Quality and Safety News Topic Tracking Algorithm Based on Improved K-Nearest Neighbor
Yingcheng Xu · 2016
According to the characteristics of deficiency for topic tracking process in initial sample, this paper chooses K-Nearest Neighbor(KNN) algorithm as the method of event and the topic tracking, and takes into account the correlation of product quality and safety WEB news to improve the KNN algorithm.The "hole shoes" event as an example is to verify the algorithm.The result shows that the proposed model is effective and feasible.
