Axiom AITextEntity Ner ClassificationClassification
In this project, I led a team to annotate and classify text and audio data for a healthcare chatbot designed to assist patients with medical inquiries. The project required precise labeling of medical terms using Named Entity Recognition (NER) and accurate transcription of audio consultations. We processed thousands of interactions to improve the chatbot's understanding of patient queries and medical terminology. The project adhered to strict data privacy regulations, and our work improved the chatbot's accuracy by 30%, enhancing patient engagement and satisfaction.
