Data Annotation Services

At Corro Vista, this involves labelling data, such as images, text, or audio, to make it usable for machine learning models. For example, annotating images with bounding boxes to identify objects within them. 

This includes adding comments, highlights, or notes to documents for review or collaboration purposes. Tools like Adobe Acrobat or Microsoft Word offer such features.

In programming, annotations are used to provide metadata about the code. For instance, in Java, annotations like @Override or @Deprecated provide information about the methods.

In the context of the Spring Framework, annotations like @Service are used to indicate that a class provides some business functionalities. This helps in organizing the code and making it more readable and maintainable.
