### Dataset Summary

The 20 Newsgroups data set is a collection of approximately 20,000 newsgroup documents, partitioned (nearly) evenly across
20 different newsgroups. To the best of my knowledge, it was originally collected by Ken Lang, probably for his Newsweeder:
Learning to filter netnews paper, though he does not explicitly mention this collection. The 20 newsgroups collection has become
a popular data set for experiments in text applications of machine learning techniques, such as text classification and text clustering.

does not include cross-posts and includes only the "From" and "Subject" headers.
