Overview of the IWSLT 2012 Evaluation Campaign
open5siWe report on the ninth evaluation campaign organized by
the IWSLT workshop. This year, the evaluation offered multiple
tracks on lecture translation based on the TED corpus, and
one track on dialog translation from Chinese
to English based on the Olympic trilingual corpus.
In particular, the TED tracks included a speech transcription
track in English, a speech translation track from English to French,
and text translation tracks from English to French and from Arabic
to English. In addition to the official tracks, ten unofficial
MT tracks were offered that required translating TED talks into English
from either Chinese, Dutch, German, Polish, Portuguese (Brazilian), Romanian, Russian, Slovak,
Slovene, or Turkish.
16 teams participated in the evaluation and submitted a total of 48 primary runs.
All runs were evaluated with objective metrics, while runs of the official translation
tracks were also ranked by crowd-sourced judges.
In particular, subjective ranking for the TED task was performed on a progress test which permitted
direct comparison of the results from this year against the best results from the 2011 round of the evaluation campaign.Marcello Federico; Mauro Cettolo; Luisa Bentivogli; Michael Paul; Sebastian StükerFederico, Marcello; Cettolo, Mauro; Bentivogli, Luisa; Michael, Paul; Sebastian, Stüke
