Abstract

Frequent itemsets determine major characteristics of a transactional database. An arbitrary Boolean expression can be thought as a generalized form of a query. It offers important knowledge to an organization. It is important to mine arbitrary Boolean expressions induced by frequent itemsets. In this chapter, we have introduced the concept of generator of an itemset, and showed that every Boolean function can be synthesized by its generator. The concept of conditional pattern has been introduced in Chap. 2. We discussed a simple and elegant framework for synthesizing generator of an itemset and designed an algorithm for this purpose. Experimental results are provided on four different databases.
