我々は,研究者が技術動向を分析する作業を支援するシステムの構築を目指している.本稿では,その要素技術となる英語論文表題の構造解析手法を提案する.一般に英語論文表題の構造は日本語のものより複雑であるため,英語論文表題の構造解析は日本語の場合よりも解析精度が低い,という問題があった.そこで,日本語論文表題の構造解析結果と翻訳知識を組み合わせた,英語論文表題の構造解析手法を提案する.実験の結果,精度77.98%,再現率75.15%が得られ,提案手法の有効性が確認された. / We have been studying towards construction of a support system for technical trend analysis. In this paper, we propose a method for analyzing research papers' titles written in English, which is an elemental technology for the support system. Generally, structures of research papers written in English are more complicated than those in Japanese, and this degraded the performance of the analysis method for English titles in comparison with that for Japanese. To solve this problem, we propose a method for the English titles using the analysis results of Japanese titles and Translation Information. We conducted an experiment and found that our method obtained a precision of 77.98% and a recall of 75.15%
