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('camrest')
ontology = load_ontology('camrest')
database = load_database('camrest')

Dataset Summary

Cambridge restaurant dialogue domain dataset collected for developing neural network based dialogue systems. The two papers published based on this dataset are: 1. A Network-based End-to-End Trainable Task-oriented Dialogue System 2. Conditional Generation and Snapshot Learning in Neural Dialogue Systems. The dataset was collected based on the Wizard of Oz experiment on Amazon MTurk. Each dialogue contains a goal label and several exchanges between a customer and the system. Each user turn was labelled by a set of slot-value pairs representing a coarse representation of dialogue state (slu field). There are in total 676 dialogue, in which most of the dialogues are finished but some of dialogues were not.

• How to get the transformed data from original data:
  • Run python preprocess.py in the current directory. Need ../../camrest/ as the original data.
• Main changes of the transformation:
  • Add dialogue act annotation according to the state change. This step was done by ConvLab-2 and we use the processed dialog acts here.
  • Rename pricerange to price range
  • Add character level span annotation for non-categorical slots.
• Annotations:
  • user goal, dialogue acts, state.
