Labeling Experience

Multilingual Chatbot Training Project

TextText Generation

I worked on a multilingual chatbot training project where I helped organize and label conversation data in both English and French. My role involved reviewing chats, identifying user intentions, tagging responses correctly, and checking the quality of the annotations before submission. The project was aimed at helping AI systems better understand human communication and provide more accurate responses during conversations. I also followed detailed annotation guidelines to ensure consistency and accuracy throughout the project. This experience improved my attention to detail, communication skills, and ability to work with large datasets under deadlines.
