AccuracyScorer
Calculates accuracy based on substring or token-level matching between prediction and ground truth. More lenient than ExactMatchScorer, allowing for partial matches.
Overview
Calculates accuracy based on substring or token-level matching between prediction and ground truth. More lenient than ExactMatchScorer, allowing for partial matches.
Use Cases
- Accuracy benchmarking and validation
How It Works
This scorer uses LLM-as-Judge technology to evaluate responses. It prompts a large language model with specific evaluation criteria and the content to assess, then analyzes the LLM's judgment to produce a score and detailed reasoning.
