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) –…

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
