The POTUS Corpus, a Database of Weekly Addresses for the Study of Stance in Politics and Virtual Agents (2020.lrec-1)
Copied to clipboard
| Challenge: | Embodied Conversational Agents (ECAs) are used to generate socially believable agents. |
| Approach: | They propose to use audio-video files of political addresses to generate a corpus of socially believable agents which can be annotated by external observers. |
| Outcome: | The proposed corpus analyzes audio-video files of political addresses to the american people and provides the same speeches given by a virtual agent named Rodrigue. |
iKnow-audio: Integrating Knowledge Graphs with Audio-Language Models (2025.emnlp-main)
Copied to clipboard
| Challenge: | Contrastive language-audio pretraining models learn by aligning audio and text in a shared embedding space. |
| Approach: | They propose a framework that integrates knowledge graphs with audio-language models to provide robust semantic grounding. |
| Outcome: | iKnow-audio improves disambiguation of acoustically similar sounds and reduces prompt engineering. |
