How to create a CGI
- Open the GCIs tab next to the "New Concept" tab. If the option is not present this means that the project is not configured to use advanced Description Logic, check with the Project Manager.
- Click on the plus ( + ) icon to enter Edit mode for a new GCI:
- To start the definition of the class expressions on the GCI drop a concept on the left and right hand side, and select the operator type, in this case "subclass of":
- Click on refine on the Left Hand Side to specify an expression, attributes are added just like authoring a normal concept, for example:
- Managing a large set of GCIs can be challenging so it is possible to group GCIs in some meaningful categories, in order to understand the use case behind the axiom. These groups have no logical meaning and is not represented in OWL, it is only an organization tool for authors.
- Click on the Green button to confirm the new GCI
- The GCIs are listed, and the groups of related GCIs can be expanded or collapsed. The GCIs list can also be viewed as Compositional Grammar expressions
- The GCI will be converted to OWL and sent to the Classifier on the next classification run.
