Translation quality statistics
Revision as of 07:50, 13 October 2009 by Francis Tyers (talk | contribs)
This page aims to give an overview of the quality of various translators available in the Apertium platform. Word Error Rate (WER) and Position-independent Word Error Rate (PWER) are measures of post-edition effort. The number gives the expected number of words needed to be corrected in 100 words of running text. So, a WER of 4.7% indicates that in a given 100 words of text, 4.7 of them will need to be corrected by the post-editor.
