摘　　要：近年来,为了解决推荐系统的用户冷启动问题,信任推荐技术得到了长足发展。然而,传统的信任推荐技术在处理信任关系上比较粗糙。基于信任环的推荐思想严格控制了信任度对推荐结果的影响。实验结果表明,该方法能有效解决用户冷启动问题,并提高推荐的准确率。In recent years, to solve the problem of user cold-start on recommendation system, the technology of trustbased recommendation has got rapid development. However, in transacting the trust relationship, traditional trust-based recommendation technologies seem to be comparatively rough. The idea of trust-circle based strictly controls the effects of trust degree on the results of recommendation. As experimental results show, this method can not only efficiently settle the user cold-start problem, but also improve the precision of recommendation.
