In this paper we propose a researcher history service for supporting prescriptive analytics services based on Researcher activities. In order to extract researcher activities, we have collected diverse resources from SNS, Web, NDSL and so on. Based on these resources, we extracted activities of researchers to propose a prescriptive analytics and tracking service. To achieve the goal of this service, we have identified researchers using their names and titles which are stored in diverse resources to merge and collect activities of a researcher. Our service compared with existed services that can provide descriptive services to researchers for helping analysis about researchers who could be involved in a role model group as a mentor. Through the proposed service, researchers can obtain strategies to go forward to a role model group and can certain history about activities of a researcher.
