In the characteristically requirements document (RD), the pronoun is scarcely used in RD in general. But if we would like to get the higher accuracy in analysis of RD 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 (NLRD) via natural language processing (NLP). In this paper, we propose the antecedent decision rule (ADR) to decide antecedent of pronoun from NLRD in Korean via NLP. Pronoun can be classified in personal pronoun and demonstrative pronoun. In the RD, a personal pronoun is almost not occurred so we are focused on antecedent decision for a demonstrative pronoun. The purpose of this paper is to describe the ADR that is used in postprocessing to reduce a burden of morphological analysis and parsing, so our approach can describe additional rules because every rule are applied in the postprocessing. We carried out an experiment with five brief NLRD added pronoun in.
