Translation Error Rate (TER) is a method used by Machine Translation specialists to determine the amount of Post-Editing required for machine translation jobs. The automatic metricmeasures the number of actions required to edit a translated segment inline with one of the reference translations. It’s quick to use, language independent and corresponds with post-editing effort. When tuning your KantanMT engine, we recommend a maximum score of 30%. A lower score means less post-editing is required!
How to use TER in KantanBuildAnalytics™
- The TER scores for your engine are displayed in the KantanBuildAnalytics™ feature. You can get a quick overview or snapshot in the summary tab. But for a more in depth analysis and to calculate the amount of post-editing required for the engine’s MT output select the ‘TER Score’ tab, which takes youto the ‘TER Scores’ page.
- Place your cursor on the ‘TER Scores Chart’ to see the ‘Translation Error Rate’for each segment. If you hold the cursor over the segment, a pop-up will appear on your screen with details of each segment under these headings, ‘Segment no.’, ‘Score’, ‘Source’, ‘Reference/Target’ and ‘KantanMT Output’.
- To see a breakdown of the ‘TER Scores’ foreach segment in a table format scroll down. You will now see a table with the headings ‘No’, ‘Source’, ‘Reference/Target’, ‘KantanMT Output’ and ‘Score’.
- To see an even more in depth breakdown of a particular ‘Segment’ click on the ‘Triangle’ beside each number.
- To download the ‘TER Scores’ of all segments click on the ‘Download’ button on the ‘TER Scores’ page.
