| 摘 要： | 提出了一种基于术语间本体关联度的文档相关度计算方法，该方法利用树状本体结构计算术语间基于本体的关联关系，通过术语组间的本体关联度得到两组词语的本体关联关系，最后结合文档标引词的权重计算两个文档的相关度。新方法从本体的角度将语义信息融入传统向量空间模型，提高了文档相关度计算的准确性。实验选取计算机领域本体作为实验数据，对新方法和传统方法进行综合对比评测，实验结果验证了新方法的有效性和合理性。

| Abstract: | A calculation method of document relevancy based on ontology term relafions is putted forward, which uses treelike ontological structure to calculate the rehted relafiomhip between terms, obtains the ontology rehfionships between two groups of words through the ontology correlation degree of terms, finally merges the weight of indexed words to compute the relevancy of two documents. This method merges semantic information to traditional vector space model from ontology, improving the accuracy of document wlevancy. The paper adopt computer domain ontology as experimental data, experimental results testify the rationality and effectiveness of the new method. |
