The author is engaged in the modernization of public benefit delivery. In particular the author is exploring the potential of the “Rules as Code” approach of legal knowledge represen- tation and reasoning for that purpose. The authors have un- dertaken a textual data analysis of a federal benefits statute, Canada’s Old Age Security Act. This analysis is designed to assess the prevalence of certain types of expressions used in statutory drafting, and give insights into the corresponding importance of those styles of expression in a Rules as Code tool. The analysis is a work in progress, and is shared in the hope of obtaining feedback on how to improve it.
