Abstract: Recommendation engine algorithm is collaborative filtering and personalized recommendation technology which, by viewing the habits of a large user groups, picks out the most extensive users who will choose to continue watching after watching a video and recommends to the new users. This study designs the cloud mining architecture and technology implementation in the network video applications, gives the cloud mining formalized algorithm and analyzes the network video programs by using collaborative filtering algorithm based on content. This algorithm should be the best algorithm for cloud mining in the recommended application of network video.
