中文简介:
大规模本体的协同编辑对并发修改和强制解决提出了严格的要求。为了实现对并发修改的可靠处理,我们提出了基于alocking的方法,该方法确保独立事务同时在本体上工作,同时阻止可能影响其他事务的那些事务。在本体的逻辑上下文中,事务的依赖性和独立性不仅依赖于被修改的单个数据项,而且还依赖于从这些项中得出的推论。为了解决这个问题,我们利用本体的逻辑模块化并锁定本体的部分,这些部分共享正在进行的事务的推理依赖性。我们比较和评估模块化和锁定每个事务的整个本体的天真方法,并分析交易o?在计算锁所需的时间与同时运行事务所获得的时间之间。
课程简介: Collaborative editing on large-scale ontologies imposes serious demands on concurrent modifi cations and con ict resolution. In order to enable robust handling of concurrent modi cations, we propose a locking-based approach that ensures independent transactions to simultaneously work on an ontology while blocking those transactions that might in uence other transactions. In the logical context of ontologies, dependence and independence of transactions do not only rely on the single data items that are modifi ed, but also on the inferences drawn from these items. In order to address this issue, we utilize logical modularization of ontologies and lock the parts of the ontology that share inferential dependencies for an ongoing transaction. We compare and evaluate modularization and the naive approach of locking the whole ontology for each transaction and analyze the trade-o between the time needed for computing locks and the time gained by running transactions concurrently.
关 键 词: 协同编辑; 模块化; 运行事务
