Anaphora Resolution System for Natural Language Requirements Document in Korean

When a system is developed, Requirements Document is generated by requirement analysts and then translated to formal specifications by specifiers. If a formal specification can be generated automatically from Natural Language Requirements Document, system development cost and system fault from experts' misunderstanding will be decreased. Also, if we would like to get the higher accuracy in analysis of Requirements Document automatically, antecedent decision of pronoun is very important for elicitation of formal requirements (i.e. component, action, statement and parameters etc.) automatically from Natural Language Requirements Document via Natural Language Processing. Pronoun can be classified in personal and demonstrative pronoun. In the Requirements Document, the personal pronoun is almost not occurred so we focused on antecedent decision for a demonstrative pronoun. The final goal of this research is to generate automatically formal specifications from natural language requirements document using natural language processing to develop systems. For this, This paper, based on previous research [1], proposes the Anaphora Resolution System to decide antecedent of pronoun using Natural Language Processing from Natural Language Requirements Document in Korean.
