Alex Rudnick, Levi King, Can Liu, Markus Dickinson, Sandra Kübler · 2014
We describe the Indiana University system for SemEval Task 5, the L2 writing assistant task, as well as some extensions to the system that were completed after the main evaluation.Our team submitted translations for all four language pairs in the evaluation, yielding the top scores for English-German.The system is based on combining several information sources to arrive at a final L2 translation for a given L1 text fragment, incorporating phrase tables extracted from bitexts, an L2 language model, a multilingual dictionary, and dependency-based collocational models derived from large samples of targetlanguage text.
