> [MLLIB] Improve API in Word2Vec model
> -------------------------------------
>
> Key: SPARK-4101
> URL: https://issues.apache.org/jira/browse/SPARK-4101
> Project: Spark
> Issue Type: Improvement
> Components: MLlib
> Affects Versions: 1.1.0
> Reporter: Peter Rudenko
> Priority: Minor
>
> 1) Would be nice to be able to retrieve underlying model map, to be able to
> work with it after (make an RDD, persist/load, online train, etc.). (Done by
> [SPARK-4582|https://issues.apache.org/jira/browse/SPARK-4582] )
> 2) Be able to extend Word2VecModel to add custom functionality (like add
> analogyWords(w1: String, w2: String, target: String, num: Int) method, which
> returns n words that relates to target as w1 to w2).
> 3) Make cosineSimilarity method public to be able to reuse it.
