Web content is generally not tagged for easy determination of its instructional appropriateness and comprehensibility level. Our research develops an analytical model, using a group of website features, to automatically determine the comprehensibility level of a website. These features, selected from a large pool of website features quantitatively measured, are statistically shown to be significantly correlated to website comprehensibility based on empirical studies. The automatically inferred comprehensibility index may be used to assist the average person, interested in using web content for self-directed learning, to find content suited to their comprehension level and filter out content which may have low potential instructional value.http://www.bibsonomy.org/bibtex/2557594c19c464cf1e1f028b12a942f57/ewomantewomant2008-07-11T17:45:35+02:00usability methods usability_testing <span style="color:#555555;">Dennis <a href="http://www.bibsonomy.org/author/Wixon">Wixon</a> </span><em>interactions</em><em>10(4):28--34</em>(<em>2003</em>)Fri Jul 11 17:45:35 CEST 2008New York, NY, USAinteractions428--34Evaluating usability methods: why the current literature fails the practitioner102003usability methods usability_testing Practitioners who deal in the business world must find ways to keep up-to-date with best practices in the field and must apply them to their work in cost-effective ways. Research should help to define best practices, but often the worlds of research and of practice can seem too dichotomous. Recently, for instance, the fields of usability and user-centered design generally have seen considerable controversy about the relative effectiveness of different methodologies. In this column, Dennis Wixon argues that we need to look at whether we are evaluating methods by the appropriate criteria. He considers the growing body of literature on evaluation of methods unhelpful, or even irrelevant, to the practitioner. He argues that consideration of the factors that determine success of usability efforts in product development organizations will fundamentally change the terms of the debate. ---David A.

We have been developing auto-mated usability tools for several years, and here we describe a prototype service called InfoScent™ Bloodhound Simula-tor, a push-button navigation analysis system, which auto-matically analyzes the information cues on a Web site to produce a usability report. We further build upon previous algorithms to create a method called Information Scent Absorption Rate, which measures the navigability of a site by computing the probability of users reaching the desired destinations on the site. Lastly, we present a user study involving 244 subjects over 1385 user sessions that show how Bloodhound correlates with real users surfing for in-formation on four Web sites. The hope is that, by using a simulation of user surfing behavior, we can reduce the need for human labor during usability testing, thus dramatically lower testing costs, and ultimately improving user experience. The Bloodhound Project is unique in that we apply a concrete HCI theory directly to a real-world prob-lem. The lack of empirically validated HCI theoretical model has plagued the development of our field, and this is a step toward that direction.http://www.bibsonomy.org/bibtex/2f75197f05e9a6a0285e00dea659e88d3/ewomantewomant2008-07-04T16:54:35+02:00usability guidelines WebDesign automatisierte_evaluierung <span style="color:#555555;">Melody Y. <a href="http://www.bibsonomy.org/author/Ivory">Ivory</a> und Rodrick <a href="http://www.bibsonomy.org/author/Megraw">Megraw</a> </span><em>ACM Trans.

