GORO: uma ontologia sobre requisitos orientados a objetivos

Abstract

Correctly specifying requirements ensures that the right software is built to solve the right problem, and prevents errors that, if identified only in the development phase, can cost up to 90% more than if they were identified in earlier phases. Several approaches seek to improve the requirements elicitation process. Among them, the Goal-Oriented Requirements Engineering (GORE) offers advantages over traditional Requirements Engineering methods. Several approaches have been proposed since GORE emerged. However, almost none of these approaches were built on well-grounded artifacts or concerning the semantics of constructs. Thus, this work presents the Goal-Oriented Requirements Ontology (GORO), an ontology based on the Unified Foundational Ontology (UFO) and integrated with the Software Engineering Ontology Network (SEON). GORO intends to precisely define the semantics used by GORE approaches. GORO can be used, for example, for modeling languages analysis, as an interlanguage for model conversion and as a basis for building new GORE languages.
