基于WordNet与Wikipedia的平面几何本体的构建

摘要

针对目前本体构建中存在的如手工构建难以确保高效性和可扩展性，且自动构建难度大，可操作性不强等研究现状，提出了一种基于WordNet和Wikipedia的学科领域本体半自动构建方法。首先构建一个领域顶层本体，在此基础上，重用WordNet的结构，从深度上对其进行术语和术语层次的扩展；同时根据Wikipedia中的页面信息，从广度上对其进行术语间关系的扩展和术语的补充；并将该本体构建方法应用于平面几何领域。实验表明该方法能大大提高本体构建的效率，并在一定程度上保证了本体的质量。%Ontology, as a member of the Semantic Web’s hierarchical structure, is located in the central position. Regarding the current research situation of ontology construction, the manual construction is difficult to ensure its efficiency and scalability;and the automatic construction is hard to guarantee its interoperability. This paper presents a semi-automatic domain ontology construction method based on WordNet and Wikipedia. First, we construct the top-level ontology and then reuse WordNet structure to expand the terminology and terminology-level at the depth of the ontology. Furthermore, we expand the relationship and supplement the terminology at the width of the ontology by referring to page information of Wikipedia. Finally, this method of ontology construction is applied in elementary geometry domain. The experiments show that this method can greatly improve the efficiency of ontology construction and ensure the quality of the ontology to some degree.
