Abstract

This study proposes a new approach to identifying core technologies from the perspectives of co-occurrence, relatedness, and cross-impact based on patent co-classification information with consideration of the overall interrelationships among technologies. First, association rule mining is employed to derive the co-occurrence, relatedness, and cross-impact indexes and three technological matrixes are constructed. Second, the analytic network process is conducted to produce importance values of technologies for three perspectives with consideration of their direct and indirect impacts. Finally, data envelopment analysis is applied to identify priorities of technologies. The proposed approach can be utilized for technology monitoring for both technology planning of firms and innovation policy making of governments.
