摘要

我们开发了一种基于模型的完整性语义，它对缺失的事实是开放的。我们通过实例化一个泛型三值完整性语义来实现这一点。我们首先概括一下后者。在此基础上，我们介绍并讨论了兼容owa的完整性语义的定义，该语义适用于可能缺少事实的数据库。我们还触及了一些开放的问题，超一致性方面和相关的最近的结果

An Integrity Semantics for Open World Databases

We develop a model-based integrity semantics which is open for missing facts. We do so by instantiating a generic three-valued integrity semantics. We first recapitulate the latter. Based on that, we introduce and discuss the definitions for an OWA-compatible integrity semantics which caters for databases in which facts are possibly missing. We also touch upon some open issues, paraconsistency aspects and a related recent result
