Abstract: Requirements are the basic building block for development of good product. Requirement analysis is one of the major steps to reduce complexity of developing product. Several automatic analysis methods have been proposed to improve the quality of requirement. Currently there is no technique available to reduce ambiguity caused by Lexical, Syntactic and Syntax ambiguities. In this paper we identify these ambiguities and reduce them to improve the quality of requirement.

Keywords: Requirement Specification, Lexical Ambiguity, Syntactic Ambiguity, Semantic Ambiguity.
