6. OWL: Web Ontology Language (RDF + Reasoning) from: Ian Horrocks, OWL 2: The Next Generation

7. Saturation-based Technique (basics) Example:

8. Ontology vs. Data-Model Ontology provides a comprehensive hierarchical view of a domain as opposed to a flat and partial representation of a data-model Computer Skill Single OntologyMultiple Data models Person Person Name First Name Last Name PersonSkill PersonName NetworkSkillProgrammingSkill Is-a Bearer-of Skill Last Name First Name Skill Person NameComputer Skill Programming Skill Network Skill

9. Ontology annotates Data Model Source database Db1, with tables Db1.Person and Db1.Skill, containing person data and data pertaining to skills of different kinds, respectively. Source database Db2.Person, containing data about IT personnel and their skills: Source database Db3.ProgrSkill, containing data about programmers’ skills: PersonIDSkillID 111222 SkillIDNameDescription 222JavaProgramming IDSkillDescr 333SQL EmplIDSkillName 444Java

17. BFO: The Very Top continuant independent continuant dependent continuant quality occurrent temperature 17

18. independent continuant dependent continuant quality temperature types instances organism John John’s temperature 18

19. independent continuant dependent continuant quality temperature types instances organism John John’s temperature 19

20. independent continuant dependent continuant quality temperature organism John John’s temperature occurrent process course of temperature changes John’s temperature history 20

21. independent continuant dependent continuant quality temperature organism John John’s temperature occurrent process life of an organism John’s life 21

22. BFO: The Very Top continuant occurrent independent continuant dependent continuant qualitydisposition 22

23. Disposition - of a glass vase, to shatter if dropped - of a human, to eat - of a banana, to ripen - of John, to anaphylactic shock 23

24. peanut allergy peanut allergy disorder = mast cells and basophils with peanut allergen-specific IgE bound to their membranes peanut allergy disease: IgE-mediated hypersensitivity to peanut allergen(s) 24

25. independent continuant dependent continuant disposition disease disorder John’s IgE-mediated allergic disorder John’s allergic disease occurrent process course of disease course of John’s peanut allergy 25
