  1. KMi-SMI collaboration Wenjin Lu and Enrico Motta Knowledge Media Institute Monica Crubézy Stanford Medical Informatics

  2. Goals • Customizing Protégé editor for use with OCML (Protégé-OCML) • Evaluating Protégé suitability • Translating classification library into Protégé-OCML • Validating classification library • Evaluating UPML • Revising Specification for Internet Reasoning Service

  3. 1. The Protégé-UPML editor for OCML • Modeling of OCML meta ontology in Protégé • i.e., classes, relations, functions, axioms, etc... • Inclusion of OCML meta ontology in Protégé-UPML editor • i.e., defining the appropriate KA forms for the basic OCML constructs • Extension of UPML concepts for OCML, with reference to OCML meta ontology • e.g., formula -> OCML-formula

  4. subclass-of link instance-of link OCML meta ontology in Protégé By the way, this is the output of a new plugin for Protégé, that creates a graph out of a KB, with different visualization options

  5. Each OCML construct is an instance of :OCML-CLASS Template slots define own OCML fields for all classes

  6. OCML in Protégé-UPML editor • Inclusion of OCML meta ontology in UPML domain modelling meta-ontology • Extension of UPML concepts for OCML (“UPML-OCML concepts”) • Formula < OCML-Formula • formula -> ocml-kappa-expression, ocml-relation-mapping • Program < OCML-Program • program -> ocml-lambda-expression, :OCML-PROCEDURE • Signature Element < OCML-Element • ocml-type -> :OCML-CLASS, :OCML-RELATION, :OCML-FUNCTION • Signature < OCML-Signature • signature-elements -> (OCML-Element)

  7. UPML core ontology is extended for OCML

  8. 2. The Classification library in UPML Classification Library Optimal classification @ Heuristic classifier PSM Refiner Task Refiner PSM-Task Bridge (Optimal) Classification Heuristic classifier Task PSM Abtractor, Refiner Observable, Solution Ontology Refiner Ontologies Task-Domain Bridge PSM-Domain Bridge Color “green”, Sugar-level Optimal classification @ Apples Heuristic classifier @ Apples Domain Refiner Solution = Apple class Abstractor = Sugar-abstractor Domain Model Apples

  9. The Classification library in Protégé-UPML • Classification ontologies modeled in Protégé-OCML • Classification task, heuristic classification method, apples domain, apples @ heuristic classification application • Modeled as separate ontologies in Protégé-OCML (ie, a hierarchy of classes that are instances of OCML primitives) • Included along with UPML-OCML (UPML extended for OCML) • UPML-OCML concepts instantiated with elements of the included classification ontologies • UPML concepts instantiated with classification tasks, PSMs, knowledge roles, etc.

  10. Classification ontologies in Protégé-OCML OCML-BASE included-in included-in CLASSIFICATION-TASK APPLE-DOMAIN included-in HEURISTIC-CLASSIFICATION-METHOD included-in included-in APPLE-HEURISTIC-CLASSIFICATION-APPLICATION

  11. Each concept is an instance of :OCML-CLASS Own slots contain OCML definition of the class

  12. Classification Library instance

  13. Classification Task instance

  14. Task: Classification (ontology signature)

  15. Task: Classification (competence)

  16. Heuristic optimal solution classifier PSM

  17. Heuristic optimal solution classifier PSM (Signature and Competence)

  18. Heuristic optimal solution classifier PSM (Operational description)

  19. Classification-task @ apples-domain bridge 4 mapping axioms define the bridge

  20. Classification-task @ apples-domain bridge (mapping axiom for observable)

  21. Conclusions of the experiment • Customization of Protégé-UPML for OCML • 2-step process: OCML in Protégé + extension of UPML for OCML • Reasonably easy to do! • Classification library in UPML • Fits nicely, except: • Knowledge roles (case-indep. data) at the task & complex PSM level • Task, PSMs, etc. are classes in OCML, not instances as in UPML • Needs the implementation of a connection to OCML interpreter

  22. 3. Internet Reasoning Service
