Simple Algorithms For Sentiment Analysis On Sentiment Rich, Data Poor Domains.

no code implementations COLING 2018 Prathusha K Sarma, William Sethares

SWESA leverages document label information to learn vector representations of words from a modest corpus of text documents by solving an optimization problem that minimizes a cost function with respect to both word embeddings and the weight vector used for classification.
