Technical trend analysis for research papers and patents : Patent Mining Tasks of the Seventh and Eighth NTCIR Workshops

Abstract

This paper introduces the Patent Mining Tasks of the Seventh and Eighth NTCIR Workshops and the test collections produced in these tasks. The task's goal is the creation of technical trend maps from a set of research papers and patents in a particular research field. In this paper, we explain two subtasks: (1) research papers classification and (2) technical trend maps creation, which are conducted in the Patent Mining Task. We also show a system that classifies research papers into the International Patent Classification (IPC) system, which is a global standard hierarchical patent classification system.
