A novel approach to discovering the pattern of customer

Practicing customer (owner) retention in construction management is very important. Despite existing the importance of owner retention in many projects, there is a lack of a comprehensive and effective approach to realize it fully. According to these conditions, intuitionistic fuzzy set theory, alpha-cuts, expert domain knowledge are employed to discovery the pattern of owner retention under the context of domain-driven data mining methodology in this paper. The proposed approach is not only expatiated by an example, but also is proved by the experiments. In short, the approach provides a route to guide the further research concerning owner retention.
