| 摘 要： | 文章提出一种改进的关联规则方法，用于抽取文本中的非分类关系。首先利用基于上下文的术语相似度获取方法得到术语间的相似度权重，再通过加入谓语动词的关联规则算法计算，结合搜索引擎技术得到候选关系对集合，并通过置信度和支持度的对比分析，抽取最终的非分类关系结果，最后对测试数据进行实验，并对结果进行分析。 |
| 关 键 词： | 关联规则 非分类关系 本体 |

| Abstract: | An improved method of association rules used to extract the non-taxonomic relationships from the text is proposed.Firstly,the weight of the similarity between the terms is extracted by computing the similarly between the terms based on the context.Secondly,the collection of candidate relationship pairs is obtained by computing the association rules with verbs and by the use of search engine technologies,and the final non-taxonomic relationship results are extracted by comparative analysis of confidence and ... |
