摘要：通过对可拓学的基元和复合元与知网的研究，利用Hownet中的词语相似度的计算方法改进词语相关度的计算方法，建立基元相关度计算方法，进而建立目标相关度和条件相关度的计算机方法，形成问题相关度的计算。改进了相关度算法，传统方法只通过上下位关系计算词语相关度，将知网描述的其他15个关系也考虑进来，并提出了负相关的概念，将相关度的取值范围定在[-1，1]，对应了关联函数的值域。通过对基元中特征与特征的对应关系，计算出基元的相关度，进而计算问题的相关度。通过对数据库里的上千个矛盾问题进行测试，证实了这种方法可有效增加策略生成途径，使矛盾问题解决的概率大大提高。

Abstract：Based on the basic-element and composite elements of extenics and HowNet research, the words similarity computing method in HowNet is used to improve the calculation method for the relationship of words. The basic-element correlation calculation method is built to establish a method for basic-element target correlation and basic-element conditions correlation. This is used to derive the method to calculate correlation of problem. There is improvement with the correlation algorithm, but the traditional method calculates the correlation of words only by hyponymy. In this paper, an additional fifteen relationships described in HowNet is taken into account. The concept of negative correlation is put forward and the range of correlation is in set [-1, 1], which corresponds to the range of the correlation function. Through the corresponding relationship between the features in the basic element, the correlation between basic elements is calculated and the correlation of problems can be calculated. Based on the test of thousands of contradictory problems in the database, the results showed that this method can effectively increase the amount of strategy generating approaches and the probability of contradictory problems to be solved is greatly promoted.
