Abstract:This paper explored a new method of recognizing the core R&D team of an institution in order to provide support for talents introduction of enterprises, industries and regions, as single talent introduction cannot meet the increasing demand of talents. Since traditional co-occurrence method has many drawbacks, we introduced and optimized FP-Growth algorithm of association rules mining to recognized core R&D team from patent data. Then, Changchun Institute of Optics, Fine Mechanics and Physics of CAS was selected as experimental subject to test the method's validity. Finally, an empirical study of CAS was conducted. Result of empirical study indicated that CAS has 7 core R&D teams, including Marine Biological Products Research Group from Institute of Oceanology of CAS and so on.
