15. Current Knowledge Stores
• Pharmacy Local Database
• Stores customer customer information, prescription information,
and inventory of drugs.
• Physical Prescription
• Drug information, dosage.
• Indexing System
• Locates drug information, patient history in pharmacy
• Physician’s Database
• Physician’s access to patient’s records
15

16. Knowledge Management
Portfolio
• Decision Support System (DSS)
• Provide expert knowledge to aid pharmacist’s decision.
• Electronic Publishing System
• Access to patient information using electronic means.
• Web Portal
• Provides access to tools like wikis, form, email, search, and
retrieval tools.
• Intranet
• Facilitates access to patient past prescription and records across
different pharmacies.

17. Selected Portfolio
• Decision Support System (DSS)
• Electronic-Prescription (EP or E-Prescription)
(combines with Electronic Publishing System)

29. Role of ontologies
29

30. Why Ontologies?
• Unified Healthcare System
• Ontologies can explicit conceptualize the semantics of the data
• Ontologies can make deductions and reasoning.
30

31. What do ontologies do?
• Ontology application are classified into:
• Semantic integration
• Search
• Decision Support System(DSS).
31

32. 32
Which languages?
• RDF
• RDF schema
• OWL
• Rules
• KIF
• Common Logic
• FOL
Powerful logical
languages

diseases, drug, and
instructionsFor all (x)
(If disease(x)
(exists (y) exists (z)
and ( and medicine(y)
has_medicine(x,y))
(and instruction(z)
has_instruction(x,y,z)))).

Relationship
For all(x)
(iff prescription(x)

Drug prescription error
For all(x)

( not exists (y)
(and medicine(y)

has_ message(x,w,z)).

37. 37
Benefits of Using our Ontology
• It does not have other languages or ontologies constraints
• all other semantic web languages are constriction of FOL.
• It is powerful in making deduction and reasoning
• It could make inference between different ontologies.
Horrocks et al.

Web Architecture:
Stack or Two
Towers?

38. 38
Ontology Structure
• Our ontology is using different existing ontologies and using
ontology mapping techniques to connect them to each other.
• WSMO (Web Services Modeling Ontology)
• DOPE (Drug ontology)
• Disease ontology
