Alvin Po-Chun Chen, Rohan Das, Dananjay Srinivas, Alexandra Barry, Maksim Seniw, Maria Leonor Pacheco
| Challenge: | NLP-assisted systems to support qualitative data analysis have gained considerable traction, but no unified evaluation framework exists to account for the many different settings in which qualitative researchers may employ them. |
| Approach: | They propose a framework to evaluate the way collaboration settings may produce different research outcomes across a variety of interactive systems. |
| Outcome: | The proposed framework evaluates the impact of synchronous vs. asynchronous collaboration on consistency, cohesiveness, and correctness of qualitative research outcomes. |
A Structured Clustering Approach for Inducing Media Narratives (2026.acl-long)
Copied to clipboard
| Challenge: | Existing approaches to modeling media narratives miss subtle narrative patterns through coarse-grained analysis or require domain-specific taxonomies that limit scalability. |
| Approach: | They propose a framework for inducing rich narrative schemas by jointly modeling events and characters via structured clustering. |
| Outcome: | The proposed framework produces explainable narrative schemas that align with established framing theory while scaling to large corpora without exhaustive manual annotation. |
