NLU datasets with task-oriented dialogue

Datasets of natural language understanding and dialogue state tracking for task-oriented dialogue, which can be used in research. There are some other survey of datasets in respective of diaogue system, like AtmaHou's Task-Oriented-Dialogue-Dataset-Survey (I am one of the contributors). But we focus on how to build a semantic parser for spoken dialogue system.

If you want to know more about NLU of task-oriented dialogue, please see recommended papers.

There is an implementation of joint training of slot filling and intent detection for SLU, which is evaluated on ATIS and SNIPS datasets.

Table of Contents

Introduction

Items description example
NLU Natural Language Understanding, which should contains text classification, sequence labelling and semantic parsing tasks.
DST Dialogue State Tracking DSTC 2
domain dialogue domain movie, music, flight, restaurant, ...
intent It an abstract meaning which always refers to a sentence or sub-sentence. The intent of "show me a movie named Titanic" is "find_movie"
slot It is attribute or key, which should have a value. "show me a movie named Titanic" has a slot-value pair "movie_name = Titanic"
act type a general speech action inform, deny, confirm, request, hello, bye, ...
dialogue act act_type(slot=value,...), https://github.com/matthen/dstc/blob/master/handbook.pdf inform(movie_name = Titanic), request(price), ...
  • Intent Detection or intent classification: sentence classification task
  • Slot Tagging: sequence labelling task
  • Slot Filling: It equals to slot tagging if all values of slots can be aligned into input sentence. Otherwise, the value of slot should be predicted in a classification or generation way.
