SCAI 2021

SCAI 2021

SCAI 2021 is intended as a discussion platform on Conversational AI for intelligent information access, bringing together researchers and practitioners across natural language processing, information retrieval, machine learning and human-computer interaction fields. Among other topics, we will discuss design, evaluation and human factors in relation to automating information-seeking dialogues. The workshop also featured a shared task on Conversational Question Answering.

SCAI is already an established venue with a long-standing tradition of building bridges and integrating expertise from diverse research communities. It was previously organised in the context of ICTIR 2017, EMNLP 2018, TheWebConf 2019, IJCAI 2019 and EMNLP 2020. To access the materials of the previous five editions of SCAI navigate to https://scai-workshop.github.io

While 2021 marks a 6th iteration of SCAI, this year, the workshop now focuses on the discussion between researchers from different fields. It is therefore organized as a strictly non-archival venue, as an opportunity to present papers accepted to other venues in an interdisciplinary meeting specifically focused on search-based conversational AI.

The workshop is organized as an online event, with free participation.
