Requirements Validation Through Viewpoint Resolution.

Requirements modeling depends on having available the knowledge of what should be modeled. Acquiring, or eliciting, this knowledge is recognized to be a hard problem, and different suggestions have been made to address it. In this paper we examine one such approach-viewpoint resolution. It is based on the fact that software requirements can and should be elicited from different viewpoints, and that examination of the differences resulting from them can be used as a Way of assisting in the early validation of requirements. Our research proposes a language for expressing views from different viewpoints and a set of analogy heuristics to perform a syntacticly oriented analysis of views. This analysis of views is capable of differentiating between missing information and conflicting information, thus providing support for viewpoint resolution. We also present empirical evidence Of the effectiveness of these mechanisms. [ABSTRACT FROM AUTHOR]
