Basic Science Education is Changing • From ‘know what’ to ‘know how’ • From linear didactics to matrix knowledgebases • From objects to connections - knowledge networks - nodes and vertices - both important • From specifics to abstractions - structure, pattern, models, metadata • From abstractions to specifics - instantiation, service, mashup, hybrids • The function of knowledge, its creation, acquisition and representation - all in flux • We need better understanding of this changing ecosystem
The Environment is Changing • Ambient use of technology • Educational informatics underpinning it all • Monolithic ‘do-it-all’ systems still predominate but SOAs are growing: • Interoperability: ability of two or more systems to exchange data meaningfully • Integration: ability of two or more systems to exchange services meaningfully • Based on standards and specs - MedBiquitous, eFramework • Experiments in discrete knowledge services …
Experiment: Knowledge Application Markup Languages (KAMLs) • Simple • Discrete topic area • Can represent: • Content • Geography • Properties • Dimensions • Weight • Tissue • Functions • Interactions • Dependencies
SkelML <!xml> <skelml> <bones> <bone> <name>ulna</name> <notes>the word ulna is a derivation of the Greek word for elbow, parallel with the radius it is the longer of the two bones, </notes> <keywords>arm,forearm</keywords> <articulations> <articulation> <bone>radius</bone> <location1>lesser sigmoid cavity</location1> <location2>styloid process</location2> </articulation> <articulation> <bone>humerus</bone> <location1>greater sigmoid cavity</location1> </articulation> </articulations> </bone> </bones> </skelml>
Issues • 3D properties difficult to model in XML without a 3D model - e.g. attachments, joints • Normal variations in human anatomy - cf normal values • Variations of pathology and abnormality • Age/developmental issues • Semantic or simply unique IDs • Whether to have a single common model for all systems or separate per system models
Others • Nerves • Muscles • Organs • Body systems • Landmarks • Drugs • Pathologies - ICD-9 • Diagnostic models • Therapeutic models • Roles • Processes • Services
Joining them together … • Multi-dimensional matrices • Tightly coupled: • cross referenced IDs - Xpath, Xquery, Xpointer • IDs must match across models • Loosely coupled: • cross referenced semantic matching • Descriptors must match (probabilistically) across models • Instantiation: • Service-Oriented Clinical Knowledgebases (SOCKs) with high levels of abstraction • Rich semantic searching • Edge services
HSVO Edge Services • HSVO: NOSM, McGill, CRC, NRC, Stanford, IDEAL,IiL • CANARIE funding - NEP - UCLPs • Platform Services – IaaS (Infrastructure as a Service) • CCaaS (Collaboration Control as a Service) • Edge devices and services: • Mannequin • Virtual patient • Physiome • GIS • Evidence • 3D models • Common query and exchange (?standards-based) • Using SkelML, NerveML, MuscML, OrganML …
HSVO Use Cases Use Case 1: Simulated Human Aggregate Patient Environment Students working with a virtual patient, data moves to and from mannequins and physionomic models, query services against knowledge and evidence Use Case 2: Virtual Dissection Room Students working with a lightfield array, communicating and collaborating, overlaying 2D and 3D images and models, bookmarking and clipping for viewing and sharing
Experiments Educational experiments: Completeness and representation Utility and efficacy Fluidity of knowledge access and manipulation Technical experiments: Designs, models and frameworks for SOCKs Repositioning knowledge services in a ubiquitous environment Middleware and service models
KAMLs and SOCKs Simple, granular, single-subject Knowledgebase research Different levels and forms of integration Enabling other R&D Scholarship and engineering Watch this space …
