Supplementary Material, Towards the LLM-Based Generation of Formal Specifications from Natural-Language Contracts: Early Experiments with Symboleo
<p>This repository contains all the files used in the experiments described in the paper "Towards the LLM-Based Generation of Formal Specifications from Natural-Language Contracts: Early Experiments with Symboleo", which appeared in "RAISE 2025: Requirements engineering for AI-powered SoftwarE", an ICSE 2025 workshop, Ottawa, May 3, 2025.</p>
Formal-Specification-to-Code Trace Links Recovery
<p>The experiment data and the code used in our experiments to evaluate the performance of the proposed formal-specification-to-code trace links establishment method, and the other exsiting text-based trace links recovery methods, including Latent Semantic Indexing, Vector Space Model, Word2Vec embeddings, and LLM-based embeddings, are here. It originate from three projects. The first one is an open source VDM-SL specification of an AccountSys and its Java implementation. It comes from the book “Formal Software Development: From VDM to Java” written by Quentin Charatan and Aaron Kans. Both the VDM-SL formal specification and the Java implementation of the AccountSys were developed and provided by Prof. Aaron Kans from University of East London. It illustrates how to model bank accounts and transactions made on these as a series of deposits and withdrawals. Bank.java file implementing the GUI of the system in the source code is not used since it contains syntactical error and cannot build AST. The second project involves the SOFL specification and the Java implementation of an ATM system. The operations on current accounts of an ATM, such as deposit, withdraw, show balance, print out transaction records are specified by using SOFL formal language and implemented by using Java langauge. The third project involves an open source VDM-SL specification of a hotel system along with its C implementation. The specification describes a hotel management system where guests can check in, enter rooms, and manage cards associated with rooms and keys. The VDM-SL specification, created by Daniel Jackson and presented in his book “Software Abstractions: Logic, Language, and Analysis”. </p>

Formal Specification and Verification of a Coordination Protocol for an Automated Air Traffic Control System
We detail all of the facets of adapting classical model checking to a real aerospace system, in- cluding deriving the formal model and a set of specifications from natural language descriptions. To ensure the model checking results are meaningful, we have to ensure that both the model and specifications correctly reflect the intentions of the designers, thus we employ model validation and property debugging techniques. We demonstrate the utility of enhancing LTL satisfiability checking by taking the fairness constraints of the system model into consideration. We argue that specification debugging in real applications deserves more attention in future research efforts, and the utility of a system formalization, model and specification debugging, and verification trilogy for model checking real systems under development. In this paper we assume there are no hardware failures or lost messages. As the AAC design develops and hardware details are decided by AAC designers, we plan to take the failure rates of the chosen components into consideration, i.e. by extending our work to probabilistic model checking using PRISM [19]. Previous work has reported on analyzing the safety of air traffic control systems using simulation [3] or fault trees [1]. By extending the model we designed in this paper, we can carry out safety analysis using PRISM to capture the dynamic interactions in the AAC.
