What is Data Annotation?

The process of labelling data to train AI and machine learning models is known as data annotation. It entails adding metadata to a variety of data formats, including text, photos, audio, video, and 3D LiDAR, in order to aid AI systems in correctly understanding and applying the data. The effectiveness and accuracy of artificial intelligence data annotation such as autonomous vehicles, speech recognition, object identification, natural language processing, and more are improved by properly annotated data.
