摘要

OWL中的模式语句的解释与关系数据库中的类似语句完全不同。如果要将这些语句解释为完整性约束(ic)，那么OWL的解释可能看起来令人困惑和/或不恰当。因此，我们提出了一种带有ic的OWL扩展，它可以捕捉关系数据库中ic背后的直觉。我们讨论了检查不同类型知识库的IC满意度的算法，并表明，如果满足约束，我们可以在回答广泛的积极查询时忽略它们。

Bridging the gap between OWL and relational databases

Schema statements in OWL are interpreted quite differently from analogous statements in relational databases. If these statements are meant to be interpreted as integrity constraints (ICs), OWL's interpretation may seem confusing and/or inappropriate. Therefore, we propose an extension of OWL with ICs that captures the intuition behind ICs in relational databases. We discuss the algorithms for checking IC satisfaction for different types of knowledge bases, and show that, if the constraints are satisfied, we can disregard them while answering a broad range of positive queries.

期刊介绍： The Journal of Web Semantics is an interdisciplinary journal based on research and applications of various subject areas that contribute to the development of a knowledge-intensive and intelligent service Web. These areas include: knowledge technologies, ontology, agents, databases and the semantic grid, obviously disciplines like information retrieval, language technology, human-computer interaction and knowledge discovery are of major relevance as well. All aspects of the Semantic Web development are covered. The publication of large-scale experiments and their analysis is also encouraged to clearly illustrate scenarios and methods that introduce semantics into existing Web interfaces, contents and services. The journal emphasizes the publication of papers that combine theories, methods and experiments from different subject areas in order to deliver innovative semantic methods and applications.
