Abstract: To enhance the efficiency of data sharing and the satisfaction of big data alliance members in manufacturing industry,a resource pushing algorithm based on mutual information feature weight and similarity was proposed.To improve the quality of resource push,the scores of big data alliance members and the nearest neighbors were improved by using mutual information feature weight and feature similarity.The results showed that the algorithm could solve the problem of data push and data sparsity of alliance new members to a certain extent,and improve the satisfaction of big data alliance members effectively.

摘要： 为了提高制造业大数据联盟资源共享效果及联盟成员的满意度,提出一种基于互信息特征权重和相似度的制造业大数据联盟资源推送算法。利用互信息特征权重和特征相似度分别对制造业大数据联盟成员评分和最近邻居产生的评分加以改进,从而提高资源推送质量。实验结果表明,该算法在一定程度上解决了制造业大数据联盟新成员资源推送和数据稀疏问题,有效提高了制造业大数据联盟成员满意度。
