To reveal the evolution of topics, we propose a temporal clustering method based on bursts of phrases in articles.

Then in clustering, component pattern vectors of phrases which show high cosine similarity will be clustered and key phrases that can explain burst component patterns in a cluster are selected to indicate the topic of the cluster.
