1. WHAT ARE SEMANTIC

ANNOTATIONS?

Annotations can be simply seen as “attaching data to some other piece of data”, e.g. documents, web pages, parts of text of web pages; the advantage of a semantic annotation is to have this data formally defined and machine-understandable. This offers better possibility for search, reuse and exploitations of the annotations performed by users.

SEMANTIC ANNOTATION

http://lucadex.blogspot.it/2015/02/the-importance-of-being-semantic.html

‣ Simply speaking it consists of a triple with:

‣ A. the information that is annotated (subject);

‣ B. the content of the annotation itself (object);

‣ C. a predicate, that establishes a relationship amongst the two points above (predicate);

‣ We also have the context in which the annotation has been made (who made it, when, with which instrument, etc). (metadata)

‣ This holds true for all kinds of annotation, including handwritten notes beside paper documents.
