在分析和研究国内外基于向量空间模型的文本拟合度计算方法的基础上，提出了一种递归下降的政策文本拟合度计算方法。该方法基于政策文本预处理和递归下降等技术给出了政策子句拟合度计算方法和政策语篇拟合度计算方法。该方法不直接建立一般经典算法都要涉及的词频向量，而是将相同词汇进行合并。然后利用递归下降的方法，从政策子句、段落和语篇三个不同的层次分析政策语篇的一致性问题，降低拟合度计算的空间复杂度。实验结果表明，该方法与现有的一些拟合度计算方法相比，有效地提高了一致性验证的效率和准确率。

This paper proposed a new policy text similarity calculation method after the analysis and research of the domestic and foreign traditional text similarity calculation based on vector space model.The method which was based on the policy text pretreatment and recursive descent technology presented a computation method of fitting degree among policy clauses and simi-larity among policy text.The general classic algorithms were involved in the problem of word frequency,this method did estab-lish word frequency vector directly,but it merged the same words.Then by using the recursive descent method,the method analyzed the consistency problem in policy chapters from three different levels of policy clauses,policy paragraphs and policy chapters,reducing the space complexity of the fitting calculation.Experimental results show that compared with the existed typical similarity calculation method,this method can increase the efficiency and precision of consistency verification.
