Abstract:
In this paper, we presented an approach that finds the negation in software requirements, and scope of negation. Our approach works at different levels of parsing each level has its own importance. The main phase of our approach is the deep semantic parsing this phase is further divided into three phases that are classification of negation, argument detection and scope detection. First phase classifies the negated sentences into different types of negation as implicit negation, explicit negation, double negation and single negation. Argument detection finds arguments that are negated. The last phase finds the scope of negation the arguments that are actually negated by the negation signal. Experimental works shows that our approach scores better than earlier studies.
