摘要:

描述逻辑知识和动作库(KAB)是一种机制,用于提供关于感兴趣的领域的信息的语义丰富的表示,在描述逻辑知识库和动作方面,随着时间的推移改变这种信息,可能引入新的对象。我们求助于DL-Lite的一个变体,其中不强制执行唯一名称假设,并且可以断言和推断对象之间的相等性。动作被指定为条件效应集,其中条件基于对知识库(TBox和ABox)的认知查询,并且效应以新的ABoxes表示。在这种情况下,我们解决了验证的时间属性表示在一阶μ演算的一个变种与量化跨状态。值得注意的是,在受数据交换中弱非周期性概念启发的适当限制下,我们展示了验证的可判定性。

英文摘要:

Description logic Knowledge and Action Bases (KAB) are a mechanism for providing both a semantically rich representation of the information on the domain of interest in terms of a description logic knowledge base and actions to change such information over time, possibly introducing new objects. We resort to a variant of DL-Lite where the unique name assumption is not enforced and where equality between objects may be asserted and inferred. Actions are specified as sets of conditional effects, where conditions are based on epistemic queries over the knowledge base (TBox and ABox), and effects are expressed in terms of new ABoxes. In this setting, we address verification of temporal properties expressed in a variant of first-order mu-calculus with quantification across states. Notably, we show decidability of verification, under a suitable restriction inspired by the notion of weak acyclicity in data exchange.
