Before revision:  The results indicated that the best technique for handling OOV words can be different for each task . But, in general, deep learning models that infer the embedding based on the context and the morphological structure of the OOV word  obtained promising results.
After revision:  The results indicated that the best technique for handling OOV words can be different for each task , Comick, a deep learning method that infers the embedding based on the context and the morphological structure of the OOV word obtained promising results.
