GloVe与word2vec,两个模型都可以根据词汇的“共现co-occurrence”信息,将词汇编码成一个向量(所谓共现,即语料中词汇一块出现的频率)。两者最直观的区别在于,word2vec是“predictive”的模型,

Because that PyPI package appears to be a thin wrapper around the word2vec.c code originally released by Google, you could probably refer to that code to learn more details about formats/usage. But, you could also use the Word2Vec implementation in the Gensim library – a far more common choice when using Python, with much more documentation & flexibility.

The current key technique to do this is called “Word2Vec” and this is what will be covered in this tutorial. After discussing the relevant background material, we will be implementing Word2Vec embedding using TensorFlow (which makes our lives a lot easier.

Gensim has also provided some better materials about word2vec in python, you can reference them by following articles: models.word2vec – Deep learning with word2vec Deep learning with word2vec and gensim Word2vec Tutorial Making sense of word2vec GloVe in
