【摘要】 本体的协同构建任务较为复杂,通常需要多个开发人员协同工作才能完成,而当前的本体构建工具和方法缺乏对本体协同构建的支持。为此,提出一种基于细分锁的并发控制方法。对节点的操作进行划分,将最小粒度锁定到节点的操作单元上;对锁的类型进行细分,针对不同的操作对象加上不同的锁,同时设计细分加锁算法。应用结果表明,该方法能有效提高协同开发的并发性和集成性。更多还原

【Abstract】 Collaborative construction of ontology is a very complicated task.It often requires many developers to work collaboratively.However,current ontology development tools and methods are lack of supporting to it.Therefore,a concurrent control method based on lock subdivision is proposed,which divides nodes into some smaller units according to the operations to nodes,making the minimal granularity of lock be the operation unit of nodes,and also subdivides the lock,according to the operation type,locks the correspondent unit.Furthermore,the locking algorithm is designed.Application result shows that this method can effectively improve concurrency and integration of the collaborative development.更多还原
