摘要 提出一种基于领域本体的新术语扩充方法。结合传统基于统计和基于规则的方法,计算词语在文档中的影响程度,使用领域本体体现领域知识,通过在文档中识别出本体中概念计算文档及词语的领域相关度,获得术语候选项的推荐排序,对术语候选项结果进行优化。实验结果证明了该方法的有效性和可行性。 A method for new term expansion based on domain ontology is proposed.This method combines linguistic rules and statistical methods to get the infection degree from a word to a document.It optimizes the term candidate result,uses domain ontology to recognize concept in document and to calculate correlation degree between word,document and specific domain.The validity of the method is proved with a practical case.
