    From the advances in neural machine translation (NMT), automatic error classification and predictive quality, to non-stop research on content intelligencelet’s take a glimpse into the future of translation automation. 

    1. 1 - Predictive quality estimation: from theory to practice

    The bilingual evaluation understudy (BLEU) scoring methodology continues to be referenced as a quick and low- cost option to evaluate MT progress.  Developed by MT engineers, it doesn’t require the involvement of translators, but the results imply there is only one correct translation for a given text, when this is obviously not true. The “approved” translation is then set as a reference, in both source and target language, and the evaluation scores are as high as the similarity between the output and reference translation. 

    So, while BLEU usually does correlate with human judgement, it does not answer the real question: how good is the actual machine translated content? 

    Discussions on MT quality metrics are still under way, but the goal is to get to a position where every machine translated content comes with a quality estimation that annotates the MT output and gives it a quality score. It seems unanimous among translation experts that quality can only “truly” be assessed by human review (for now). 

     

    1. 2 - Neural MT: to APE or not to APE

    Automatic Post Editing (APE) for neural MTwhile not new is gaining traction. As it starts to be tested by major ecommerce companies, it’s evolving into a real business possibility. But there’s still a question in the air: is it counter-productive or time saving? 

    APE has followed a similar evolution to machine translation. The aim of an APE system is to correct the mistakes in MT output and generate a "human-like'" post-edited machine translation (PEMT). APE can improve the machine translated content or adapt it to a specific domain. For example, in proprietary systems, it can come in handy as a way to learn from human corrections and avoid recurring errors, teaching the system what not to do. Even with a high-quality MT engine, automatic post editing can help to reduce the human effort on post-editing. 

    APE can also be incorporated into computer-assisted translation (CAT) tools to aid content reviewers in post editing. However, test results of this application have proved it to be counter-productive, as linguists tend to spend less effort on segments that have been rated 90 percent (or more) by the APE tool, and move on to next segment. The problem is that 90 percent score may or may not be accurate. The effort spent by the linguists is reduced, but the quality of the final delivery may be compromised. In summary, although progress continues in the area of predictive and actual quality measures, there’s still a lot more to achieve but progress continues. 

    1. 3 - Crowdsourcing translation: moving between expectations and reality

    Crowd translation first appeared as a solution for startups or nonprofit organizations that needed multilingual content, but had limited localization budgets. Nowadays, crowdsourcing is generally being used in contexts of post-editing machine translation. It can substantially improve the quality of machine translated content, but it can also be challenging in terms of quality monitoring. 

    By inviting a “crowd”, that can be a small group of colleagues or clients, or even the entire online community, text strings can be translated and quality control is carried out by peer-to-peer review – anyone can leave a comment or correction. 

    The risk is that this all depends on the interest and will to collaborate of the crowd members, as well as not knowing if they’re qualified or not. The verdict is that although it’s on a good path, there’s still a long learning curve to overcome. 

     

    The lingering question: Where is technology taking us? 

    Content technologies keep evolving at the speed of light and machine translation is no exception. 

    In today’s business world, global communication takes place in real time. To keep up with this pace, automation is inevitable. Companies all over the world are turning to machine translation to keep up with the constant rise of content volumes and an increasing “global village”. 

    As with any new design, this technological evolution raises interesting questions and dilemmas. Where is content technology taking us? Can we agree on standard metrics for measuring machine translation quality and performance? Can we ensure equal access to data for everyone? How do we manage content integrity? Can machine translation quality really be assessed without human review? Are solutions for voice recognition keeping pace? 

    As a global content solutions partner, we’re excited to be part of this content revolution and continue to help our customers find the ideal technology mix and quality level to communicate effectively with their target audiences worldwide.
