Forty-two participants (22 males and 20 females) participated in the study. The results showed significant effects on the types of site maps used. It was found that participants found the correct answers more often, required less time, visited significantly fewer web pages, and required fewer clicks to complete the task when the site map was visible. However, it was found that the participants had a lower success rate in finding the correct answers when the site map had hyperlinks. In addition, the results showed significant performance differences among the three web sites and the effects of a site map were found to be more prominent for a larger web site.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

Maps of semantic similarity across textual and link similarity highlight the potential and limitations of lexical and link analysis for relevance approximation, and provide us with a way to study whether and how text and link based measures should be combined.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

There is much less research of application of learning styles in the new educational space, created by the Web. Moreover, authoring applications are scarce, and they do not provide explicit choices and creation of instructional strategies for specific learning styles. The main objective of the research described in this paper is to provide the authors with a tool which will allow them to incorporate different learning styles in their adaptive educational hypermedia applications. In this way, we are creating a semantically significant interface between classical learning styles and instructional strategies and the modern field of adaptive educational hypermedia.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

In this paper we describe an approach for building a system for efficiently monitoring changes to Web documents. This paper has three main contributions. First, we present a coherent framework that captures different characteristics of Web documents. The system uses the Page Digest encoding to provide a comprehensive monitoring system for content, structure, and other interesting properties of Web documents. Second, the Page Digest encoding enables improved performance for individual page monitors through mechanisms such as short-circuit evaluation, linear time algorithms for document and structure similarity, and data size reduction. Finally, we develop a collection of sentinel grouping techniques based on the Page Digest encoding to reduce redundant processing in large-scale monitoring systems by grouping similar monitoring requests together. We examine how effective these techniques are over a wide range of parameters and have seen an order of magnitude speed up over existing Web-based information monitoring systems.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

Residency training programs are under increasing pressure [1] to provide accurate and comprehensive evaluations of performance of resident physicians [2,3]. For many years, the Internal Medicine training program at NYU School of Medicine used a single standardized paper form for all evaluation scenarios. This strategy was inadequate as physicians train in multiple diverse settings evaluation of physicians in the intensive care unit is quite different from those in the general clinics. The paper system resulted in poor compliance by house staff and faculty in the completion of evaluations. In addition, the data being collected from the paper forms was of poor quality due to the non-specific nature of the questions. A committee was formed in 2001, which created a new strategy for evaluating the core competencies of house staff. Given the ubiquity of web accessible computers in the clinical and non-clinical areas of hospitals and the flexibility a computerized system would provide, a web-based evaluation system was designed and implemented. This system allows for on-the-spot evaluations tailored to the evaluator, evaluatee and the venue of the evaluation. During the 2002 residency year, data was collected on satisfaction and use of the system and compared with the previous paper evaluation.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

However, previous works on Flash are totally based on low-level features, which make it unpractical to build a content-based Flash search engine. To address this problem, our paper proposes expressive semantics for bridging the gap between low-level features and user queries. To smoothly incorporate expressive semantics into a search engine, an eigenvector-based model is devised to map a user query to expressive semantics with the aid of link analysis method. Our experiment results confirm that expressive semantics is a promising approach to understanding and hence searching Flash movies more efficiently.","PeriodicalId":409891,"journal":{"name":"WWW Alt.

Image data, such as photographs, logos, maps, illustrations, and decorated text, have been treated as sub-components of Web documents. However, we can alternatively recognize all Web pages as images on the screen. When a Web page is treated as an image, its HTML data is considered to be metadata which describes the image content. Taking such a viewpoint, we propose a new image-based hypermedia which we call continuous web. In our model, there is no distinction between Web images and other images such as photographs.Regarding everything on the Web as images leads us to consider a new style of browsing and navigating. We use the term scape-oriented browsing. We define a scape as a collection of continuously accumulated images. For example, whenever we walk in the real world, we can perceive and remember various forms of information through a scape process. Here, we describe new methods for scape-oriented browsing, such as see-through anchors, parallel navigation, and peripheral scape presentation. We have designed and implemented a prototype system based on our model. Our system offers continuous browsing and navigation to users. We explain our concepts and discuss the effectiveness and potential of this approach.","PeriodicalId":409891,"journal":{"name":"WWW Alt.
