Data Collection

Freelancer Overview

I don’t have professional experience in data labeling yet, but I understand it as the process of tagging or annotating raw data like images, text, audio or video so that machine learning models can learn from it. From what I know, the work usually involves carefully following instructions to label objects correctly, such as identifying things in images or classifying text based on meaning or sentiment. It’s basically helping AI systems understand real-world data through accurate labeling.
