本体对齐技术概述及其在中医领域的应用探讨

本体对齐技术是实现不同来源本体概念和关系整合的知识工程方法，鉴于相同范围的本体（如疾病本体）往往由多个不同领域或机构的研究人员各自独立研发，其术语表述和概念关系都存在较大差异。因此，如何通过对齐处理以实现多源本体的整合成为重要的方法学问题。本文就本体对齐的概念、技术、方法及其相应的工具进行了详细阐述。重点阐述了基于语言学特征的和基于结构特征的本体对齐技术。结合国际上两个实际疾病本体：Disease Ontology和Orphanet，采用本体对齐技术进行了实验及分析，并详述对齐技术的应用问题。针对中医领域本体库研发中也存在的多源性问题，进一步探讨本体对齐应用的必要性和应用前景。

The Overview of Ontology Alignment techniques and Their Applications to Traditinoal Chinese Medicine(TCM)

Ontology alignment technology is a knowledge engineering method to realize the concept and relationship integration of different ontologies.In view of the same scope of ontology, such as disease ontology,developed by researchers from a number of different areas or institutions of independent research and development,there is a big difference between the term expression and the concept of the relationship.Thus,how to achieve the integration of multi-source ontology through alignment processing has been recognized as a significant methodological problem. In this paper, the concept,technology,method and corresponding tool of ontology alignment were expounded at full length.The technique of ontology alignment based on linguistic features and structural features was emphasized.Combined with the two international disease ontology:Disease Ontology and Orphanet,the experiment and analysis of the technique of ontology alignment were carried out and detailed the application of alignment technology.Furthermore,for the existing multi-source problems on TCM ontology database,the necessity and application of ontology al ignment were discussed.
