Abstract: In common law, lawyers cite facts and legal principles from precedent cases for their arguments in support of their current case. Such facts and principles must be identified, though this is a highly time intensive task. We demonstrate that human annotators can agreement on which sentences are facts or principles. A supervised machine learning framework can automatically annotate sentences containing such legal facts and principles based on linguistic features, reporting precision and recall figures of between 0.79 and 0.89 using a Bayesian classifier.
