一种优化的基于协同过滤的农业信息推荐系统研究

随着信息爆炸而引发的信息过载和资源迷向的问题日趋严重,特别是对于农民来说,对计算机技术的掌握不多。为了向农民及时、方便、高效地提供其感兴趣的农业信息及知识,许多学者都对推荐系统技术进行了研究。为此,首先介绍了目前推荐系统的关键技术,并针对目前推荐系统中存在的用户评价矩阵稀疏问题提出了通过项目聚类来构造出一个无缺失的用户评价矩阵。考虑到农民行为差异性,在进行评价预测之前先对评分进行标准化处理。

Research on Optimized Agricultural Information Recommendations System Based on Collaborative Filtering

With the problems of information overload and resource disorientation which is caused by information explosion become more serious,especially for lots of farmers,they know little computer technologies.In order to provide information and knowledge timely,conveniently and efficiently to farmers,lots of researchers do studies about recommendations system.In this paper,key technologies in recommender system are introduced.We provide a solution that construct a non-missing data user evaluation matrix through the...
