An SAO ‐based text‐mining approach for technology roadmapping using patent information

Abstract

A technology roadmap (TRM) links technologies with a company's strategic objectives and so supports acquisition of required technologies in advance of needs. It is a powerful tool for strategic planning and technology management. Because technology is changing rapidly and market competition is fierce, the role of aTRMis becoming increasingly important. To support the role of aTRM, many firms and governments that use roadmapping are becoming interested in reducing costs while retaining objectivity duringTRMdevelopment. One suggestion to achieve these goals is to use the keyword‐based quantitative approach to creating aTRM, but the information provided by the approach is limited because of the characteristics of keyword information. To solve this limitation, this research uses the concept of ‘function’ to support quantitative analysis for developing aTRM. The concept of function can provide information on the uses and purposes of a technology. To represent a function, a subject–action–object structure is commonly used. The suggested approach allows research and development (R&D) managers to extend the views of product and technology during development of aTRM. In addition, by reducing the time required to develop aTRM, the proposed approach supports quick and accurate decision‐making byR&Dmanagers.
