EvalSense: A Framework for Domain-Specific LLM (Meta-)Evaluation

arXiv:2602.18823v1 Announce Type: new Abstract: Robust and comprehensive evaluation of large language models (LLMs) is essential for identifying effective LLM system configurations and mitigating risks associated with deploying LLMs in sensitive domains. However, traditional statistical metrics are poorly suited to open-ended generation tasks, leading to growing reliance on LLM-based evaluation methods. These methods, while often more flexible, introduce additional complexity: they depend on carefully chosen models, prompts, parameters, and evaluation strategies, making the evaluation process prone to misconfiguration and bias. In this work, we present EvalSense, a flexible, extensible framework for constructing domain-specific evaluation suites for LLMs. EvalSense provides out-of-the-box support for a broad range of model providers and evaluation strategies, and assists users in selecting and deploying suitable evaluation methods for their specific use-cases.

arXiv:2602.18823v1 Announce Type: new Abstract: Robust and comprehensive evaluation of large language models (LLMs) is essential for identifying effective LLM system configurations and mitigating risks associated with deploying LLMs in sensitive domains.

These methods, while often more flexible, introduce additional complexity: they depend on carefully chosen models, prompts, parameters, and evaluation strategies, making the evaluation process prone to misconfiguration and bias. In this work, we present EvalSense, a flexible, extensible framework for constructing domain-specific evaluation suites for LLMs. EvalSense provides out-of-the-box support for a broad range of model providers and evaluation strategies, and assists users in selecting and deploying suitable evaluation methods for their specific use-cases. This is achieved through two unique components: (1) an interactive guide aiding users in evaluation method selection and (2) automated meta-evaluation tools that assess the reliability of different evaluation approaches using perturbed data. We demonstrate the effectiveness of EvalSense in a case study involving the generation of clinical notes from unstructured doctor-patient dialogues, using a popular open dataset. All code, documentation, and assets associated with EvalSense are open-source and publicly available at https://github.com/nhsengland/evalsense.

Executive Summary

The article introduces EvalSense, a framework designed to address the challenges of evaluating large language models (LLMs) in domain-specific contexts. Traditional evaluation metrics are inadequate for open-ended tasks, leading to a reliance on LLM-based evaluation methods that are complex and prone to misconfiguration and bias. EvalSense offers a flexible and extensible solution with out-of-the-box support for various model providers and evaluation strategies. It includes an interactive guide for method selection and automated meta-evaluation tools to assess the reliability of evaluation approaches. The framework's effectiveness is demonstrated through a case study involving clinical note generation from unstructured doctor-patient dialogues, using a popular open dataset. The code and documentation are open-source and publicly available.
