Task: Question Answering
Input (English): First, in order to deal with the unseen relations, we propose to break the relation names into word sequences for question-relation matching. Second, noticing that original relation names can sometimes help to match longer question contexts, we propose to build both relation-level and word-level relation representations. Third, we use deep bidirectional LSTMs (BiLSTMs) to learn different levels of question representations in order to match the different levels of relation information. Finally, we propose a residual learning method for sequence matching, which makes the model training easier and results in more abstract (deeper) question representations, thus improves hierarchical matching. 
 Question: What they use in their propsoed framework?
Output (English): break the relation names into word sequences  relation-level and word-level relation representations bidirectional LSTMs (BiLSTMs)  residual learning method
