|Full name of the tool=Sigma Knowledge Engineering Environment&lt;br /&gt;
|Description of the tool=Sigma knowledge engineering system is an system for developing, viewing and debugging theories in first order logic. It works with Knowledge Interchange Format (KIF) and is optimized for the Suggested Upper Merged Ontology (SUMO) www.ontologyportal.org&lt;br /&gt;
