Plain-Language Brief

Researchers have developed a framework for translating natural language descriptions of strategic requirements into well-formed formulas using Large Language Models (LLMs). They created and curated a novel dataset for training and evaluating these models, and their best fine-tuned system matches the performance of strong few-shot proprietary baselines. The generated specifications can be used in an existing strategic logics model checker, allowing non-expert users to specify strategic properties in natural language.

What the Document Says

  • A framework for translating natural language descriptions of strategic requirements into ATL/ATL* formulas is presented using Large Language Models (LLMs).
  • The researchers created and curated a novel dataset for training and evaluating these models.
  • In-domain fine-tuning of small open-weight models (3 - 7B parameters) matches strong few-shot proprietary API baselines on a held-out test set.
  • The best fine-tuned system reaches 0.84 semantic accuracy, statistically on par with 0.86 for the strongest few-shot proprietary baseline.
  • The generated specifications can be used in an existing strategic logics model checker.
  • It's mentioned that the judge reliability is inverse to generator strength.

Raw Abstract / Excerpt

A rigorous formalization of system requirements is a fundamental prerequisite for the verification of Multi-Agent Systems (MAS). However, writing correct formal specifications is well known as an error-prone, time-consuming, and expertise-intensive task. This difficulty is further accentuated in MAS, where requirements must capture strategic abilities and temporal objectives. At present, there is no established methodology for deriving MAS specifications from natural language. We present a framework for translating Natural Language descriptions of strategic requirements into well-formed ATL/ATL* formulas using Large Language Models (LLMs). Since no available dataset supports supervised learning for the NL-to-ATL/ATL* translation task, we create and curate a novel expert-validated dataset, employed for training and evaluating fine-tuned models. On a held-out test set, evaluated under the LLM judge that best agrees with expert annotations, in-domain fine-tuning of small open-weight models (3 - 7B parameters) matches strong few-shot proprietary API baselines. Our best fine-tuned system reaches 0.84 semantic accuracy, statistically on par with 0.86 for the strongest few-shot proprietary baseline, while keeping requirements on-premises. We further find that judge reliability is inverse to generator strength. The open-weight Llama-3.3-70B tracks human verdicts most closely, whereas the strongest proprietary models are the least reliable judges, over-rejecting faithful paraphrases of the reference. To assess the practical applicability of the generated specifications, we embed our tool to an existing strategic logics model checker, enabling non-expert users to specify strategic properties in natural language.
