Identifying Quality Knowledge
With the advance of Web techniques, individuals and organizations can make use of low-cost information and knowledge on the Internet when carrying out data mining for applications. However, information from different datasources is often untrustworthy, contradictory, fraudulent, and even potentially dangerous to applications. Therefore, the discovery of reliable knowledge from different data-sources (databases or datasets) has become a critical task in multi-database mining research. In this chapter, a data-source is taken as a knowledge base (From our local pattern analysis, this assumption is reasonable.). A framework is thus presented for identifying quality knowledge from different data-sources.
