摘要
Abstract
Integration of Answer Set Programming (ASP) and smart space solves the resource conflict problems in fixed precedence relationship.However,smart space is a context sensitive and dynamic environment.With the change of user's behavior in space,the information and service in the space should also be changed dynamically.The original context-aware framework based on ontology can only implement the reasoning of different ontology information,without considering the influence of environmental information for context-awareness.Thus,a context-aware framework is proposed based on ASP,perceiving the user's context ontology and the environment information dynamically and completing the user's context dynamic reasoning in space.Firstly,the ontology is used to describe the user's context information.Then,ASP is used to express the user's context reason rules in smart space,and default rules is introduced to decide the priority of the dynamic decision context response based ontology and the environment information.Finally,the solution of ASP is obtained,which is the result of the decision of the user's context,so as to help users realize the intelligent reasoning.The experiments show that this framework overcomes dynamic reasoning in space and achieves good effect.关键词
