Microsoft AI Evaluations Library: Quality Evaluators Explained
The Microsoft AI Evaluations Library provides a suite of evaluators to systematically assess the quality of AI-generated responses in your projects. These evaluators help ensure that AI outputs meet specific standards of accuracy, relevance, and clarity, making them suitable for production use in intelligent applications12.
Key Evaluators and Their Metrics
| Evaluator | Metric | Description |
|---|---|---|
| RelevanceEvaluator | Relevance | Assesses how well the response addresses the user's query or intent. |
| TruthEvaluator | Truth | Evaluates the factual correctness of the response. |
| CompletenessEvaluator | Completeness | Measures how comprehensive and thorough the response is, ensuring all aspects are covered. |
| FluencyEvaluator | Fluency | Checks for grammatical accuracy, vocabulary usage, sentence complexity, and readability. |
| CoherenceEvaluator | Coherence | Examines the logical flow and organization of ideas in the response. |
| RetrievalEvaluator | Retrieval | Assesses the effectiveness of retrieving and incorporating relevant context or information. |
| EquivalenceEvaluator | Equivalence | Compares the generated response to a reference or ground truth for similarity and alignment. |
| GroundednessEvaluator | Groundedness | Evaluates how well the response is supported by the provided context or source material. |
Why Use These Evaluators?
- Automated Quality Checks: Integrate these evaluators into your development pipeline to automate the assessment of AI responses.
- Customizable: You can implement your own evaluators by extending the provided interfaces, tailoring the evaluation process to your specific needs.
- Comprehensive Coverage: The evaluators cover essential aspects of AI response quality, from factual accuracy to linguistic clarity and contextual alignment13.
Practical Integration
- The library is available as open source and can be integrated into .NET applications.
- It supports use cases like continuous integration (CI/CD) pipelines, ensuring AI models are evaluated before deployment.
- Evaluators leverage large language models (LLMs) to perform assessments, providing scalable and consistent evaluation12.
These tools help developers deliver more reliable, accurate, and user-friendly AI-powered applications by systematically measuring and improving the quality of AI-generated content.
