The Construction of Fuzzy Cognitive Map Classification Model Based on Relational Database

With the aim to facilitate cognitive and classification mining for multi-relationship system, the paper proposes a kind of FCM - TTFCM (Two-level Tree-type Fuzzy Cognitive Map). But how to construct TTFCM directly from relational database corresponding to the multi-relationship system is the key. A kind of calculation method to mine the structure of TTFCM and the initial state of hyper-node from the relational data resource is proposed, which lays the foundation for further weight learning.
