Simplifying Dataflow Dialogue Design
In \citep{andreas2020task-oriented}, a dataflow (DF) based dialogue system was introduced, showing clear advantages compared to many commonly used current systems. This was accompanied by the release of SMCalFlow, a practically relevant, manually annotated dataset, more detailed and much larger than any comparable dialogue dataset.Despite these remarkable contributions, the community has not shown further interest in this direction.What are the reasons for this lack of interest? And how can the community be encouraged to engage in research in this direction?One explanation may be the perception that this approach is too complex - both the the annotation and the system. This paper argues that this perception is wrong: 1) Suggestions for a simplified format for the annotation of the dataset are presented, 2) A basic implementation of the DF execution engine is released, which can serve as a sandbox allowing researchers to easily implement, and experiment with, new DF dialogue designs.The hope is that these contributions will help engage more practitioners in exploring new ideas and designs for DF based dialogue systems.

Simplifying Semantic Annotations of SMCalFlow
SMCalFlow is a large corpus of semantically detailed annotations of task-oriented natural dialogues. The annotations use a dataflow approach, in which the annotations are programs which represent user requests. Despite t…

Dataflow Dialogue Generation
We demonstrate task-oriented dialogue generation within the dataflow dialogue paradigm. We show an example of agenda driven dialogue generation for the MultiWOZ domain, and an example of generation without an agenda for …
Dialogue GenerationTranslationTask-Oriented Dialogue as Dataflow Synthesis
We describe an approach to task-oriented dialogue in which dialogue state is represented as a dataflow graph. A dialogue agent maps each user utterance to a program that extends this graph. Programs include metacomputati…
DFEE: Interactive DataFlow Execution and Evaluation Kit
DataFlow has been emerging as a new paradigm for building task-oriented chatbots due to its expressive semantic representations of the dialogue tasks. Despite the availability of a large dataset SMCalFlow and a simplifie…
