L2 writing assistant

The task is framed in the context of second language learning. It consists on  building a translation assistance system rather than a full machine translation system. The L1 expression, a word or phrase, is translated by the system to L2, given the L2 context already present, including right-side context if available. The aim  is to carry the semantics of the L1 fragment over to L2 and find the most suitable L2 expression given the already present L2 context. The task addresses both a core problem of WSD, with cross-lingual context, and a subproblem of Phrase-based Statistical Machine Translation; that of finding the most suitable translation of a word or phrase.
