To enable accurate multi-domain DST, the model needs to encode dependencies between past utterances and slot semantics and understand the dialog context

AAAI 20202020Machine Reading Comprehension (MRC) for question answering (QA), which aims to answer a question given the relevant context passages, is an important way to test the ability of intelligence systems to understand human language. Multiple-Choice QA (MCQA) is one of the most difficult tasks in MRC because it often requires more advanced reading comprehension skills such as logical reasoning, summarization,
