Leaderboard: None
Who transforms the dataset: Qi Zhu(zhuq96 at gmail dot com)

To use this dataset, you need to install ConvLab-3 platform first. Then you can load the dataset via:

from convlab.util import load_dataset, load_ontology, load_database

dataset = load_dataset('tm1')
ontology = load_ontology('tm1')
database = load_database('tm1')

For more usage please refer to here.

Dataset Summary

The original dataset consists of 13,215 task-based dialogs, including 5,507 spoken and 7,708 written dialogs created with two distinct procedures. Each conversation falls into one of six domains: ordering pizza, creating auto repair appointments, setting up ride service, ordering movie tickets, ordering coffee drinks and making restaurant reservations.

How to get the transformed data from original data:
- Download master.zip.
- Run python preprocess.py in the current directory.
Main changes of the transformation:
- Remove dialogs that are empty or only contain one speaker.
- Split woz-dialogs into train/validation/test randomly (8:1:1). The split of self-dialogs is followed the original dataset.
- Merge continuous turns by the same speaker (ignore repeated turns).
- Annotate dialogue acts according to the original segment annotations. Add intent annotation (inform/accept/reject). The type of dialogue act is set to non-categorical if the original segment annotation includes a specified slot. Otherwise, the type is set to binary (and the slot and value are empty) since it means general reference to a transaction, e.g. "OK your pizza has been ordered". If there are multiple spans overlapping, we only keep the shortest one, since we found that this simple strategy can reduce the noise in annotation.
- Add domain, intent, and slot descriptions.
- Add state by accumulate non-categorical dialogue acts in the order that they appear, except those whose intents are reject.
- Keep the first annotation since each conversation was annotated by two workers.
Annotations:
- dialogue acts, state.
