中文简介: | 对可伸缩查询应答的需求经常迫使语义Web应用程序使用不完整的OWL 2 reasoners,这在某些情况下无法导出查询的所有答案。 这显然是不合需要的,并且在某些应用中甚至可能是不可接受的。 为了解决这个问题,我们研究了“修复”本体T的问题,即计算本体R,使得当与T [R]一起使用时,T不完整的推理器变得完整。 我们确定T上的条件和使这成为可能的推理器,提出了一种计算R的实用算法,并提出初步评估,表明在一些实际情况下,修复是可行的,可以计算,尺寸合理,并且不显着 理性推理表现。 |
课程简介: | The need for scalable query answering often forces Semantic Web applications to use incomplete OWL 2 reasoners, which in some cases fail to derive all answers to a query. This is clearly undesirable, and in some applications may even be unacceptable. To address this problem, we investigate the problem of "repairing" an ontology T |that is, computing an ontology R such that a reasoner that is incomplete for T becomes complete when used with T [R. We identify conditions on T and the reasoner that make this possible, present a practical algorithm for computing R, and present a preliminary evaluation which shows that, in some realistic cases, repairs are feasible to compute, reasonable in size, and do not significantly affect reasoner performance. |
