HanLP-Based Technology Function Matrix Construction on Chinese Process Patents
Abstract
The technology/function matrix is an essential method of patent analysis. This paper presents a semi-automated methodology to create technology/function matrix for Chinese process patents in any given domain. The approach adopts computer-aided algorithms in the process of extracting technology words, extracting function words, and generating technology/function matrix. The purpose of this paper is to increase the efficiency of building technology/function matrix and reduce the cost of manpower and time. The Chinese process patents in the domain of robot path planning art taken as an example to verify the methodology.
