MultiMirror is a cross-lingual sense projection approach for multilingual WSD based on a novel discriminative word alignment model, capable of jointly aligning all source and target tokens with each other, surpassing its competitors across several language combinations. The sense-tagged datasets it produces lead a standard WSD classifier to achieve state-of-the-art performances on established benchmarks in French, German, Italian, Spanish and Japanese. MultiMirror was developed by the Sapienza Natural Language Processing Group (Sapienza NLP) and the ELEXIS project.
