Researches on Software Requirements Elicitation Approach of the Aviation Electronics Systems based on Multi-ontology

Because of the increasing complexity of software systems as well as the more various types of R&D personnel of the workers, software development is going to a significant trend of knowledge intensification. In the field of knowledge engineering, an ontology is an explicit specification of a conceptualization. In this paper, the ontology method is used to construct the requirement knowledge framework and the various of requirement knowledge is expressed as a clear, complete and consistent hierarchical ontology concept and association, which is more conducive to knowledge sharing and reuse as well as reflects multiple viewpoints of stakeholders. Furthermore, the relevant content of the decomposition of the generalization ontology is added in the framework, which is divided into the structure ontology and action ontology. It makes up for the deficiency of undifferentiated knowledge composition representation of the generalization ontology. Besides, the concept of software requirement error pattern is proposed and integrated into the multi-ontology framework of requirement knowledge in a consistent form. Based on the framework, the domain requirement model and the application requirement model can be built. It can be adopted as the basis of the requirement elicitation activities to avoid errors and improve the quality and reliability of software products.
