| 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. |

| Challenge: | Uniform Meaning Representation (UMR) is a graphbased cross-linguistically applicable semantic representation that allows for deep semantic analysis. |
| Approach: | They propose to use an aspectual lattice to adapt to different languages and design values that encompass both viewpoint aspect and situation aspect. |
| Outcome: | The proposed representations are based on the Chinese version of The Little Prince and are compared with other representations. |
