| Sumario: | The KAOS (Knowledge Acquisition in Automated Specification) goals diagram is one of the most important diagrams during software requirements elicitation, that is to say, the first phase of a program's life cycle, since it helps stakeholders (users) to understand the importance of future software. In the studies in order to identify the traceability that should exist between natural language and the goals that have been identified to avoid inaccuracies between them was not possible. This paper presents a method for extracting and classifying goals in KAOS approach through the processing of textual requirements in Spanish. In this method, the phrases found in a text are broken down and a morphological and syntactical analysis is carried out for each phrase, using the classification of Spanish verbs as reference. Furthermore, morphosyntactic structures are defined which allow the goals to be typified and classified, based on the following types: (i) Maintain; (ii) Achieve; (iii) Cease and (iv) Avoid. This classification aims to list all of the goals and to represent them according to the KAOS goal model. This method will serve as a starting point for identifying the other components that make up the KAOS goal diagram and the semiautomatic rendering of said diagram. |
