Knowledge maps integration approach based on document instance mapping

To realize the integration among integrated knowledge map points, a method to integrate knowledge maps by using document knowledge instances mapping was presented. The knowledge map of product development was classified as the concept knowledge map, the process knowledge map and the expert knowledge map. Based on the classification, the integrated knowledge map-based development knowledge organizational framework was proposed. The relevance of node instance sets which belonged to different maps was calculated by document instance matching method. Combined with the constraints, the nodes were connected, and three types of knowledge resources on a knowledge node were integrated methodically. An example was used to demonstrate the feasibility of proposed method.
