To understand the basics of NLP, I would suggest to have a look at word embeddings, one hot encoding and bag of words, n-grams, lemmatisation, stemming, and if you're not familiar with deep learning, recurrent neural networks and convolutional neural networks.
These concepts are well known and you can easily find papers/articles/books about it.
I would also suggest you "Speech and Language Processing" which is quite a nice book to introduce NLP.
Thank you for that link eclipto. I was looking for something similar but couldn't find any satisfying ressource.
Yes. I was just planning to learn more about that on my spare time as it seems at least as interesting as word2vec :)
Sounds interesting. It is some kind of doc2vec technique isn't it ?
great idea, count me in !
