Verifiable Reasoning Evaluation Framework: Quantifying the Reliability of AI Outputs Using Semantic Similarity

This project proposes a research-oriented AI evaluation system—the Verifiable Reasoning Evaluation Framework—which quantifies the reliability of generated answers using semantic similarity and confidence metrics. The framework supports manual input and retrieval+LLM automatic generation modes, provides benchmark datasets, score visualization, and analysis tools, aiming to address the hallucination issue of large language models and improve the factual accuracy and verifiability of AI outputs.

Modern large language models (LLMs) generate fluent text but have factual accuracy flaws and are prone to 'hallucinations', posing challenges in high-risk scenarios. The Verifiable Reasoning Benchmark Evaluation Framework project emerged to provide a systematic quality assessment method for AI-generated content, emphasizing semantic alignment and factual reliability.

The framework adopts a modular pipeline architecture: the input layer receives queries; the optional retrieval module implements semantic retrieval via embedding vectors (supports RAG); the generation module supports manual input or LLM automatic generation; the evaluation engine calculates scores by comparing predictions with standard answers; the visualization layer builds an interactive dashboard based on Streamlit to display results.

• Generator: Integrates OpenAI API and supports context-aware generation;
• Retriever: Computes embeddings based on SentenceTransformers and selects relevant context;
• Evaluation Engine: Compares predictions with real answers sample by sample to generate fine-grained and aggregated scores;
• Metrics Module: Uses cosine similarity to quantify semantic similarity;
• UI: Provides query input, real-time result display, and other functions based on Streamlit.

The framework presets multi-level test scenarios:

• High-quality answers: High semantic alignment, scores close to 1.0;
• Low-quality answers: Irrelevant or incorrect content, significantly lower scores;
• Mixed-quality responses: Partially correct and partially wrong, resulting in medium scores.

1. Modular design facilitates independent iteration and expansion;
2. Dual-mode support for manual and automated evaluation;
3. Optional RAG support for贴近实际应用场景 (close to real application scenarios);
4. Streamlit real-time visualization accelerates evaluation iteration;
5. Open-source friendly (MIT License) to encourage community contributions.

Current Limitations: Semantic similarity does not equal factual correctness, relies on the quality of standard answers, LLM output randomness, simplified retrieval module; Future Directions: Multi-model benchmarking, advanced hallucination detection, citation-level fine-grained verification, dataset-driven pipeline, leaderboard and experiment tracking system.

Provides practical tools for AI researchers, with value reflected in:

1. Verifiability: Offers quantitative quality metrics;
2. Comparability: Standardized process supports fair model comparison;
3. Interpretability: Visualization helps understand model behavior;
4. Practicality: Supports evaluation of real scenarios like RAG. It helps establish a trust mechanism for model outputs and promotes the evolution of AI from 'usable' to 'trustworthy'.
