This paper addresses the challenges of evaluating document-level machine translation (MT) in the context of recent advances in context-aware neural machine translation (NMT). It investigates how well online MT systems deal with six context-related issues, namely lexical ambiguity, grammatical gender, grammatical number, reference, ellipsis, and terminology, when a larger context span containing the solution for those issues is given as input. Results are compared to the translation outputs from the online ChatGPT. Our results show that, while the change of punctuation in the input yields great variability in the output translations, the context position does not seem to have a great impact. Moreover, the GPT model seems to outperform the NMT systems but performs poorly for Irish. The study aims to provide insights into the effectiveness of online MT systems in handling context and highlight the importance of considering contextual factors in evaluating MT systems.
