Conversational Agents with Structured Knowledge @ AKBC 2021

Workshop at AKBC 2021
October 7th, 2021


Conversational agents are increasingly becoming part of our day-to-day life on the phone, in the car and in the living room, performing tasks on our behalf which often require interfacing with various forms of structured knowledge. The goal of this workshop is to shed light and encourage interdisciplinary research on some of the open problems situated on the interface of dialog systems and structured knowledge (e.g., knowledge bases, tables etc.), which is critical to the development of digital assistants like Google Home, Alexa and Siri. Our hope is to help bridge the gap between academic and industry research in this area. Open questions include, but are not limited to:

  • How to enable more natural conversations about structured objects and their properties?
  • How to model the structured context of a conversation?
  • Can we develop dialog systems that can inter-operate across arbitrary knowledge base schemas?
  • How to reason about, model, and make updates to an evolving world / knowledge base in a conversational setting?
  • How to characterize and respond to ambiguous references to entities?
  • How to address acoustic ambiguity in references to KB items in spoken queries?
  • How to segment user speech into meaningful utterances?
  • How do Conversational Agents interact with a Situated KB (e.g., user devices)?
  • How to use knowledge encoded in Pre-trained LMs in Conversational Agents?

Call for Extended Abstracts

We invite the submission of extended abstracts to CASK, describing (i) new unpublished or (ii) relevant recently published research in the field. The workshop will not consist of archival proceedings, and the accepted abstracts will be presented as oral (lightning talks) during the workshop and listed on the website.

To submit an abstract to CASK, please send an email to with the subject line “[CASK ABSTRACT]: here-goes-your-title”. The email should include the following:

  • Extended abstracts in PDF format (2 pages max, not including references), as an attachment. Please make sure to include the complete author list, along with their affiliation(s).
    • We encourage the authors to cite all the relevant and related work(s) in the abstract submission. This won’t count towards the 2 page limit.
  • Name and email of the author who would be presenting the work as a lightning talk. We will reach out with the details of the lightning talk post acceptance.
  • (Optional) Full paper, if the authors have a preprint ready.

Submitted abstracts will undergo a lightweight review process to make sure they are relevant to the workshop, but no official reviews will be sent to authors. All accepted abstracts will be made available prior to the workshop. We also would make the lightning talks accessible post workshop proceedings.

If you require further assistance in participating in the workshop, please let us know and we’ll be in touch to discuss how we can best address your needs.
