Abstract

Collaborative filtering recommendation algorithm based on KNN neighbor selection does not consider the blind follower of neighbors when selecting neighbors, which causes some neighbor users to play a minor role in predicting the target user's scoring of unknown items. In response to this problem, a contribution factor is proposed. Jointly evaluate the item set from this perspective, consider the neighboring user's recommendation capability, calculate the neighboring user's recommendation contribution, combine the traditional user similarity to jointly select the neighbors, and recalculate the neighbor user's weight of the unknown project to improve the recommendation performance. Experimental results show that this improved algorithm improves recommendation accuracy.
