Datalog逻辑程序调用语义及其应用研究
Research on Call Semantic of Datalog Logic Program and its Application
【摘要】 提出Datalog逻辑程序调用语义和调用谓词,说明包含程序调用谓词的可更新U-Datalog程序的操作语义及其固定点语义。提出在有限分层调用情况下U-Datalog程序的通用评价(evaluation)算法。最后对Datalog程序调用语义在数字版权语言中的应用做了说明并给出示例。
【Abstract】 The paper firstly gave the call semantic and call predicates of datalog logic programs,and discussed the opera-tional and fixpoint semantics of U-datalog programs with call predicates.Then the algorithms that evaluate U-Datalog programs with call predicates under definite stratified calls were presented.Finally,applications of the call semantic of datalog programs in digital rights management were explained and demonstrated.
