Our synthesis reveals a growing demand for more rigorous, causal evaluation. By outlining the state of the art and identifying key challenges, this survey provides a roadmap for future research toward making models more transparent.

This survey has been accepted at @blackboxnlp.bsky.social at EMNLP

We consider concept descriptions in open-vocabulary settings, the evolving landscape of automated and human metrics for evaluating them, and the datasets that underpin this research.

This is a companion paper to our PRISM paper that was accepted at NeurIPS last week: bsky.app/profile/lkop...

We investigate how rationale generation is affected by readability level control, and find that explanations are adaptable, but the observed distinction between readability levels does not fully match the desired complexity.
