Thanks Kevin. This slipped my mind.
Glove (or rather GloVe, Glove is just easier to type) stands for Global Word Vectors. The package implements the algorithm in described http://nlp.stanford.edu/projects/glove/. The idea is to represent words as a vector of floats that capture word similarities. For example, "king - man + woman = queen" (operating on word vectors). The other popular implementation is word2vec, https://code.google.com/p/word2vec/.
