Effective Character-Augmented Word Embedding for Machine Reading Comprehension
Machine reading comprehension is a task to model relationship between passage and query.In terms of deep learning framework,most of state-of-the-art models simply concatenate word and character level representations,which has been shown suboptimal for the concerned task.In this paper,we empirically explore different integration strategies of word and character embeddings and propose a characteraugmented reader which attends character-level representation to augment word embedding with a short list to improve word representations,especially for rare words.Experimental results show that the proposed approach helps the baseline model significantly outperform state-of-theart baselines on various public benchmarks.