We present a longitudinal study of web site design from 2000 to 2003. We analyze over 150 quantitative measures of interface aspects (e.g., amount of text on pages, numbers and types of links, consistency, accessibility, etc.) for 22,000 pages and over 1,500 sites that received ratings from Internet professionals. We examine characteristics of highly rated sites and provide three perspectives on the evolution of web site design patterns: (1) descriptions of design patterns during each time period; (2) changes in design patterns across the three time periods; and (3) comparisons of design patterns to those that are recommended in the relevant literature (i.e., texts by recognized experts and user studies). We illustrate how design practices conform to or deviate from recommended practices and the consequent implications. We show that the most glaring deficiency of web sites, even for sites that are highly rated, is their inadequate accessibility, in particular for browser scripts, tables, and form elements.Empirically validated web page design metricshttp://www.bibsonomy.org/bibtex/25b96cc2b45e5d6233eafe59b2d842619/ewomantewomant2008-06-30T20:02:47+02:00usability imported automatisierte_evaluierung <span style="color:#555555;">Melody Y. <a href="http://www.bibsonomy.org/author/Ivory">Ivory</a> und Rashmi R. <a href="http://www.bibsonomy.org/author/Sinha">Sinha</a> und Marti A. <a href="http://www.bibsonomy.org/author/Hearst">Hearst</a> </span><em>CHI '01: Proceedings of the SIGCHI conference on Human factors in computing systems, </em><em>Seite53--60. </em><em>New York, NY, USA, </em><em>ACM, </em>(<em>2001</em>)Mon Jun 30 20:02:47 CEST 2008New York, NY, USACHI '01: Proceedings of the SIGCHI conference on Human factors in computing systems53--60Empirically validated web page design metrics2001usability imported automatisierte_evaluierung A quantitative analysis of a large collection of expert-rated web sites reveals that page-level metrics can accurately predict if a site will be highly rated. The analysis also provides empirical evidence that important metrics, including page composition, page formatting, and overall page characteristics, differ among web site categories such as education, community, living, and finance. These results provide an empirical foundation for web site design guidelines and also suggest which metrics can be most important for evaluation via user studies.http://www.bibsonomy.org/bibtex/2a3d75e78d10cd9091c612a458c117f52/ewomantewomant2008-06-30T19:42:45+02:00usability visualization usability_testing automatisierte_evaluierung evaluation <span style="color:#555555;">Pardha S. <a href="http://www.bibsonomy.org/author/Pyla">Pyla</a> und Jonathan R. <a href="http://www.bibsonomy.org/author/Howarth">Howarth</a> und Chris <a href="http://www.bibsonomy.org/author/Catanzaro">Catanzaro</a> und Chris <a href="http://www.bibsonomy.org/author/North">North</a> </span><em>ACM-SE 44: Proceedings of the 44th annual Southeast regional conference, </em><em>Seite620--625. </em><em>New York, NY, USA, </em><em>ACM, </em>(<em>2006</em>)Mon Jun 30 19:42:45 CEST 2008New York, NY, USAACM-SE 44: Proceedings of the 44th annual Southeast regional conference620--625Vizability: a tool for usability engineering process improvement through the visualization of usability problem data2006usability visualization usability_testing automatisierte_evaluierung evaluation We present Vizability, a usability engineering tool that is motivated by the variability of analysis processes and facilitates the analysis of existing problem data with the goal of process improvement. Usability engineers spend considerable resources performing usability testing and analyzing the resulting data, but their work is often limited to a single development effort or a small set of similar efforts. To extend the analysis process to multiple diverse efforts, it is necessary to categorize and store data in a consistent manner and have techniques for discovering patterns in that data. Our tool is designed to work with problem data that has been organized according to a hierarchical framework of usability concepts, which ensures consistency through completeness and precision. In addition, our tool helps engineers discover weaknesses in their process through exploratory browsing of a visualization of the tree structure and visual filtering based on cost, importance, and keywords.Automatic support for web user studies with SCONE and TEAhttp://www.bibsonomy.org/bibtex/2d25f53045787b37c6310a205a5ac1043/ewomantewomant2008-06-30T19:37:44+02:00usability usability_testing automatisierte_evaluierung <span style="color:#555555;">Hartmut <a href="http://www.bibsonomy.org/author/Obendorf">Obendorf</a> und Harald <a href="http://www.bibsonomy.org/author/Weinreich">Weinreich</a> und Torsten <a href="http://www.bibsonomy.org/author/Hass">Hass</a> </span><em>CHI '04: CHI '04 extended abstracts on Human factors in computing systems, </em><em>Seite1135--1138. </em><em>New York, NY, USA, </em><em>ACM, </em>(<em>2004</em>)Mon Jun 30 19:37:44 CEST 2008New York, NY, USACHI '04: CHI '04 extended abstracts on Human factors in computing systems1135--1138Automatic support for web user studies with SCONE and TEA2004usability usability_testing automatisierte_evaluierung This paper describes the concepts of TEA, a flexible tool that supports user tests by automating repetitive tasks and collecting data of user inputs and actions.

Recently, collaborative tagging has grown in popularity on the web, on sites that allow users to tag bookmarks, photographs and other content. In this paper we analyze the structure of collaborative tagging systems as well as their dynamic aspects. Specifically, we discovered regularities in user activity, tag frequencies, kinds of tags used, bursts of popularity in bookmarking and a remarkable stability in the relative proportions of tags within a given URL. We also present a dynamic model of collaborative tagging that predicts these stable patterns and relates them to imitation and shared knowledge.
