Abstract:

Modeling group organizations is the foundation for further research on group coordinative behavior. Most of existing organization models consider Agent organization or individual lowlevel instruction interaction, but concern little about the description of highlevel dynamic task interactions. In the paper, we propose a novel group organizational coordinative relationship model named GRNA (GroupRoleNormAbility) to describe the organizational coordinative relationship of agent groups. The GRNA model is based on the description logic of the task and it contains two submodels: cognition submodel and interaction submodel. The cognition submodel which provides accurate definitions of terms is built on domain ontology, while the interaction submodel based on the description logic of tasks reflects the collaboration between the tasks. Through the case study, we show that the GRNA model can describe norms and abilities of groups, provide powerful services of decidable deduction for the achievability of organization tasks, and express highlevel task interaction semantics of groups.
