Preface Many Asian countries are rapidly growing these days and the importance of communicating and exchanging the information with these countries has intensified. To satisfy the demand for communication among these countries, machine translation technology is essential. Machine translation technology has rapidly evolved recently and it is seeing practical use especially between European languages. However, the translation quality of Asian languages is not that high compared to that of European languages, and machine translation technology for these languages has not reached a stage of proliferation yet. This is not only due to the lack of the language resources for Asian languages but also due to the lack of techniques to correctly transfer the meaning of sentences from/to Asian languages. Consequently, a place for gathering and sharing the resources and knowledge about Asian language translation is necessary to enhance machine translation research for Asian languages. The Workshop on Machine Translation (WMT), the world’s largest machine translation workshop, mainly targets on European languages and does not include Asian languages. The International Workshop on Spoken Language Translation (IWSLT) has spoken language translation tasks for some Asian languages using TED talk data, but these is no task for written language. The Workshop on Asian Translation (WAT) is an open machine translation evaluation campaign focusing on Asian languages. WAT gathers and shares the resources and knowledge of Asian language translation to understand the problems to be solved for the practical use of machine translation technologies among all Asian countries. WAT is unique in that it is an "open innovation platform": the test data is fixed and open, so participants can repeat evaluations on the same data and confirm changes in translation accuracy over time. WAT has no deadline for the automatic translation quality evaluation (continuous evaluation), so participants can submit translation results at any time. Following the success of the previous WAT workshops (WAT2014, WAT2015), WAT2016 brings together machine translation researchers and users to try, evaluate, share and discuss brand-new ideas about machine translation. For the 3rd WAT, we proudly include new Asian languages: Hindi and Indonesian in addition to Japanese, Chinese and Korean for the machine translation evaluation shared tasks. We had 15 teams who submitted their translation results, and more than 500 submissions in total. In addition to the shared tasks, WAT2016 also feature scientific papers on topics related to the machine translation, especially for Asian languages. The program committee accepted 7 papers that cover wide variety of topics such as neural machine translation, simultaneous interpretation, southeast Asian languages and so on. We are indebted to Hideto Kazawa (Google) who gave an invited talk. We are grateful to "SunFlare Co., Ltd.", "TOIN Corporation", "Baobab, Inc". "Asia-Pacific Association for Machine Translation (AAMT)" and "PostEdit.Tokyo Co., Ltd." for partially sponsoring the workshop. We would like to thank all the authors who submitted papers. We express our deepest gratitude to the committee members for their timely reviews. We also thank the COLING 2016 organizers for their help with administrative matters. WAT2016 Organizers iii
