| 摘 要： | 目前个性化推荐领域的相关研究,很少考虑用户在资源属性上的兴趣差异,而资源属性往往是决定用户偏好的重要因素之一。针对这一问题,构建了基于资源多属性的用户评价模型和兴趣模型,并提出了一种改进的Pearson-Compatibility多属性群决策算法,在k-临近相似用户的推荐问题中引入该算法,结合协同过滤推荐的特点,对相似用户偏好差异性、残缺值、算法可能出现的提前收敛等问题进行了充分考虑,进而实现多属性的协同过滤。最后通过实验对算法的有效性进行验证,实验结果表明:算法在目标用户属性偏好的预测上,具有较高的准确度,对偏差值、残缺值具有较强的抗干扰能力,具有较强的实用价值。

| Abstract: | At present,in the field of personalized recommendation,insufficient attention is given to the differences of users' interest on the attributes of resources;however,the attributes of resources are usually an important factor to determine users' preferences.To this end,we constructed a user evaluation model and user interest model based on resource multi-attribute and proposed an improved Pearson-Compatibility group decision algorithm.We introduced the algorithm to solve the recommendation problem of k-neighb... |
