KddRES

This is the first Cantonese knowledge-driven Dialogue Dataset for REStaurant (KddRES) in Hong Kong, which grounds the information in multi-turn conversations to one specific restaurant. It contains 0.8k conversations which derive from 10 restaurants with various styles in different regions. In addition to that, we designed fine-grained slots and intents to better capture semantic information.

We have also prepared a version of Simplified Chinese.

• data_zh_hans: Simplified Chinese version
• data_zh_hant: Cantonese version

Data

We introduce the concept of secondary slots to better record fine-grained slots’ information. A secondary slot refers to a slot that containing more detailed information. For example, when a user wants to know about a restaurant’s dishes, task-oriented dialogue system can not only tell the name of the dishes, but also the price of the dishes. User can also specifically ask about the price of a certain dish. Dishes and Dishes-price are the secondary slots in this scenario.

All secondary slots and their primary slots in KddRES(translated into English):

Data statistics:

POSS is the proportion of dialogues that contain the secondary slots

Experiment

We have implemented NLU(Natural Language Understanding) on KddRES with four models: BiLSTM, BiLSTM+CRF,BERTNLU and HierBERT.
