Among all info structures which are these days on hand, sites are certainly those having the widest strength viewers and the main major impression at the way of life of individuals. sites give a contribution mostly to the knowledge society: they supply viewers with a wide array of prone and data and make allowance them to accomplish numerous initiatives with no previous assumptions approximately their laptop literacy. sites are assumed to be obtainable and usable to the widest attainable viewers. therefore, usability has been well-known as a serious luck issue for websites of each sort. past this common popularity, usability nonetheless is still a thought that's not easy to understand. Summative review tools were brought to spot capability usability difficulties to evaluate the standard of websites. notwithstanding, summative review continues to be restricted in effect because it doesn't inevitably carry optimistic reviews to website designers and builders on find out how to resolve the usability difficulties. Formative assessment tools were brought to handle this factor. evaluate continues to be a procedure that's tough to force and practice, whereas its power effect is perhaps maximal for the advantage of the ultimate person. This complexity is exacerbated while websites are very huge, possibly as much as a number of thousands of pages, hence resulting in a state of affairs the place eval­ uating the website is sort of very unlikely to behavior manually. as a result, many makes an attempt were made to help overview with: • types that seize a few features of the website of interest.

2 Method Type There is a wide range of evaluation methods within the testing, inspection, inquiry, analytical modeling, and simulation classes. Rather than discuss each method individually, one or more related methods are grouped into method types, which typically describe how an evaluation is performed. Chapters 3-7 present these method types. 3 Automation Type We adapt Balbo's automation taxonomy (described in Section 1) to specify the aspect of an evaluation method that is automated: none, capture, analysis or critique.

For additional assessments of some of the guideline review tools that we discuss in this chapter, we refer the reader to Chapters 11 and 12 in Part III. 2. Structural Analysis of Web Pages and Sites The Rating Game [Stein, 1997] is an automated analysis tool that attempts to measure the quality of web pages using a set of easily measurable features.

Number of sessions, percentage of site visitors, and keywords that characterize the group). Unlike other data mining approaches, LumberJack considers the content on web pages, the structure of the site, and the log file data in its clustering algorithms [Heer and Chi, 2002a]. The authors have shown through several empirical studies that the clustering approach yields good results (99 percent accuracy in some cases) and that LumberJack can help to inform site improvements. AWUSA (discussed in Section 3) takes a related approach to web usage mining, in that it considers the web site's structure and the evaluator-specified tasks in its analysis of usage patterns.
