表达性描述逻辑中一致内插和遗忘的基础
Foundations for Uniform Interpolation and Forgetting in Expressive Description Logics
摘要:
研究了描述逻辑ALC中的一致内插和遗忘问题。我们的主要结果是模型理论的一致插值和他们的存在性的bisimula- tions,严格的复杂性界决定一致插值的存在性,一种方法来计算插值时,他们存在,和严格的限制他们的大小。我们使用模型理论和自动机理论的方法,作为一个副产品,还提供了保守扩展的特征和决策程序的混合。
英文摘要:
We study uniform interpolation and forgetting in the description logic ALC. Our main results are model-theoretic characterizations of uniform inter- polants and their existence in terms of bisimula- tions, tight complexity bounds for deciding the existence of uniform interpolants, an approach to computing interpolants when they exist, and tight bounds on their size. We use a mix of model- theoretic and automata-theoretic methods that, as a by-product, also provides characterizations of and decision procedures for conservative extensions.
