有価証券報告書からのリスク文抽出の試み

抄録

Recognizing risks that are descriptive information is important to judge how companies manage their risks, that is, the consistency of the strategy when evaluating companies. So, in this research, risk is defined as "uncertainty of future results that can be obtained by taking actions", and we tried to extract the details of the risks recognized by each company from the text of the securities report. We also tried to classify the extracted risk based on their respective contents. The extraction method is investigating and classifying the expression patterns (possibly, etc.) used when expressing the content of risk, and using them as clues.
