Labeling Experience

Structured Dataset Creation for FAQ Chatbot (Project)

TextQuestion Answering

I curated and labeled over 500 question-answer pairs, designing a structured annotation schema for an FAQ chatbot dataset. This involved creating high-quality, accurate pairings aligned with project goals. Rigorous documentation and adherence to annotation processes were maintained throughout. • Labeled and verified question-answer datasets for chatbot systems. • Developed annotation schema and documentation for dataset reliability. • Ensured consistency and accuracy in labeled Q&A pairs. • Contributed to the dataset used for conversational AI development.
