NIST is pleased to introduce the MetricsMATR Challenge, a new series of research challenge events for machine translation (MT) metrology promoting the development of innovative, even revolutionary, MT metrics. MetricsMATR focuses entirely on MT metrics.
NIST has been conducting formal evaluations of machine translation (MT) technology since 2002, and while the evaluations have been successful, there is still a need for a better understanding of exactly how useful the state-of-the-art technology is, and how to best interpret the scores reported during evaluation.
This need exists primarily due to the shortcomings with the current methods employed for the evaluation of Machine Translation technology:
These problems, and the need to overcome them through the development of improved automatic (and even semi-automatic) metrics, have been a constant point of discussion at past NIST MT evaluations. Without more appropriate metrics to address these shortcomings, the impact of formative and summative MT technology evaluations will remain limited.
NIST is running a new MT evaluation series "MetricsMATR" designed to address this need for improved, even revolutionary, MT metrics.
More details regarding this evaluation can be found on the MetricsMATR home page.
The Metrics MATR evaluation set is composed of data from different sources. It has several language pairs, data genres, and human assessment types.
This report includes 39 metrics, including 7 baseline metrics. More details are available on the metrics page.
