English AI Content Evaluation Tracker – Personal Project

Text
I launched a personal project for English AI content evaluation, developing a tracker for logging annotation tasks and accuracy. I identified patterns in recurring errors and shared quality insights on GitHub for the annotator community. The project aided in personal calibration and best-practices sharing for QA processes. • Tracked annotation tasks and model feedback • Documented English AI content errors • Provided open-source resources for annotators • Supported self-improvement in annotation quality
