Currently, only the New Event Detection task is monolingual. The
evaluation plan is the authoritative resource. We limited the language
domain for NED to English for a couple reasons:
1. The task is very difficult and there's sufficient room for
improvement in the monolingual setting.
2. The number of target new events, one per annotated topic, is small a
set of trails. If we were to do a multilingual version, the set of
topics with English first stories would be reduced and the topics with
Mandarin or Arabic would be even smaller.
Do you still think cross-lingual NED would be a valid task? Remember
we'll only have 60 new topics in the TDT4 collection. If I were to
speculate about the likelihood of a non-English first story, it would be
very small.
