Reference-less Measure of Faithfulness for Grammatical Error Correction
Leshem Choshen, Omri Abend
We propose USim, a semantic measure for Grammatical Error Correction (GEC) that measures the semantic faithfulness of the output to the source, thereby complementing existing refer…
Automatic Metric Validation for Grammatical Error Correction
Leshem Choshen, Omri Abend
Metric validation in Grammatical Error Correction (GEC) is currently done by observing the correlation between human and metric-induced rankings. However, such correlation studies…

DORA The Explorer: Directed Outreaching Reinforcement Action-Selection
Leshem Choshen, Lior Fox, Yonatan Loewenstein
Exploration is a fundamental aspect of Reinforcement Learning, typically implemented using stochastic action-selection. Exploration, however, can be more efficient if directed towa…
Inherent Biases in Reference based Evaluation for Grammatical Error Correction and Text Simplification
Leshem Choshen, Omri Abend
The prevalent use of too few references for evaluating text-to-text generation is known to bias estimates of their quality ({\it low coverage bias} or LCB). This paper shows that o…
