Instance Selection for Online Automatic Post-Editing in a multi-domain scenario

Rajen Chatterjee, Mihael Arcan, Matteo Negri, Marco Turchi
2016 Conference of the Association for Machine Translation in the Americas  
In recent years, several end-to-end online translation systems have been proposed to successfully incorporate human post-editing feedback in the translation workflow.  ...  The performance of these systems in a multi-domain translation environment (involving different text genres, post-editing styles, machine translation systems) within the automatic post-editing (APE) task  ...  These systems mainly follow the phrase-based machine translation approach where the MT outputs (with optionally the source sentence) are used as the source language corpus and the post-edits are used as  ...

A Novel Rule Refinement Method for SMT through Simulated Post-Editing [chapter]

Sitong Yang, Heng Yu, Qun Liu
2014 Communications in Computer and Information Science  
Post-editing has been successfully applied to correct the output of MT systems to generate better translation, but as a downstream task its positive feedback to MT has not been well studied.  ...  In this paper, we present a novel rule refinement method which uses Simulated Post-Editing (SiPE) to capture the errors made by the MT systems and generates refined translation rules.  ...  Acknowledgement We thank the three anonymous reviewers for helpful suggestions.
