Evaluation Examples Are Not Equally Informative: How Should That Change NLP Leaderboards?

Welcome to the project page for our ACL 2021 paper: Evaluation Examples Are Not Equally Informative: How Should That Change NLP Leaderboards?.

Come chat with us at our poster session on Wednesday, August 4 at 00:00-2:00 UTC+0 (Tuesday, August 3 at 5PM PST).

Abstract

Leaderboards are widely used in NLP and push the field forward. While leaderboards are a straightforward ranking of NLP models, this simplicity can mask nuances in evaluation items (examples) and subjects (NLP models). Rather than replace leaderboards, we advocate a re-imagining so that they better highlight if and where progress is made. Building on educational testing, we create a Bayesian leaderboard model where latent subject skill and latent item difficulty predict correct responses. Using this model, we analyze the ranking reliability of leaderboards. Afterwards, we show the model can guide what to annotate, identify annotation errors, detect overfitting, and identify informative examples. We conclude with recommendations for future benchmark tasks.
