Dataset Card for WOZ 2.0

• Repository: https://github.com/nmrksic/neural-belief-tracker/tree/master/data/woz
• Paper: https://aclanthology.org/P17-1163.pdf
• 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('woz')
ontology = load_ontology('woz')
database = load_database('woz')

For more usage please refer to here.

Dataset Summary

Describe the dataset.

• How to get the transformed data from original data:

  • download woz_[train|validate|test]_en.json from https://github.com/nmrksic/neural-belief-tracker/tree/master/data/woz and save to woz dir in the current directory.
  • Run python preprocess.py in the current directory.

• Main changes of the transformation:

  • domain is set to restaurant.
  • normalize the value of categorical slots in state and dialogue acts.
  • belief_states in WOZ dataset contains request intents, which are ignored in processing.
  • use simple string match to find value spans of non-categorical slots.

• Annotations:

  • User dialogue acts, state

• cat slot match: how many values of categorical slots are in the possible values of ontology in percentage.
• non-cat slot span: how many values of non-categorical slots have span annotation in percentage.
