Nowadays clustering has become a popular text mining algorithm, but the huge data can put forward higher requirements for the accuracy and performance of text mining.In view color block iphone case of the performance bottleneck of traditional text clustering algorithm, this paper proposes a text clustering algorithm with random lightemupsequences.com features.This is a kind of clustering algorithm based on text density, at the same time using the neighboring heuristic rules, the concept of random cluster is introduced, which effectively reduces the complexity of the distance calculation.
