ABSTRACT In this study, the text information of academic papers (about 2.3 million) published by Japanese authors and patents filed with the Japan Patent Office (about 12 million) since 1990 are used for analyzing the relationship between science and technology. Specifically, a distributed representation vector using the title and abstract of each document is created, then neighboring documents to each are extracted using cosine similarity. A time trend and sector specific linkage of science and technology are identified by using the count of neighbor patents (papers) for each paper (patent). It is found that the number of patents with similar technical contents of paper decreased over time while the number of papers with similar contents of patent increased. This can be interpreted as meaning that first scientific papers advance the frontiers of science, and then technological progress (in the form of patents) follows, in fields where substantial scientific knowledge already existed. This paper proposes a new methodology of measuring science and technology linkage by using text information as a complement to traditional indicators based on non-patent literature citations of patents.
 

Prof. Kazuyuki Motohashi is a Professor of Department of Technology Management for Innovation (TMI) School of Engineering, the University of Tokyo, and is leading the Motohashi Laboratory that covers broad topics on innovation research from macro view on Japan's competitiveness to micro analysis of firm's technology management issues. Prof. Motohashi is also an editor of Research Policy (https://www.elsevier.com/journals/research-policy/0048-7333/editorial-board ). Prof. Motohashi has been the founding committee for the AIEA (Asian Innovation and Entrepreneurship Association: http://www.aiea-nber.org/0202 ) and chaired the AIEA-NBER Meeting in the past (http://www.aiea-nber.org/040202 ). He is also a faculty fellow of Research Institute of Economy, Trade and Industry (REITI). He received his PhD. Business and Commerce from Keio University, his MBA from  Johnson Graduate School of Management, Cornell University, and his M.Eng. and B.Eng in Civil Engineering from University of Tokyo. He had taken various positions at the Ministry of Economy, Trade and Industry of the Japanese Government, including executive deputy director of Research and Statistics Department, head of international public relations office at International Trade Bureau and deputy director of Planning Division of SME Agency. He had worked also for OECD from 1995 to 1998 as an economist at Economic Analysis and Statistics Division of Directorate for Science, Technology and Industry. (http://www.mo.t.u-tokyo.ac.jp/keireki/motohashi-cv20130410.htm ).

His research interest covers a broad range of issues in economic and statistical analysis of innovation, including economic impacts of information technology, international comparison of productivity, national innovation system focusing on science and industry linkages and SME innovation and entrepreneurship policy. He has published several papers and books on above issues.
