I got clustering up and running with that in about ten minutes with k-means from scikit learn and wow, all the articles about Ukraine got clustered, all the sports, all the deep learning, all the reinforcement learning. It is way faster than my LDA clustering engine and I think gets better results. See sbert.net for a library that puts it on your fingertips.

(With DBSCAN it shows great promise for clustering news articles about the same topic..)
