STAR Webinars Ontology driven diagram generator for health simulation models Andrew Sutcliffe

NET Meeting - Montreal2 How diagrams are made?  Most often a manual process: time consuming error-prone semantics of the model can be unclear representations often inconsistent output is static (image, PPT) manual update required when the models change sim model diagram

NET Meeting - Montreal3 How diagrams are made?  Automated tools are available support established graphical formalisms, e.g. UML take care of updating diagrams upon model change restricted to specific simulation modeling toolkits output is still static sim model diagram

NET Meeting - Montreal4 Desired features  Clearly defined semantics what is the meaning of the node shapes, colors, arrow types?  Consistent graphical representation  Support for multiple representations causal view, person flow, event sequencing…  Interactive diagrams as output nesting, hierarchical viewing displaying additional info on demand  Less work to make diagrams

NET Meeting - Montreal5 Proposed solution sim model diagram ontology

NET Meeting - Montreal6 Proposed solution  Model semantics defined in the ontology clear relationships consistent encoding of different models  Automatic generation of diagrams consistent graphical representation multiple representations for the same model support for multiple output formats  Less work to make diagrams? encode once in the ontology and get many different diagrams in a consistent format

NET Meeting - Montreal7 Scope of current work  2 model examples encoded in a simplified ontology variables, dependencies, data sources for state transitions, variable clustering  Focus on one graphical representation dependency graph  Output format static images interactive web pages

NET Meeting - Montreal8 Future work  Incorporating more relationships from the ontology state transition functions temporal dynamics  Support for other diagram types event graphs person-flow …  Animated smooth transitions between views  Suggestions?
