Word2Vec

Arguably the most important application of machine learning in text analysis, the Word2Vec algorithm is both a fascinating and very useful tool. As the name suggests, it creates a vector representation of words based on the corpus we are using. But the magic of Word2Vec is in how it manages to capture the semantic representation of words in a vector. The papers, Efficient Estimation of Word Representations in Vector Space [1] [Mikolov and others, 2013], Distributed Representations of Words and Phrases and their Compositionality [2] [Mikolov and others, 2013], and Linguistic Regularities in Continuous Space Word Representations [3] [Mikolov and others, 2013] lay the foundations for Word2Vec and describe their uses.

We've mentioned that these word vectors help represent the semantics of words what exactly does this mean? Well for starters, it means we could...
