DESCRIPTION:Committee:  Drs. Pascal Hitzler\, Advisor\, Mateen Rizki\, and 
 Yong PeiABSTRACT:One hotly debated research topic is\, 'What is the best a
 pproach for modeling ontologies?' In the earlier stages of modeling ontolo
 gies\, researchers have favored the usage of description logic to capture 
 knowledge. One such choice is the Web Ontology Language (OWL) that is base
 d on description logic. Many tools were designed around this principle and
  are still widely being used to model and explore ontologies. However\, no
 t all users find description logics to be intuitive\, at least not without
  an extensive background in formal logics. Due to this\, researchers have 
 tried to explore other ways that will enable such users to model ontologie
 s intuitively. This led researchers to explore a rule-based paradigm. For 
 many users this approach was found to be a more natural and intuitive way 
 of representing knowledge. Hence\, Semantic Web Rule Language (SWRL) becam
 e an extremely popular choice among researchers and naive users. However\,
  one major problem with SWRL is that machines cannot readily process it. T
 herefore\, researchers at Data Semantics Laboratory (DaSe Lab) created an 
 interactive plugin\, called ROWLTab\, that efficiently converts rules into
  OWL axioms. This plugin allows a user to create ontologies using SWRL syn
 tax and convert it into OWL axioms. However\, the tool does not support tr
 anslation of rules that contains a disjunction and existential quantifiers
  in the consequent.In this paper we will discuss the modifications that we
 re successfully made to the existing plugin to support the translation of 
 right-hand existential and disjunction rules. We posit that this modificat
 ion gives the user the ability to model more realistic and complex ontolog
 ies. Lastly\, our evaluation shows that the tool can add 89% of the rules 
 that contains an existential quantifier and 65% of the rules that contains
  a disjunction. We also discuss why we were unable to insert the remaining
  rules more in detail.
