Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on refining the project's documentation across multiple languages. It streamlines the README files by removing obsolete demo instructions and significantly expands the content related to data quality metrics and advanced agent-based evaluation techniques. The updates aim to provide a more current, detailed, and user-friendly guide to the project's core functionalities.

Highlights

• Documentation Cleanup: Outdated sections related to GUI Visualization, Online Demo, Local Demo, and Google Colab Demo were removed from the main README.md and its Japanese and Chinese localized versions.
• Enhanced Data Quality Metrics Section: A comprehensive 'Data Quality Metrics' section was introduced and positioned prominently in README.md, README_ja.md, and README_zh-CN.md. This section details over 70 evaluation metrics, their categories, use cases, and provides quick usage examples with Python code.
• Agent-Based Evaluation Details (Japanese README): The README_ja.md file received significant updates with new content explaining 'Agent-based evaluation and tools', including two implementation patterns (LangChain-based and Custom Workflow), built-in agents, and practical code examples for customization.

Code Review

This pull request updates the README files in English, Japanese, and Chinese. The changes involve removing outdated demo sections and reorganizing the content to improve readability, notably by moving the "Data Quality Metrics" section higher up. The Japanese README is also updated with new sections about agent-based features to align it with the other versions. My review identifies an issue in the Japanese README where several documentation links incorrectly point to Chinese versions instead of the English ones, which could be confusing for readers. I've suggested corrections to ensure consistency and provide a better user experience.

[gemini-code-assist]

The links for "RAG 評価ガイド", "幻覚検出ガイド", and "事実性評価ガイド" point only to the Chinese versions of the documentation. For consistency and a better user experience for Japanese readers, it would be better to link to the English versions and provide an optional link to the Chinese versions, similar to how it's done for the "VLM レンダリング判定ガイド" on line 250.
