Outline of Final Research Achievements

We examined whether the natural language processing using monetary policy documents could be detect changes in the stance of policy makers. In this study, we showed that changes in monetary policy stance can be detected mostly well using two methods, latent semantic analysis (LSA) and latent Dirichlet allocation (LDA). This research shows that it is possible to extract information on policy stance by using statistical natural language processing from monetary policy related documents.

Academic Significance and Societal Importance of the Research Achievements

これまで金融政策分野の自然言語処理分析は蓄積されてきた。一方で、単語の意味を事前に指定したり、ポジティブあるいはネガティブな意味を持つ単語を指定するなどの、言語に関する事前情報を与えずに、金融政策として解釈可能な意味を取り出すことができるかについて必ずしも明らかではなかった。本研究は、可能な限り事前情報を与えないとしても、金融政策関連文書から統計的自然言語処理の手法によって政策スタンスに関する情報を取り出すことができることを示した。
