Task: Question Answering
Input (English): In this way, an attention vector sequence is segmented into several subsequences and each subsequence represents the attention of one word. Then, motivated by the psycholinguistic finding that readers are likely to pay approximate attention to each character in one Chinese word, we devise an appropriate aggregation module to fuse the inner-word character attention. 
 Question: How does the fusion method work?
Output (English): ttention vector sequence is segmented into several subsequences and each subsequence represents the attention of one word we devise an appropriate aggregation module to fuse the inner-word character attention
