Li Ping Zhang commented on SPARK-14864:
---------------------------------------

Agree. I think it would extend spark user a lot if doc2vec is implemented in spark, and we do have several real use scenarios about running doc2vec with large scale data.

> It would be useful to implement Doc2Vec, as described in the paper [Distributed Representations of Sentences and Documents|https://cs.stanford.edu/~quocle/paragraph_vector.pdf]. Gensim has an implementation [Deep learning with paragraph2vec|https://radimrehurek.com/gensim/models/doc2vec.html]. 
> Le & Mikolov show that when aggregating Word2Vec vector representations for a paragraph/document, it does not perform well for prediction tasks. Instead, they propose the Paragraph Vector implementation, which provides state-of-the-art results on several text classification and sentiment analysis tasks.
