An End-To-End Pipeline From Law Text To Logical Formulas, Aarne Ranta, Inari Listenmaa, Jerrold Soh, Meng Weng (Huang Mingrong) Wong

We propose a pipeline for converting natural English law texts into logical formulas via a series of structural representations. Text texts are first parsed using a formal grammar derived from light-weight annotations. An intermediate representation called assembly logic is then used for logical interpretation and supports translations to different back-end logics and visualisations. The approach, while rule-based and explainable, is also robust: it can deliver useful results from day one, but allows subsequent refinements and variations.
