Abstract Meaning Representation for Gesture

no code implementations LREC 2022 Richard Brutti, Lucia Donatelli, Kenneth Lai, James Pustejovsky

This paper presents Gesture AMR, an extension to Abstract Meaning Representation (AMR), that captures the meaning of gesture.

Common Ground Tracking in Multimodal Dialogue

1 code implementation26 Mar 2024 Ibrahim Khebour, Kenneth Lai, Mariah Bradford, Yifan Zhu, Richard Brutti, Christopher Tam, Jingxuan Tu, Benjamin Ibarra, Nathaniel Blanchard, Nikhil Krishnaswamy, James Pustejovsky

Within Dialogue Modeling research in AI and NLP, considerable attention has been spent on ``dialogue state tracking'' (DST), which is the ability to update the representations of the speaker's needs at each turn in the dialogue by taking into account the past dialogue moves and history.

Intelligent Stress Assessment for e-Coaching

no code implementations3 Nov 2023 Kenneth Lai, Svetlana Yanushkevich, Vlad Shmerko

This paper considers the adaptation of the e-coaching concept at times of emergencies and disasters, through aiding the e-coaching with intelligent tools for monitoring humans' affective state.

Causal Models Applied to the Patterns of Human Migration due to Climate Change

no code implementations3 Nov 2023 Kenneth Lai, Svetlana Yanushkevich

The impacts of mass migration, such as crisis induced by climate change, extend beyond environmental concerns and can greatly affect social infrastructure and public services, such as education, healthcare, and security.

A Two-Level Interpretation of Modality in Human-Robot Dialogue

no code implementations COLING 2020 Lucia Donatelli, Kenneth Lai, James Pustejovsky

We analyze the use and interpretation of modal expressions in a corpus of situated human-robot dialogue and ask how to effectively represent these expressions for automatic learning.

A Dynamic Semantics for Causal Counterfactuals

no code implementations WS 2019 Kenneth Lai, James Pustejovsky

Under the standard approach to counterfactuals, to determine the meaning of a counterfactual sentence, we consider the {``}closest{''} possible world(s) where the antecedent is true, and evaluate the consequent.
