Relation extraction

This task aims to detect entities and semantic relations between them in e-Health documents. 

It comprises 4 entity types (concept, action, predicate, and reference) and the following relations:

• General relations (6): general-purpose relations between two concepts that have a specific semantic: is-a, same-as, has-property, part-of, causes, and entails.
• Contextual relations (3): allow a concept to be refined by attaching the modifiers: in-time, in-place, and in-context.
• Action roles (2): indicate which concepts play a role related to an Action, which can be subject and target.
• Predicate roles (2): indicate concepts play a role in relation to a Predicate, which can be the domain and additional arguments.
