[Objective] This study tries to identify competitive intelligence based on implicit correlated knowledge, aiming to help enterprises have upper hands in the fierce competition. [Methods] First, we constructed a knowledge system for competitive intelligence based on the metadata. Then we generated a network with the help of relationship among the attributes of these metadata. Finally we identifed competitive intelligencey through similarity analysis and merging multi-attributes. [Results] We successfully established a network for the properties of knowledge metadata from the enterprise’s financial and sales index, R&D ability and other resources. We identified the business ties based on the intelligence metadata of product HS, and merged the metadata of MGIS market planning. [Limitations] The proposed system could be improved with larger sample size. [Conclusions] This study solves the issues facing complex relation identification and intelligence analysis demands. It also benefits the competitive advantage evaluation, crisis warning, and decision making.
