一种数学表达式检索结果相关排序算法
A Relevance Ranking Algorithm of Mathematical Expression Retrieval Results
摘要
Abstract
Aiming at the characteristics of mathematical expressions,such as the diversity of mathematical symbols,the complexity of structures and the richness of semantics,a mathematical expression retrieval results ranking algorithm is proposed.It utilizes the advantages of the hesitant fuzzy sets in dealing with the problems with multiple features and membership values to calculate the similarity between mathematical expressions,based on which the mathematical expressions are ranked.It measures the similarity of mathematical expressions through constructing the hesitant fuzzy membership with the multidimensional characteristics of the symbols,structures,grammar and semantics of mathematical expressions.Experimental results show that the algorithm can not only realize ordered output of search result data,but also improve the performance of mathematical expression retrieval system.关键词
