  1. Ontology-based Software Engineering • Shao-yen Cheng Date

  2. Software “Engineering” • Are you calling yourself an ENGINEER? Based on what? • SE is NOT a genuine engineering discipline, yet. • Lack of fundamental principles • Strongly relies on engineering practice instead of science

  3. Software • Essential Difficulties by Frederick Brooks: • Intangibility • Complexity • Conformity • Changeability • “Software is a knowledge repository. The knowledge that is stored in software largely relates to the application domain, and not to software as an entity itself.” - Phillip G. Armour

  4. Software Engineers’ Job • Mostly, communications • Human-to-Human • Human-to-Machine • Machine-to-Machine

  5. Semiotic Triangle

  6. Conceptual Modeling • E/R Model • UML

  7. Conceptualization • C = (D, W, R) • D: a set of all elements in a domain • W: a set of all possible worlds in the domain • R: a set of conceptual relations in the domain space <D, W>

  8. Ontology • Ontology • is introduced by Aristotle, the study of being qua being • studies the essence of existence • An ontology • is a artifact developed to express the meaning of a vocabulary. • must be valid in all possible worlds of the domain. • A good ontology limits possible interpretation of a vocabulary

  9. Goals • Knowledge Sharing • Knowledge Reuse

  10. Languages • First Order Logic • OWL • Modal Logic • Higher Order Logic • Logic Programming Language • UML

  11. Application of Ontologies • Neutral Authoring • Specification • Common Access to Information • Ontology-based Search

  12. In Software Engineering Context • Analysis • Domain Ontologies • Design • Component Reuse • Implementation • Coding support • Documentation support

  13. In SE Context (cont.) • Deployment • Semantic Web Services • Maintenance • Traceability

  14. Potentials • Open Ontology • Domain Ontology Libraries • Domain Specific Languages Generation • Model Transformation • Model Driven Engineering

  15. Contribution to 577 • Build a shared knowledge base • Reduce time to learn domain knowledge • Ontology-based search on components
