摘要翻译：
本体与非单调规则的集成在许多领域中变得越来越重要，例如语义网。为了解决这个问题，许多研究者提出了由本体（用一阶逻辑片段表示）和非单调规则组成的混合知识库的统一语义。这些语义在过去几年中已经成熟，但只为知识不需要演化的静态情况提供解决方案。在本文中，我们向解决混合知识库的动力学问题迈出了第一步。我们着重于知识更新，并考虑到信念更新、本体更新和规则更新的技术现状，我们表明当前的解决方案只是部分的，很难结合。然后对ABox规则更新的现有工作进行了扩展，为这种进化的混合知识库提供了一种语义，并研究了其基本性质。据我们所知，这是第一次为混合知识库提出更新算子。

英文摘要：
  The need for integration of ontologies with nonmonotonic rules has been gaining importance in a number of areas, such as the Semantic Web. A number of researchers addressed this problem by proposing a unified semantics for hybrid knowledge bases composed of both an ontology (expressed in a fragment of first-order logic) and nonmonotonic rules. These semantics have matured over the years, but only provide solutions for the static case when knowledge does not need to evolve. In this paper we take a first step towards addressing the dynamics of hybrid knowledge bases. We focus on knowledge updates and, considering the state of the art of belief update, ontology update and rule update, we show that current solutions are only partial and difficult to combine. Then we extend the existing work on ABox updates with rules, provide a semantics for such evolving hybrid knowledge bases and study its basic properties. To the best of our knowledge, this is the first time that an update operator is proposed for hybrid knowledge bases.
