Text annotation can be performed manually, automatically, or through a combination of both:
Manual Annotation: In manual annotation, experts read through texts and apply the necessary tags. This method is time-consuming but often yields high accuracy. Automated Annotation: Automated systems use natural language processing (NLP) algorithms to identify and tag relevant information. While faster, this method may not always be as accurate as manual annotation. Hybrid Annotation: A combination of manual and automated methods is often used to balance speed and accuracy. Automated systems can perform initial tagging, which is then reviewed and corrected by experts.
