Companies handle many kinds of contracts such as sales agreements and basic sales transaction agreements. During drafting, they ask their own legal department or advisory legal firm for a contract review. Legal officers in these organization provide comments on (1) an unfavorable term, (2) lack of a necessary term, (3) a typographic error, (4) an inappropriate use of legal terms, and so on, by referencing similar contracts. They conduct this inspection with their highly specialized knowledge and experience; however, we may face a shortage of manpower for contract review in near future because of birthrate decline and labor reform. Therefore, we develop a contract review support system that finds the issues above. We apply a rule-based solution for issues (1), (2), and (3) since many contract expressions and description rules are standardized. We apply a machine learning-based solution for issue (4) since using legal terms appropriately depends on context.
