Chapter III Generalization Data Mining in Fuzzy Object - Oriented Databases

In this chapter, we consider the application of generalization-based data mining to fuzzy similarity-based object-oriented databases (OODBs). Attribute generalization algorithms have been most commonly applied to relational databases, and we extend these approaches. A key aspect of generalization data mining is the use of a concept hierarchy. The objects of the database are generalized by replacing specific attribute values by the next higher-level term in the hierarchy. This will then eventually result in generalizations that represent a summarization of the information in the database. We focus on the generalization of similarity-based simple fuzzy attributes for an OODB using approaches to the fuzzy concept hierarchy 86 Angryk, Ladner, & Petry Copyright © 2005, Idea Group Inc.

Then consideration is given to applying this approach to complex structurevalued data in the fuzzy OODB.
