The first project in this book is about the 20 newsgroups dataset found in scikit-learn. The data contains approximately 20,000 across 20 online newsgroups. A newsgroup is a place on the Internet where you can ask and answer questions about a certain topic. The data is already split into training and test sets. The cutoff point is at a certain date. The original data comes from http://qwone.com/~jason/20Newsgroups/. 20 different newsgroups are listed as follows:
- comp.graphics
- comp.os.ms-windows.misc
- comp.sys.ibm.pc.hardware
- comp.sys.mac.hardware
- comp.windows.x
- rec.autos
- rec.motorcycles
- rec.sport.baseball
- rec.sport.hockey
- sci.crypt
- sci.electronics
- sci.med
- sci.space
- misc.forsale
- talk.politics.misc
- talk.politics.guns
- talk.politics.mideast
- talk.religion.misc
- alt.atheism
- soc.religion.christian
All the documents in the dataset are in English. And from the newsgroup names, you can deduce the topics...
