SymboleoNLP: A Tool for Generating Formal Specifications from Legal Contract Templates

Abstract

SymboleoNLP is a Web-based tool that allows contract authors to make customizations to a legal contract template using a controlled, yet expressive, natural language. The tool also maintains a formal specification of the contract in Symboleo, a formal specification language designed for the legal contract monitoring domain. The controlled customizations allow for the automated formalization of the customized contract, enabling Symboleo-based property verification and code generation of monitoring smart contracts. This work pushes the boundaries of requirements-based contract template customization with a view towards full formalization.
