PhD)--University of South Australia, 2003.
