Calculation of correlation problem based on basic element and HowNet
摘要
Abstract
Based on the basic⁃element and composite elements of extenics and HowNet research, the words similari⁃ty 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 im⁃provement with the correlation algorithm, but the traditional method calculates the correlation of words only by hy⁃ponymy. 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 cor⁃relation 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 promo⁃ted.关键词
