Abstract

Legal contracts specify requirements for business transactions. Symboleo was recently proposed as a formal specification language for legal contracts. It allows the specification of the contractual requirements by specifying the obligations and powers of the parties, as well as specifying the events that can occur in a contract’s lifecycle. With appropriate tool support, Symboleo can allow monitoring the contract lifecycle. However, because of mistakes in contract interpretation or formal specification, specified contracts may violate properties expected by contracting parties. This paper presents SymboleoPC, a tool for analyzing Symboleo contracts using the nuXmv model checker, where properties can be expressed in both Linear Temporal Logic and Computation Tree Logic. The presentation highlights the architecture, implementation, and testing of the tool, as well as a scalability evaluation, based on performance data. The performance of the tool was evaluated with respect to varying numbers of obligations and powers, with varying numbers of inter-dependencies among them, with parameters derived from the analysis of real contracts. These results suggest that SymboleoPC can be usefully applied to the analysis of formal specifications of contracts with real-life sizes and structures.

SymboleoPC：检查法律合同的属性

法律合同规定了商业交易的要求。最近，Symboleo 被提议作为法律合同的正式规范语言。它通过规定各方的义务和权力，以及规定合同生命周期中可能发生的事件，来规范合同要求。有了适当的工具支持，Symboleo 可以监控合同的生命周期。然而，由于合同解释或形式规范方面的错误，指定的合同可能会违反缔约各方所期望的属性。本文介绍了 SymboleoPC，这是一种使用 nuXmv 模型检查器分析 Symboleo 合同的工具，其中的属性可以用线性时态逻辑和计算树逻辑来表达。演讲重点介绍了该工具的架构、实施和测试，以及基于性能数据的可扩展性评估。根据对真实合同的分析得出的参数，针对不同数量的义务和权力以及它们之间不同数量的相互依赖关系，对该工具的性能进行了评估。这些结果表明，SymboleoPC 可以有效地应用于分析具有实际大小和结构的合同的形式规范。
