Word2Vec and GloVe are two core word embedding techniques used to learn word vectors using a text corpus. Please suggest me the suitable one to use it in recommendation environment.
Word2Vec and Doc2Vec are more reliable word embedding techniques and and learn words from a large corpus more quickly against Glove .
Dear Zafar Word2vec is a "predictive" model but GloVe is a "count-based" model .
Word2Vec main purpose to train a model on the context on each word, so similar words will have similar numerical representations, while
GLOVE learns by constructing a co-occurrence matrix (words X context) that basically count how frequently a word appears in a context.

Hello;
Let me describe the process of Word2Vec then it easily will understandable which one is better and why!
Somehow Word2Vec is like a typical Neural Network models which the document are converted to sentences and sentences are tokenized to aspect-levels as well.
But the last stage of conversion has a difference between ordinary NN and a model of Word2vec.
Here the pair of words will be made up by the window size.
The optimization method minimize the loss function (target word/context word)
If we do the process in enough epochs then the embedding layer illustrates the coordinates.
As I described the Word2vec is a predictive model on the other hand Glove formed based on word count so keeping all of the occurrences consuming extravagant memory. Although for escaping of exceeding memory consumption it is a force to optimize the data structure (Matrix), eventually a massive amount of data will be lost.
For further study, I added a manuscript, hope this will help you

On real life tasks like NER and sentence classification, Glove embeddings tend to work better than word2vec.
