A Database Summarization Method using Fuzzy Concept Hierarchies and Fuzzy Linguistic Terms

摘要

Data summarization is a useful way to help understand and analyze large volume of data. This paper proposes a new summarization method that uses fuzzy domain knowledge for generalization of attribute values. The method follows the attribute-oriented induction approach and uses fuzzy concept hierarchies for nominal attribute generalization and uses fuzzy linguistic terms for numeric attribute generalization. The use of fuzzy concept hierarchies and fuzzy linguistic terms helps to produce comprehensive summary for databases. In addition, it presents some experiment results to show the applicability of the proposed summarization method.
