What is Data Annotation?
Data annotation is a process of adding meaning and structure to data so that it can be understood and used by computers. This is done by creating metadata, or data about data, that describes the characteristics of each individual data point. This information can then be used for tasks like data mining and predictive modeling.
Annotated data can also be easier to understand and use by humans. By adding annotations, you can make sure your data is organized and meaningful, making it easier to work with in the future.
