Comparison of OWL verbalisers. ‘TBox’ contains the ontology’s classes and properties; ‘ABox’ contains the individuals and the assertions upon them. Coverage is approximate: for instance, ACE and SWAT cover nearly all of OWL-2, but with a few omissions. ‘Lexicon’ indicates the source of lexical entries for atomic entities; ‘Domain’ is generic if the system can produce text for any ontology (of the stated OWL coverage) with English-based names, and specific if handcrafted lexical entries or grammar rules are needed.
