Stanford GloVe's lack of punctuation?

Question

I understand that GloVe trains vectors by noticing what frequently co-occurs, etc, but how come commas and periods are not included? For anything NLP, it seems like it would be an important feature to have a vector representation. I realize that something like (king - man = queen) would make no sense with (word - , = ?), but is there a way to represent punctuation marks and Numbers?

Is there a pre-made data set that includes such things? Would this even work?

I tried training GloVe with my own data set, but I ran into a problem with separating the punctuation (with a blank space) between words, etc.

Answer 1

pre-trained GloVe vectors do have punctuation, what makes you think they don't? At least Wikipedia 2014 + Gigaword 5 (6B tokens) set from http://nlp.stanford.edu/projects/glove/ have embeddings for "," ".", "-" and other included, just download these word vectors, and verify it yourseld, they are in plain text format, so its easy to do.
