document annotation

Document annotation involves adding notes, labels, or markers to a text to highlight important information, clarify meaning, or categorize content. This process helps computers understand and process the text more effectively, enabling tasks like extracting key details, identifying themes, or training language models. For example, highlighting names, dates, or opinions within a report makes it easier to analyze or retrieve specific information later. Annotation is used in various fields such as research, machine learning, and data analysis to improve how we interpret and work with text.
