1 Mayo LexWiki: A Prototype of Collaborative Platform for Terminology/Ontology Content Development Guoqian Jiang, Ph.D. Division of Biomedical Informatics, Mayo Clinic College of Medicine. NCBO DevCon 2007 (Stanford) December 13, 2007

2 Outline Why Semantic Wikis? LexWiki machine prototype –LexWiki Editor –LexWiki Protégé Tab LexWiki Features LexWiki/Protégé Interface Future vision

3 Why Semantic Wiki? The infrastructure and culture of the semantic wiki is being considered as a promising workbench for collaborative ontology engineering. –Easy to learn tool –Open content development platform –Change history management –Formal output rendering (RDF export) –…

4 Semantic Annotations in SMW Attribute Annotation Relation Annotation

5 LexWiki Machine: A Collaboration Platform Wiki Core Semantic Wiki Semantic Forms MySQL LexBIG Export/Load Domain Experts Protégé Authoring Change sets Detection Templates LexWiki Editor LexWiki Tab

6 LexWiki Use Cases LexWiki ICD10+ –A WHO project –To realize collaborative ICD11 editing process BiomedGT –A NCI project –To realize collaborative NCI Thesaurus development process

7 LexWiki Features Browsing support –Hierarchical View –Data elements Basic data (Lexical) Concept Property Association (Relation) –Association Graph Authoring support –Workflow for Proposals (LexWiki Editor) Change proposal New concept proposal –Workflow for change set detection RDF output from LexWiki Annotation Ontology Mapping

19 Authoring Support in Collaborative Protégé Instances of Changes

20 Summary We have a dream: the emergence of a semantic web We have a problem: the creation of complete and well-defined ontologies We have a solution: to create these ontologies with collaborative ontology-editing tools We have a problem: we do not have such tools available We have a partial tested solution: LexWiki prototype
