On the Robustness of Dialogue History Representation in Conversational Question Answering: A Comprehensive Study and a New Prompt-based Method

1 code implementation29 Jun 2022 Zorik Gekhman, Nadav Oved, Orgad Keller, Idan Szpektor, Roi Reichart

We find that high benchmark scores do not necessarily translate to strong robustness, and that various methods can perform extremely differently under different settings.

KoBE: Knowledge-Based Machine Translation Evaluation

1 code implementation Findings of the Association for Computational Linguistics 2020 Zorik Gekhman, Roee Aharoni, Genady Beryozkin, Markus Freitag, Wolfgang Macherey

Our approach achieves the highest correlation with human judgements on 9 out of the 18 language pairs from the WMT19 benchmark for evaluation without references, which is the largest number of wins for a single evaluation method on this task.
