  • PhD: Semantic Modelling of Virtual Patient

    1. 1. Using Semantic Web technology to model Virtual Patients
    2. 2. Semantic what ? <ul><li>Semantic = that has meaning </li></ul>Asking question about stuff (queries) Getting Answers Connected data
    3. 3. How it works: Resource Description Framework <ul><li>RDF describes resources (stuff) using triples : <Object, predicate, Subject> </li></ul>RDF Document says things about stuff Object Subject predicate
    4. 4. How it works: Resource Description Framework <ul><li>Simple Triple </li></ul>JR eLearning Team worksWith
    5. 5. How it works: Resource Description Framework <ul><li>Linking several triples together </li></ul>FrenchMan JR Is-a eLearning Team worksWith likesToWatch Heroes SciFi shows Lost FlashForward Is-a Is-a Is-a
    6. 6. Are we really talking about virtual patients here ?
    7. 7. Remember ? Asking question about stuff Getting Answers Connected data
    8. 8. Asking questions to our patient Asking question to our virtual patient Virtual Patient description In RDF Virtual Patient ontology Getting Answers
    9. 9. What’s that now, “ontology” ? <ul><li>Classes / Hierarchy of objects (resources) </li></ul><ul><li>Rules about objects : </li></ul><ul><ul><li>what their characteristics (properties) are, </li></ul></ul><ul><ul><li>How they connect together. </li></ul></ul>
    10. 10. Virtual Cases are interactive scenarios
    11. 11. Virtual Patients can answer questions <ul><li>The program knows about: </li></ul><ul><ul><li>Symptoms : what type, where they are located, the intensity, duration, etc. </li></ul></ul>
    12. 12. Virtual Patients can answer questions <ul><li>The program knows about: </li></ul><ul><ul><li>Medical history : pre-existing conditions, surgery undertaken in the past, etc. </li></ul></ul>
    13. 13. Virtual Patients can answer questions <ul><li>The program knows about: </li></ul><ul><ul><li>Drug history : which drug, how much, for how long </li></ul></ul>
    14. 14. Virtual Patients can answer questions <ul><li>The program knows about: </li></ul><ul><ul><li>Family/Social history : profession, relatives, relationships, etc. </li></ul></ul>
    15. 15. Students can perform actions on Virtual Patients <ul><li>Actions have consequences, and can bring the student to new events </li></ul><ul><li>Actions can reveal information (images, sound, new symptoms, etc.) </li></ul>Examinations Diagnosis Referral Treatment
