摘　　要：分析目前比较流行的两种推荐算法各自存在的优缺点,针对两种单一推荐算法各自的优缺点,提出一种基于定性映射的混合推荐算法模型,以拓扑邻域为定性基准进行邻近查找操作,通过转化程度函数对结果进行优化,提高推荐系统的推荐精度,并通过实验验证该混合算法的可行性和精确性。Analyzes the advantages and disadvantages of the two kinds of recommendation algorithms which are popular currently. In view of the ad- vantages and disadvantages of the two kinds of recommendation algorithms of their respective, presents a hybrid recommendation algo- rithm based on qualitative mapping method. Takes the topological neighborhood as a qualitative matrix, the degree of conversion function by optimizing the results to improve the recommendation accuracy of the recommendation system, and through experiments validate the feasibility and accuracy of the hybrid algorithm.
