Usability analysis and visualization of Web 2.0 applications
2008
Nowadays companies and home users use Web sites offering services ranging from Web sites up to complex Web applications. Often the ergonomics of these applications remains unconsidered and they turn out to be hard to use. In order to examine the usability from within the Web applications, information about the usage of the application is collected. The techniques that have been used in the past for Web 1.0 are no longer adequate. Ajax programs (Web 2.0) are more flexible and require other techniques. This paper shows techniques for collection, analysis, processing and visualization of data for Web 2.0 applications.
Readability and the Web
2012
Readability indices measure how easy or difficult it is to read and comprehend a text. In this paper we look at the relation between readability indices and web documents from two different perspectives. On the one hand we analyse how to reliably measure the readability of web documents by applying content extraction techniques and incorporating a bias correction. On the other hand we investigate how web based corpus statistics can be used to measure readability in a novel and language independent way.
A tool to estimate usability of Web 2.0 applications
2009
Nowadays, companies and home users use websites offering services ranging from web sites up to complex web applications. The ergonomics of these applications often remain unconsidered and the applications turn out to be hard to use. In this paper, a tool is presented to facilitate the examination of usability. Web 2.0 applications in particular are supported, because they are more flexible and require other techniques than traditional web applications. The paper explains how to collect, analyze, process and visualize usability data for Web 2.0 applications.
Filtering usability data with reference to behavior
2011
No company can stay in business without having a "useful" web presence. The question is how usefullnes can be achieved. Usefullnes in this sense is how attractive and useful it is for the visitors. This can be done by observing the visitors' behavior. Doing this through interviews and observation of users in their living rooms is expensive and in many cases even impractical. So, other means need to be found. This paper presents a tool for the evaluation of usefulness of a web presence by extracting and analyzing information out of its log files. The information extraction can be refined using a set of filters which can be arbitrarily combined by the usability engineer responsible for mainta…
Estimating web site readability using content extraction
2009
Nowadays, information is primarily searched on the WWW. From a user perspective, the readability is an important criterion for measuring the accessibility and thereby the quality of an information. We show that modern content extraction algorithms help to estimate the readability of a web document quite accurate.
