The topics for the fourth year of the Conversational Assistance Track (CAsT) have been released: github.com/daltonj/treccastw…
New this year: (1) Different topic format, (2) Mixed-Initiative system responses (3) Complex discourse structures

Check out the first session of @scai_workshop 2022: "Conversational Search Evaluation", where I present a way to evaluate conversational systems by user simulator that predicts users' satisfaction scores along with actions and utterances 🤖🤖
Joint work with @AldoLipani

Excited to announce that I've been promoted to Associate Professor (Senior Lecturer) at @GlasgowCS.
My group, @grill_lab_ai has open positions for PhD/Postdocs on interactive and multimodal foundation models -- grilllab.ai/ #conversationalai

🥁🥁🥁 @IgluContest is about to start! The focus is on building an interactive agent that can understand the instructions in natural language to build structures in the #Minecraft environment! In case of uncertainty, ask clarifying questions! Interested? #SIGIR2022 #NAACL2022

risk-aware policy trained with RL deep q-learning decides to ask a clarifying question based on a user simulator response & future results
session-based evaluation metrics: recall, MRR, decision error rate

limitations of user simulators for conversational search? @JeffD
* lack of multi-turn data with natural long-term trajectories
* personalisation, cultural & language variations
* need for taxonomy & understanding of different system initiative actions

This was my first debut to the @scai_workshop 😊 Thanks for the invitation and valuable questions and discussion!

In the perspectives session, I enjoyed the talk by @krisztianbalog on on natural language user profiles for recommendation, especially how they used a few-shot prompt template to turn a large language model (LaMDA) into a recommender. dl.acm.org/doi/10.1145/34774…

Valeriia Bolotova et al. got the best paper award at #SIGIR2022 for their very extensive paper titled "A Non-Factoid Question-Answering Taxonomy", which I really like because it is such a timeless topic and remains relevant dl.acm.org/doi/10.1145/34774…

🤵♂️I can see myself in the corner :-)
Jokes aside it was a wonderful session. Thanks @scai_workshop and @SIGIRConf for the opportunity, my fellow presenters, session chair, and all the audience for the wonderful discussion at the end of the session.

main challenges for conversational QA? @AldoLipani
* difficulties in evaluation:
* lack of metrics for answer naturalness & facet discovery
* need to measure user satisfaction
* incorporating personalised context
* leveraging non-parametric information sources
