From flat world to semantic world ● We are used to use flat representaion of the reality ● Using books till recently ● Using informatics and database like Excell, Access or SQL ● Needs in knowledge management and classification fields are growing and multiaxial representation of the reality is needed

New information technology available Out of the closed world of databases The information and the information about information DATA + METADATA Everything can be identified by URIs A URI is a formal representation of an unit of information

New information technology tools available XML Customized tags, like: Marc +RDF Relations, in triples, like: (Marc) (is_member_of) (WICC) +Ontologies Hierarchies of concepts, like drug -> late effect -> tiredness -> patient +Inference rules Like: If (person) (has) (disease), then (person) (looks_for) (doctor) =Semantic Web!

The Semantic cake

Linking data on the web THE LINKED DATA WORLD

Exploring semantic world Sharing knowledge with computer scientist at CETIC ● « Fair » exchange : ● Knowledge and tools in classification world Versus ● Knowledge and tools in semantic world by – --> lecture & exercises – --> LOCAS +

Exploring the link between Locas codes 5000 usual words of GP/FM to CISP-2 3BT links terms, each with a unique ID (called IBUI) to a French label, a Dutch label, ICPC and ICD code Two terminologies Two classification : ICPC-2 & ICD- 10

LOCAS + : Exploring relations with semantic tools All items are transformed in URI and edited on the net Query by a special semantic query tool called SPRQL

Exploring the tool 4 classes

Exploring the tool Properties of the classe cisp2#dataset

Exploring the tool Properties of the classe icd10#dataset Properties of the classe locas2#dataset

Exploring the tool Properties of the classe threebt#dataset

Exploring Locas plus semantic browser ●
