Annotations available in Qanary

The following list shows which are the annotations available in the Qanary vocabulary, i.e. the information that can be shared across components in a QA pipeline. The Qanary vocabulary extends the WADM and reuses his vocabulary. For more information about the WADM look under the following link.

Note: The Qanary vocabulary is designed to be extensible it is possible at any time to add new types of annotations. We follow the idea that the communication standard between components should not be fixed ones but must evolve according to the needs of the QA community. So if a new type of annotation is needed this should be added by extending the Qanary vocabulary.
