Implementation of an efficient requirements-analysis supporting system using similarity measure techniques

As software becomes more complicated and larger, software engineer’s requirements analysis become important and uneasy activity. This paper proposes a requirements analysis supporting system that supports informal requirements analysis. The proposed system measures the similarity between requirement sentences to identify possible redundancies and inconsistencies, and extracts the possible ambiguous requirements. The similarity measurement method combines a sliding window model and a parser model. Using these methods, the proposed system supports to trace dependency between documents and improve quality of requirement sentences. Efficiency of the proposed system and a process for requirement specification analysis using the system are presented.
