----------------------------------------
Summary: Implement findAnalogies method for Word2VecModel
Key: SPARK-19892
URL: https://issues.apache.org/jira/browse/SPARK-19892
Project: Spark
Issue Type: New Feature
Components: MLlib
Affects Versions: 2.1.0
Reporter: Benjamin Radford
Priority: Minor
Word2VecModel is missing a method that allows for performing analogy-like
queries on word vectors (e.g. King + Woman - Man = Queen). This is a
functionality common to other word2vec implementations (see gensim) and is a
major component of word2vec's appeal as cited in seminal works on the model
(https://code.google.com/archive/p/word2vec/).
An implementation of this method, findAnalogies, should accept three arguments:
* positive - Array[String] of similar words
* negative - Array[String] of dissimilar words
* num - Int number of synonyms or nearest neighbors to calculated vector
