MuTual: A Dataset for Multi-Turn Dialogue Reasoning (ACL2020)

MuTual is a retrieval-based dataset for multi-turn dialogue reasoning, which is modified from Chinese high school English listening comprehension test data. Please see our paper for more details.

We also provide several baselines to facilitate the further research. (Coming soon)


The process of modifying the listening comprehension test data.

Examples from the MuTual dataset. All choices are relevant to the context, but only one of them is logic correct. Some negative choices might be reasonable in extreme cases, but the positive one is the most appropriate. Clue words are purple and underline.

Data template

are the training, development and test sets, respectively. After loading each file, you will get a dictionary. The format of them is as follows:
{"answers": "B", 
"options": ["m : so you come to manchester just for watching a concert , do n't you ?", "m : i really want to say that your performance in manchester must will be great !", "m : you come to manchester specially for this friend , so your friendship must be very deep .", "m : is this your first performance in manchester ? i remember you never sang at a high school concert ."],

is a list of four candidates' response.

indicate female and male, respectively.

is the correct answer. Noted that we do not realease the correct answer on test set.

Please send your predictions (decode output) in the sample format(

id + "\t" + rank1prediction + "\t" + rank2prediction + "\t" + rank3prediction + "\t" + rank4prediction
one instance per line), methods and dev performance to [email protected] . We will evaluate your results according to the Eval Script.
