  1. Faster is not always better,but what if it’s not worse? Joke Daems & Lieve Macken http://lt3.hogent.be/en/projects/robot/

  2. Main questions • Is MT+PE more productive than HT? • Is there a difference in quality between MT+PE and HT? Joke Daems: ROBOT

  3. Overview • Experiment set-up • Analysis • Productivity • TQA approach • Results • Productivity • Quality • Conclusion & Future work Joke Daems: ROBOT

  4. Overview • Experiment set-up • Analysis • Productivity • TQA approach • Results • Productivity • Quality • Conclusion & Futurework Joke Daems: ROBOT

  5. Experiment set-up • Participants: Master’s students of translation • 17% never used MT • 61% sometimes used MT • Task: HT & MT+PE (Google Translate) EN->NL • Texts: 4 newspaper articles ± 270 words • Tools: PET & external resources Joke Daems: ROBOT

  6. The PET-tool Joke Daems: ROBOT

  7. Overview • Experiment set-up • Analysis • Productivity • TQA approach • Results • Productivity • Quality • Conclusion & Futurework Joke Daems: ROBOT

  8. Analysis: TQA-approach Joke Daems: ROBOT

  9. TQA-approach: Acceptability Joke Daems: ROBOT

  10. TQA-approach: Adequacy Joke Daems: ROBOT

  11. TQA: Annotation (brat-tool) 1) Acceptability 2) Adequacy Joke Daems: ROBOT

  12. Inter-annotator agreement • 2 annotators • Assessing quality = highly subjective • Acceptability: agreement = 38%; κ = 0.31 • Adequacy: agreement = 41%; κ = 0.30 Joke Daems: ROBOT

  13. Inter-annotator agreement • Correlation between annotators • Acceptability: r = 0.70 • Adequacy: r = 0.89 • Agreement on categories • Acceptability: agreement = 89%; κ = 0.88 • Adequacy: agreement = 89%; κ = 0.87 • Increase after consolidation phase • Acceptability: agreement = 69%; κ = 0.67 • Adequacy: agreement = 82%; κ = 0.79 Joke Daems: ROBOT

  14. Overview • Experiment set-up • Analysis • Productivity • TQA approach • Results • Productivity • Quality • Conclusion & Futurework Joke Daems: ROBOT

  15. Results: Productivity Joke Daems: ROBOT

  16. Overview • Experiment set-up • Analysis • Productivity • TQA approach • Results • Productivity • Quality • Conclusion & Futurework Joke Daems: ROBOT

  17. Results: Quality Joke Daems: ROBOT

  18. Results: Quality Joke Daems: ROBOT

  19. Results: Quality Joke Daems: ROBOT

  20. Results: Quality Joke Daems: ROBOT

  21. Results: Quality Proportion of total per subcategory: focus on acceptability Joke Daems: ROBOT

  22. Overview • Experiment set-up • Analysis • Productivity • TQA approach • Results • Productivity • Quality • Conclusion & Futurework Joke Daems: ROBOT

  23. Conclusions • 2-step TQA approach works • Quality is text-dependent • PE is faster than HT • PE quality often higher than HT quality • Different types of errors between PE and HT Joke Daems: ROBOT

  24. Future work • Link translation problems to source text and MT • Better understanding of PE • Better understanding of translatability • Train post-editors • Repeat experiment with professional translators Joke Daems: ROBOT
