Building a text sentiment classifier with GloVe word embedding

Stanford University's Pennington, et al. developed an extension of the word2vec method that is called Global Vectors for Word Representation (GloVe) for efficiently learning word vectors. 

GloVe combines the global statistics of matrix factorization techniques, such as LSA, with the local context-based learning in word2vec. Also, unlike word2vec, rather than using a window to define local context, GloVe constructs an explicit word context or word co-occurrence matrix using statistics across the whole text corpus. As an effect, the learning model yields generally better word embeddings.

The text2vec library in R has a GloVe implementation that we could use to train to obtain word ...
