MEASURING INFORMATION QUALITY IN THE WEB CONTEXT: A SURVEY OF STATE-OF-THE-ART INSTRUMENTS AND AN APPLICATION METHODOLOGY

摘要

Various powerful instruments exist today to evaluate information quality in the web context. They can be categorized into five types of tools, namely performance monitoring systems, site analyzers, traffic analyzers, web mining tools and survey tools (to generate opinion-based user feedback). The combined use of these tools can enable an organization to measure the multiple dimensions of information quality in the Internet or Intranet context. This however requires a clear methodology that is based on systematic sequential steps and on an information quality framework that outlines relevant measurement criteria. In this paper we show which information quality criteria can be measured with the help of these tools and we provide an overview on the most important of these instruments. We present the IQM-methodology to match information quality criteria with adequate measurement tools.
