Based on the basic concept of the goal lay of the requirement meta-modeling frame for network software(RGPS-G), this paper advanced a new formal method to guarantee its correctness. The importance of introducing the formal method into RGPS-G was discussed based on the characters of RGPS-G. Theorem proving and model checking had merged in this formal method. Simple formal normative language was used...
Formal methods have been widely used in computer science and being improved day by day. Towards finite relation models, this paper advances a new formal method used by sextuple based on symbolic logic. It can use simple formal normative language to depict the relation between the modules in model exactly. With logical reasoning, it can analyse the models with theorem proving and model checking. In...
UML has become the dominant modeling language in software engineering arena. In order to reduce cost induced by design issues, it is crucial to detect model-level errors in the initial phase of software development. In this paper, we focus on the formal verification of dynamic behavior of UML diagrams. We present an approach to automatically verifying models composed of UML state machines. Our approach...
Affective computing has been investigated by many to allow computers to respond to or react to human or user emotion. In this paper, a model of personality and emotion was proposed based on the architecture of a cognitive system. Considering the external and internal factors of a virtual agent, formalized description of the emotional model was built. Experiment results indicated that the emotion generated...
