| Challenge: | This paper reports the first release of the UMR data set for six languages . it includes annotations for six different languages that vary greatly in terms of their linguistic properties and resource availability. |
| Approach: | They report the first release of the UMR data set for six languages . they describe on-going efforts to enlarge the data set and extend it to other languages - including Navajo, Navájo, and Sanapaná . |
| Outcome: | The first release of the UMR data set includes annotations for six languages . the language dataset is available for free and can be extended to other languages if needed . |
Abstract Meaning Representation for Gesture (2022.lrec-1)
Copied to clipboard
| Challenge: | Abstract Meaning Representation (AMR) is an annotated graphbased representation that expresses the meaning of a sentence in terms of its predicate-argument structure. |
| Approach: | They propose an extension to Abstract Meaning Representation (AMR) that captures the meaning of gesture. |
| Outcome: | The proposed model is more challenging than standard AMR while integrating meaningful elements unique to gesture. |

| Challenge: | In dialogue modeling, there is considerable attention on “dialogue state tracking” (DST) but “common ground tracking” identifies the shared belief space held by all participants in a task-oriented dialogue: the task-relevant propositions all participants accept as true. |
| Approach: | They propose a method for automatically identifying the current set of shared beliefs and ”questions under discussion” of a group with a shared goal. |
| Outcome: | The proposed method predicts moves toward building common ground relative to ground truth in a multimodal interaction with an AI. |
Encoding Gesture in Multimodal Dialogue: Creating a Corpus of Multimodal AMR (2024.lrec-main)
Copied to clipboard
| Challenge: | Abstract Meaning Representation (AMR) was designed to represent sentence meaning in English text, but recent research has explored its adaptation to broader domains, including documents, dialogues, spatial information, cross-lingual tasks, and gesture. |
| Approach: | They propose to annotate a multimodal (speech and gesture) AMR corpus in a task-based setting and capture coreference relationships across modalities. |
| Outcome: | The proposed corpus captures coreference relationships across modalities, enabling fine-grained analysis of how gesture and natural language interact. |
A Two-Level Interpretation of Modality in Human-Robot Dialogue (2020.coling-main)
Copied to clipboard
| Challenge: | modal expressions are used to communicate and align world knowledge, but there is no obvious manner to ground them in the shared environment. |
| Approach: | They propose a two-level annotation scheme for modality that captures both content and intent and a task-oriented, pragmatic representation that maps to our robot's capabilities. |
| Outcome: | The proposed model can be grounded and dynamically interpreted. |
