Pronominal anaphora resolution in the KANTOO multilingual machine translation system.

We present an approach to pronominal anaphora resolution using KANT Controlled Language and the KANTOO multilingual MT system. Our algorithm is based on a robust, syntax-based approach that applies a set of restrictions and preferences to select the correct antecedent. We report a success rate of 93.3% on a training corpus with 286 anaphors, and 88.8% on held-out data with 144 anaphors. Our approach translates anaphors to Spanish with 97.9% accuracy and to German with 94.4% accuracy on held-out data.
