本文讨论了在一个规则使能的语义Web中的物化本体的增量维护。物化允许通过显式化由本体的语义所认可的隐式蕴涵来加速查询处理。从而将本体推理的复杂性从查询时间转移到更新时间。我们假设，物化技术往往是重要的，以实现一个可扩展的语义Web，因为读访问本体是占主导地位的。物化的核心是维护技术，允许增量更新物化时发生的变化。我们提出了一种新的解决方案，允许科普规则和事实的变化。为了实现这一点，我们扩展了一个已知的方法，在演绎数据库中的视图的增量维护。我们展示了我们的技术可以用于广泛的现有Web本体语言，如RDF/S和子集的OWL，并提出了第一次评估。
This paper discusses the incremental maintenance of materialized ontologies in a rule-enabled Semantic Web. Materialization allows to speed up query processing by explicating the implicit entailments which are sanctioned by the semantics of an ontology. The complexity of reasoning with the ontology is thereby shifted from query time to update time. We assume that materialization techniques will frequently be important to achieve a scalable Semantic Web, since read access to ontologies is predominant. Central to materialization are maintenance techniques that allow to incrementally update a materialization when changes occur.We present a novel solution that allows to cope with changes in rules and facts. To achieve this we extend a known approach for the incremental maintenance of views in deductive databases. We show how our technique can be employed for a broad range of existing Web ontology languages, such as RDF/S and subsets of OWL and present a first evaluation.
