It is critical to detect and correct information errors effectively to achieve higher data quality in many applications. Most existing techniques only use the intrinsic information to detect and correct a database, provided that data is adequate and well-structured. These techniques will not work properly if there is no sufficient data available. Integrating the information from external sources, like the World Wide Web (WWW), can help us overcome the shortcomings of existing techniques to a great extent. In this paper, we introduce our on-going work that is capable of detecting and correcting data errors in a database by integrating external information from the WWW. The goal of our research is to pursuit another effective way to enhance information quality.
