AI总结:

针对本体合并中的异构性问题,提出基于属性的上下文相似性指标和机器学习 etype 识别算法,实验证明其优于现有方法。

摘要:

本体开发的主流方法是合并编码不同信息的本体,其中主要困难之一是异构性既推动了本体合并,又限制了高质量的合并性能。因此,实体类型(etype)识别任务被提出以应对这种异构性,旨在利用本体中编码的信息推断实体和 etype 的类别。本文提出一种基于属性的方法,可依据用于定义 etype 的属性来识别 etype。从认识论角度看,实际上正是属性刻画了实体和 etype,且这种定义独立于用于定义它们的特定标签和层次模式。主要贡献包括一组用于度量 etype 与实体之间上下文相似性的基于属性的指标,以及一种利用所提出相似性指标、基于机器学习的 etype 识别算法。与最先进方法相比,实验结果证明了这些相似性指标的有效性以及所提 etype 识别算法的优越性。

英文摘要:

The mainstream approach to the development of ontologies is merging ontologies encoding different information, where one of the major difficulties is that the heterogeneity motivates the ontology merging but also limits high-quality merging performance. Thus, the entity type (etype) recognition task is proposed to deal with such heterogeneity, aiming to infer the class of entities and etypes by exploiting the information encoded in ontologies. In this paper, we introduce a property-based approach that allows recognizing etypes on the basis of the properties used to define them. From an epistemological point of view, it is in fact properties that characterize entities and etypes, and this definition is independent of the specific labels and hierarchical schemas used to define them. The main contribution consists of a set of property-based metrics for measuring the contextual similarity between etypes and entities, and a machine learning-based etype recognition algorithm exploiting the proposed similarity metrics. Compared with the state-of-the-art, the experimental results show the validity of the similarity metrics and the superiority of the proposed etype recognition algorithm.
