Web-based information systems, such as search engines, news
portals, electronic markets and community sites, provide access to
information originating from numerous information providers. The
quality of provided information varies as information providers
have different levels of knowledge and different intentions. Users
of web-based systems are therefore confronted with the increasingly
difficult task to select high quality information from the vast
amount of Web-accessible information. How can information systems
support users to distinguish high quality from low quality
information? Which filtering mechanisms can be applied? How can
filtering decisions be explained to the user? The book gives an
overview about information quality assessment in context of
web-based systems. Afterwards, a quality-driven information
filtering framework is developed. The framework allows information
consumers to apply a wide range of different filtering policies. In
order to facilitate the information consumers' understanding of
filtering decisions, the framework generates explanations why
information satisfies a specific policy. The book targets Web
developers who need to handle information quality problems within
their applications as well as researchers working on the topic.
