Data annotation is the process of labeling raw data like text, images, audio, or video to help machine learning models learn patterns and improve decision-making. It is essential for AI development because it allows models to identify objects, comprehend language, recognize speech, and detect movements. While some companies manage annotation internally, collaborating with specialized firms can streamline operations and enhance outcomes. Key annotation types include Named Entity Recognition and sentiment analysis, which improve AI's language comprehension for applications such as chatbots and search functionalities.
Machine learning models lack the ability to learn from unstructured data, which is essential for them to make predictions and enhance accuracy.
Data annotation assigns labels to raw data, enabling machine learning systems to detect patterns and make informed decisions.
While some companies conduct data annotation in-house, leveraging specialized firms or automated tools can optimize results and expand operational capacity.
Text annotation types like Named Entity Recognition and sentiment analysis enhance AI's understanding of language, crucial for applications like chatbots and search engines.
