Knowledge identification from requirements specification

Abstract

One of the main artifacts in Requirements Engineering is the Requirements Specification (RS). Throughout the life cycle of the RS arises the need of extracting knowledge in order to facilitate communication with stakeholders. However, this process is not usually efficient. In the different proposals for the representation of an RS conflicts often arise, due to coupling and redundancy of requirements. The Aspect-Oriented paradigm provides principles to address a multidimensional modeling to avoid these conflicts. Knowledge-Engineering is proposed to provide a model of the knowledge needed to allow an efficient extraction of knowledge from the requirements by ontologies. An experimental study has been developed to assess its efficiency when compared with classical methods.
