  1. Progress on Rule based matchmaker+alignemnt tool CERTH/ITI Votis Konstantinos

  2. Achievements • Ontology on-line browsing and downloading • Ontology Alignment tool • API for the communication of the MatchMaker with the ontology • MatchMaker - OpenRules support • Integration of the CLOUD4All MatchMaker with the GPII framework

  3. Ontology on-line browsing & downloading

  4. Ontology on-line browsing

  5. Ontology Alignment tool– Add a new solution –

  6. Ontology Alignment tool– Return matching ontology concepts –

  7. Ontology Alignment tool– Set the value of default properties –

  8. Ontology Alignment tool– Add new settings & align them –

  9. Ontology Alignment tool– The new solution has been added to the ontology –

  10. API for the communication of the MatchMaker with the ontology • Functions for getting the instances of every class contained in the ontology • Functions for getting the instances that meet specific criteria • e.g., get all the screen readers running on Linux (in general) or get all the screen readers running on Linux Debian 6 • The implementation was based on the Apache Jena framework

  11. API for the communication of the MatchMaker with the ontology (2) • Example: • //------- • //DEVICES • //------- • //get DTVDevices • ArrayList<Device> allInstances_DTVDevice = getInstances(DTVDevices_ID); • if(printDebugInfo) • { • for(int i=0; i<allInstances_DTVDevice.size(); i++) • System.out.println(allInstances_DTVDevice.get(i).toString()); • }

  12. CLOUD4All MatchMaker – OpenRules support

  13. CLOUD4All MatchMaker – Integration with the GPII framework • The GPII framework is based on Javascript • The CLOUD4All rule-based MatchMaker is based on Java • The Google Web Toolkit (GWT) has been used to enable the use of the CLOUD4All MatchMaker through Javascript • Thus, the CLOUD4All rule-based MatchMaker can be integrated into the GPII framework

  14. GPII - The “Flat” MatchMaker • Simplest possible algorithm • Index into the “skeleton solution input image” with all of the leaves derived from the user’s profile • Pick every solution for which there is an exact match

  15. GPII MatchMaker - Some useful MatchMaker Primitives • Compute the Input Image of a solution: • Step 1: convert to leaf representation with matchMaker.computeLeavesFromSolution { "type": "gpii.integrationTesting.mockSettingsHandler", "capabilities": ["display.screenEnhancement"], "capabilitiesTransformations": { "mag-factor": "display.screenEnhancement.magnification", "show-cross-hairs": "display.screenEnhancement.showCrosshairs", … [ "display.screenEnhancement.magnification", "display.screenEnhancement.showCrosshairs", "display.screenEnhancement.tracking", "display.screenEnhancement" ];

  16. GPII MatchMaker - Input Image Computation [ "display.screenEnhancement.magnification", "display.screenEnhancement.showCrosshairs", "display.screenEnhancement.tracking", "display.screenEnhancement" ]; • Step 2: Convert to “skeleton model” using matchMaker.pathsToSkeleton var magnifierSkeleton = { display: { screenEnhancement: { magnification: {}, showCrosshairs: {}, tracking: {} } } };

  17. GPII MatchMaker User – solution matching var sammyProfile = { "display": { "screenEnhancement": { "fontSize": 24, "foregroundColor": "white", "backgroundColor": "black", "fontFace": { "fontName": ["Comic Sans"], "genericFontFace": "sans serif" }, "magnification": 2.0, "tracking": "mouse", "invertImages": true, "-provisional-showCrosshairs": true } } }; var magnifierSkeleton = { display: { screenEnhancement: { magnification: {}, showCrosshairs: {}, tracking: {} } } };

  18. GPII MatchMaker- Solution/User profiles 18

  19. GPII – MatchMaker results

  20. CLOUD4All rule-based MatchMaker within the GPII framework User Profile 1 Goal: If the user uses a screen reader, find the suitable screen reader according to the defined rules. User Profile 2 User Profile 3

  21. Take into account the defined rules • If the user uses a screen reader • Get system’s time • Return the screen reader(s) that run(s) on the platform used in the current time

  22. CLOUD4All rule-based MatchMaker within the GPII framework
