古建筑构件及文化的本体模型设计及应用

Ontology Model of Ancient Chinese Architecture Members and Culture Design and Application

为了减轻用户在检索信息过程中的负担,在信息检索中引入本体的概念.本体能够准确描述概念之间的内在关联,为人们提供全面而有效的信息.采用领域本体来表示和组织古建筑领域知识,建立一个集建筑构件、建筑文化和建筑结构为一体的本体模型.利用Java开发一个基于古建筑构件本体的检索系统,抽取本体中的同义词加入查询和检索中,通过实验结果表明不仅为用户提供了准确而全面的查询信息,而且提高了检索的准确率.

In order to reduce the burden of the process of retrieving information, the concept of ontology is introdnced. Ontology describes the connection between the meaning of concept and the concept accurately. It is not only solving the problem of heterogen effectively but also providing the useful information quickly. This paper uses the domain-ontology knowledge to build an ontology model of ancient Chinese architecture and applications in the architecture fields. First, this paper describes the purpose and meaning of the domain-ontology construction. Second, the related ontology knowledge is introduced as the fundamental of the construction. After that, the process of domain-ontology construction will be told in detail, which is composed of the scope of ontology application, the important terms, the overall framework of ontology construction, the classes and its hierarchy system, the definition of properties, etc. At the end, a semantic retrieval system based on this model by Java is developed, and the synonym of ontology is taken to join query and retrieval, in order to effectively improve the recall rate and the precision rate of informationg retrieva.
