Using ALLiS for Clausing

Hervé Déjean

We present the result of a symbolic machine learning system, ALLiS 2.0 for the CoNLL-2001 shared task. ALLiS 2.0 is a theory refinement system using hierarchical data. Results are F=89.04 for subtask 1, F=68.02 for subtask 2 and F=67.70 for subtask 3 (development test). Adding manual rules improves considerably results specially for task 2 (F=79.44). For the test data, results are slightly worse (F=62.27 for subtask 3).
