  1. Comparing ontological concepts based on recursive traversing of the ontology structure Anton Andrejko

  2. Basic terms • Comparing domain ontology concepts • Maintenance and redundancy check on ontology repositories, prevention of presentation • Concepts from the same ontology only • Different ontologies  ontology mapping/matching problem • Concept is represented as ontology class instance • Attributes with assigned values • Data type and object type attributes

  3. Innovation • Involvement of the user • User preferences to get personalized similarity  weights • User evaluation to deduce characteristics • Similarity • The use of different strategies for evaluation • Each strategy contributes to the total similarity

  4. Recursive evaluation 1. ID = FirstInstance 2. get all attributes where ID stands for Subject 3. for each attribute 4. pick a attribute from SecondInstance 5. if attribute is data type 6. use string strategies to evaluate similarity 7. if attribute is object type 8. use class based similarity strategies to evaluate similarity 9. ID = Object 10. go to line 2 11. count partial similarity 12. count total similarity
