摘要
The increasing popularity of social networking makes the social network an important place for digital content dissemination and also brings new business models. The business application of social network needs a balance among these partially diverging interests of the involved parties: users, advertisers and the social network provider. So a contractual access control is needed to assure the three parties that the balance polices can be executed according to the predefined rules. The paper presents a new logic TS_u_Datalog to achieve the goal, a distributed logic incorporated with distributed temporal logic and active rules. The paper shows TS_u_Datalog is one of the most abundant and flexible datalog logic that can describe and execute contractual policies in the distributed and dynamic environment of social network. Firstly, the paper introduces the fundamental concepts, syntax and evaluation method of TS_u_Datalog. Secondly, application on digital content dissemination for social network is illuminated and a motivational example is presented to show the full-fledged temporal expressivity of the logic. Finally, a contrastive analysis is discussed and future works are planned.
