ScrumSourcing: Challenges of Collaborative Post-editing for Rugby World Cup 2019

This paper describes challenges facing the ScrumSourcing project to create a neural machine translation (NMT) service aiding interaction between Japanese- and English-speaking fans during Rugby World Cup 2019 in Japan. This is an example of «domain adaptation». The best training data for adapting NMT is large volumes of translated sentences typical of the domain. In reality, however, such parallel data for rugby does not exist. The problem is compounded by a marked asymmetry between the two languages in conventions for post-match reports; and the almost total absence of in-match commentaries in Japanese. In post-editing the NMT output to incrementally improve quality via retraining, volunteer rugby fans will play a crucial role in determining a new genre in Japanese. To avoid de-motivating the volunteers at the outset we undertake an initial adaptation of the system using terminological data. This paper describes the compilation of this data and its effects on the quality of the systems’ output.Este documento describe los retos a los que se enfrenta el proyecto ScrumSourcing para crear un servicio de traducción automática neuronal (NMT) que ayude a la interacción entre los aficionados de habla japonesa e inglesa durante la Copa Mundial de Rugby de 2019 en Japón. Este es un ejemplo de «adaptación al dominio». Los mejores datos de entrenamiento para adaptar la NMT son grandes volúmenes de oraciones traducidas típicas del dominio. Sin embargo, en la realidad no existen tales datos paralelos para el rugby. El problema se agrava por una marcada asimetría entre las dos lenguas en las convenciones para los informes posteriores al partido y la ausencia casi total de comentarios emitidos en directo durante el partido en japonés. En la post-edición de la producción de la NMT para mejorar de forma incremental la calidad a través del reentrenamiento, los voluntarios aficionados al rugby desempeñarán un papel crucial en la determinación de un nuevo género en japonés. Para evitar desmotivar a los voluntarios desde el principio, emprenderemos una adaptación inicial del sistema utilizando datos terminológicos. Este documento describe la compilación de estos datos y sus efectos en la calidad de la producción de los sistemas

Getting Past the Language Gap: Innovations in Machine Translation

In this chapter, we will be reviewing state of the art machine translation systems, and will discuss innovative methods for machine translation, highlighting the most promising techniques and applications. Machine translation (MT) has benefited from a revitalization in the last 10 years or so, after a period of relatively slow activity. In 2005 the field received a jumpstart when a powerful complete experimental package for building MT systems from scratch became freely available as a result of the unified efforts of the MOSES international consortium. Around the same time, hierarchical methods had been introduced by Chinese researchers, which allowed the introduction and use of syntactic information in translation modeling. Furthermore, the advances in the related field of computational linguistics, making off-the-shelf taggers and parsers readily available, helped give MT an additional boost. Yet there is still more progress to be made. For example, MT will be enhanced greatly when both syntax and semantics are on board: this still presents a major challenge though many advanced research groups are currently pursuing ways to meet this challenge head-on. The next generation of MT will consist of a collection of hybrid systems. It also augurs well for the mobile environment, as we look forward to more advanced and improved technologies that enable the working of Speech-To-Speech machine translation on hand-held devices, i.e. speech recognition and speech synthesis. We review all of these developments and point out in the final section some of the most promising research avenues for the future of MT
