本体映射方法研究

本体集成是为了解决不同本体之间的共享和交流，其中本体映射是本体集成的一个关键环节。在以往的系统中，本体映射通常是由手工实现的。目前的研究都是朝着实现本体映射的自动或半自动化方向努力。文章对目前本体映射的方法进行了分类，针对本体定义模型，提出了基于语法、基于实例、基于定义、基于层次结构的分类。针对具体映射实现技术。提出了基于规则、基于统计学、基于机器学习的分类。并对每种方法进行了详细描述。这项研究工作可以作为人们提出新的映射方法或者组合的映射方法的一个参考。

Survey of Ontology Mapping Approaches

Ontology integration is a solution to share and communicate with each other among ontologies.And ontology mapping is the key tache in ontology integration.In existing applications it is achieved manually.So that a semiautomatic or automatic approach to map between entities from different ontologies is the research direction now and in the future.The existing approaches are classified in this paper.They include approaches based on syntax,instances,definition and hiberrarchy according to ontology definition model.And they can be classified into rule-based,statistics-based,machine learning approaches according to mapping technics.Meanwhile each approaches are described detailedly.And it can be a reference to others to put forward a new approach.or give a hybria one.
