数据库中的归纳逻辑程序设计:从Datasheet到DL +log

Inductive Logic Programming in Databases: from Datalog to DL+log

Università degli Studi di Bari(巴里大学)

Francesca A. Lisi

摘要:

在本文中,我们解决了一个问题,已经引起了数据库社区的注意,随着语义Web的出现,即本体论(和它们所传达的语义)如何帮助解决典型的数据库问题的问题,通过更好地了解KR方面相关的数据库。特别是,我们调查这个问题,从ILP的角度考虑两个数据库的问题,(i)的定义的意见和(ii)的定义的约束,为数据库的模式表示也通过本体。两者都可以重新表述为ILP问题,并可以受益于KR框架DL+log的表达和演绎能力。我们通过实例说明了应用场景。关键词:归纳逻辑程序设计,关系数据库,本体,描述逻辑,混合知识表示和推理系统。逻辑程序设计理论与实践(Theory and Practice of Logic Programming,TPLP)

英文摘要:

In this paper we address an issue that has been brought to the attention of the database community with the advent of the Semantic Web, i.e. the issue of how ontologies (and semantics conveyed by them) can help solving typical database problems, through a better understanding of KR aspects related to databases. In particular, we investigate this issue from the ILP perspective by considering two database problems, (i) the definition of views and (ii) the definition of constraints, for a database whose schema is represented also by means of an ontology. Both can be reformulated as ILP problems and can benefit from the expressive and deductive power of the KR framework DL+log. We illustrate the application scenarios by means of examples. Keywords: Inductive Logic Programming, Relational Databases, Ontologies, Description Logics, Hybrid Knowledge Representation and Reasoning Systems. Note: To appear in Theory and Practice of Logic Programming (TPLP).
