基于叙词表的油田领域本体构建方法

摘要

在对比研究现有本体构建方法的基础上，提出了基于叙词表的油田领域本体构建方法，该方法可以减少构建本体的工作量，重点解决了叙词表向本体转化过程中的一些问题，如概念选择的不确定性，词间一些不确定关系的表示及关系细化等，提出了叙词表中“用、代、分、属、参”关系进一步细化的原则，并给出了如何利用OWL描述语言表示叙词及叙词之间的多种关系，从而实现了叙词表的OWL描述。%Compared with the existing ontology construction methods, the approach of building oilfield domain ontology based on Thesaurus is proposed, which can alleviate the amount of work involved in building ontology, and solve a series of problems in the process of transformation from the thesauri to the ontology, such as the selecting of some uncertainty concept, the representation of some uncertainty relationships among words in thesaurus and the refinement of those relationships. This paper proposes a series of principles which describe the refinement of “USE、UF、NT、BT、TT、RT” five relationships in thesaurus, and presents how to use OWL language to describe the thesaurus and several relationships among words, so as to realize the OWL description of the Thesaurus.
