Using SWRL built-ins in CNL ontology

The Semantic Web Rule Language (SWRL) is an expressive OWL-based rule language. SWRL extends OWL syntax which allows users to write rules with more powerful deductive reasoning capabilities than OWL alone. SWRL built-ins are one of SWRL’s powerful features, which are predicates to be used to manipulate data values in SWRL rules.

From the latest version, Fluent Editor supports a number of core SWRL built-ins defined in SWRL Built-in Submission. In this post, we will introduce two examples of applying some of SWRL core built-ins to your CNL ontology.

Visualization of Ontology Contents - with Ontology Diagram and SWRL Debugger

From the latest release version, Fluent Editor includes a few new features that enhance visualization of ontology, which can help you navigate through the structure of your ontology more intuitively. Possibility of drawing a diagram of ontology is one of such features. Ontology diagrams graphically express relations between concepts and instances - also the materialized ones. 
Another new feature to be introduced is SWRL debugger. SWRL debugger shows binding of rules that took place during the reasoning process over your ontology. It is presented as a list of all the SWRL rules and bound instances. By running SWRL debugger, you can check how SWRL rules work on your ontology.

In this post, we will look through these two features further.
