[Objective] In order to achieve the micro drilling analysis of technical efficiency map and the recognition of specific patent involved in technical efficiency map. [Methods] This paper proposes a Patent Data Warehouse-based technical efficiency map mining method, which achieves the construction and multidimensional analysis of technical efficiency map by cleaning patent structured information and extracting feature words of unstructured information, combined with the Data Warehouse. [Results] The experiment results show that this method can achieve the objective fastly. [Limitations] However, if the amount of patent data is large, the star model used may reduce efficiency. And the patent feature extraction can't be automated. [Conclusions] This proposed method provides a new way for constructing and mining technical efficiency map.
