Title: A Dataset for Statutory Reasoning in Tax Law Entailment and Question Answering
Authors: Nils Holzenberger, Andrew Blair-Stanek, Benjamin Van Durme
Abstract summary: This paper investigates the performance of natural language understanding approaches on statutory reasoning. We introduce a dataset, together with a legal-domain text corpus. We contrast this with a hand-constructed Prolog-based system, designed to fully solve the task.

Abstract: Legislation can be viewed as a body of prescriptive rules expressed in natural language. The application of legislation to facts of a case we refer to as statutory reasoning, where those facts are also expressed in natural language. Computational statutory reasoning is distinct from most existing work in machine reading, in that much of the information needed for deciding a case is declared exactly once (a law), while the information needed in much of machine reading tends to be learned through distributional language statistics. To investigate the performance of natural language understanding approaches on statutory reasoning, we introduce a dataset, together with a legal-domain text corpus. Straightforward application of machine reading models exhibits low out-of-the-box performance on our questions, whether or not they have been fine-tuned to the legal domain. We contrast this with a hand-constructed Prolog-based system, designed to fully solve the task. These experiments support a discussion of the challenges facing statutory reasoning moving forward, which we argue is an interesting real-world task that can motivate the development of models able to utilize prescriptive rules specified in natural language.
