A Systemic Method for Measuring Quality of Information on Weblog

The vast amount of information on the World Wide Web is created and published by many different types of providers. Unlike books and journals, most of this information is not subject to editing or peer review by experts. This lack of quality control and the explosion of web sites make the task of finding quality information on the web especially critical. Meanwhile new facilities for producing web pages such as Blogs make this issue more significant because Blogs have simple content management tools enabling non-experts to build easily updatable web diaries or online journals. On the other hand despite a decade of active research in information quality (IQ) there is no framework for measuring information quality on the Blogs yet. This paper presents a framework for calculating and ranking quality of information on the Weblog. The current framework includes qualitative and quantitative criteria. The quantitative criteria were calculated automatically and the qualitative criteria were obtained by voting in the framework. The results of data analysis collected by system log files revealed high correlations between the criteria.
