Research Abstract

本研究の目的は、科学層、技術層それぞれの引用ネットワークの構造を分析し各層間の差異を分析することで、科学層では既に成果が存在するが技術層では未だ活発でない、産業として未開拓な技術領域の候補を早期に発見するための方法論構築を行うことである。平成22年度は、当初の研究計画通り、前年度に得た知見を基に、論文と特許間の意味的な関係性を測定する手法をネットワーク分析、自然言語処理を応用して実装し、改良した。具体的には、関係性を測定する際に用いる語句集合の選択方法を複数比較し、最もエキスパートの判断に近くなる語句集合の選択方法を選ぶ方法を提案した。また、他分野への展開として、これらの手法を太陽電池分野、二次電池分野、燃料電池等の主にエネルギー分野へ応用し、分野間の差異の比較を行った。最後に、これらの研究成果を、産業として未開拓な技術領域の候補を早期に発見する方法論を整理し、Journal of the American Society for Information Science and Technology、Technological Forecasting and Social Change、foresight等の主に情報科学、技術経営系の論文誌、IEEE International Conference on Industrial Engineering and Engineering Management 2010、Portland International Conference on Management Engineering and Technology 2010等の国際会議で発表した。
