Simplified text is known to improve the quality of machine translation output. Wikipedia and its simplified counterpart, Simple English Wikipedia, have been used extensively in datasets designed to capitalize on this. However, Simple English Wikipedia has previously been found to be unreliable as a simplified corpus. In this work, passages from the original Wikipedia and Simple English Wikipedia were machine translated by two neural systems, Google Translate and DeepL, and the output evaluated by human judges: firstly for quality, and secondly for comprehensibility using cloze procedure, an uncommon method. No differences were found in output. A corpus analysis of the source texts yielded few signs of simplification. These findings support previous studies showing that Simple English Wikipedia cannot be relied upon as a simplified corpus. Results also showed DeepL to be the best performing system and cloze procedure to be a suitable evaluation protocol for comprehensibility.
