摘要:

 随着语义检索技术在众多领域的不断发展应用,领域本体需求越来越大,手工构造不能满足本体应用的需求。本文从现有本体自动构建方法着手,总结本体自动构建的一般方法,分析以维
基百科结构化数据为基础进行气象本体自动构建的可能性,基于网络链接相互性系数,提取有效子分类;定义距离跳数,进行有效条目的提取,最后提出基于维基百科的气象本体自动构建方法。实验结
果表明,该方法能够达到本体构建的要求,具有速度快、人工干预少的特点,对本体在气象领域的应用具有一定的促进作用。

Abstract:

With the continuous development of semantic retrieval technology in many fields, the requirement of domain ontology is increasing. To construct ontology only by
hand cannot satisfy the requirements of ontology application. This paper, starting from the existing method which builds ontology automatically, summarizes the general method of
building ontology automatically, and analyzes the possibility of building meteorological ontology automatically based on the structured data of Wikipedia, and then extracts the
effective classifications from it according to the network links interaction coefficient. By defining the distance between the hops, we extract the effective entries, finally,
we put forward the meteorological ontology automatic building method based on Wikipedia. The experiment shows that this method which has the higher speed and less manual
intervention can satisfy the requirements of ontology construction. It’s sure that this method has a certain role in the application of meteorological ontology.

Key words: Wikipedia, ontology, relatedness, automated building
