- What’s the problem here; is word2vec not up to the task?[31]
- A couple of questions you might have right about now: how does word2vec work?[31]
- Word2vec performs an unsupervised learning of word representations, which is good; these models need to be fed with a sufficiently large text, properly encoded.[31]
- Word2vec is a group of related models that are used to produce so-called word embeddings.[32]
- After training, word2vec models can be used to map each word to a vector of typically several hundred elements, which represent that word's relation to other words.[32]
- Word2vec relies on either skip-grams or continuous bag of words (CBOW) to create neural word embeddings.[32]
- getVecFromWord" it should be able to handle any word, including those not found in the word2vec model.[32]
