KYOTO (ICT-211423) Overview • Title: Yielding Ontologies for Transition-Based Organization • Funded: • 7th Framework Program-ICT of the European Union: Intelligent Content and Semantics • Taiwan and Japan funded by national grants • Goal: • Platform for knowledge sharing across languages and cultures • Enables knowledge transition and information search across different target groups, transgressing linguistic, cultural and geographic boundaries. • Open text mining and deep semantic search • Wiki environment that allows people in the field to maintain their knowledge and agree on meaning without knowledge engineering skills • URL: http://www.kyoto-project.eu/ • Duration: • March 2008 – March 2011 • Effort: • 364 person months of work. 1st Kyoto workshop: Environmental Knowledge Transition and Exchange, February, 2-3, 2009, Artis Amsterdam

Kyoto main assets • Wiki platform (WIKYOTO) for connecting, transferring and controlling knowledge and information across people and computers • Term yielding robots (TYBOT): software that extracts terms and concepts from documents • Knowledge yielding robots (KYBOT): fact extraction software that generates a comprehensive list of facts from collection of sources • Fact alert: reports changes in facts on a collection of sources 1st Kyoto workshop: Environmental Knowledge Transition and Exchange, February, 2-3, 2009, Artis Amsterdam
What makes KYOTO unique? • Wikyoto community tool that hides technology and complex knowledge and language representation • Operated by community people and not by knowledge engineers and language technology people • Exploits massive labor force of comunities all over the world • Connects domain knowledge to generic knowledge and domain language to general language 1st Kyoto workshop: Environmental Knowledge Transition and Exchange, February, 2-3, 2009, Artis Amsterdam
Some basics • What is a wordnet? • What is an ontology • What are facts? 1st Kyoto workshop: Environmental Knowledge Transition and Exchange, February, 2-3, 2009, Artis Amsterdam
WordNet • Semantic network in which concepts are defined in terms of relations to other concepts, e.g. "car is a type of vehicle and so is a train". • Structure: • organized around the notion of synsets (sets of synonymous words, e.g. "car, automobile") • basic semantic relations between these synsets • http://www.cogsci.princeton.edu/~wn/w3wn.html • Developed at Princeton by George Miller and his team as a model of the mental lexicon. 1st Kyoto workshop: Environmental Knowledge Transition and Exchange, February, 2-3, 2009, Artis Amsterdam

Ontologies • Formal definition of concepts that a computer can use to make inferences • Uses logical representations of relations and properties of things • Can be used to connect the meanings of words across languages and different domains 1st Kyoto workshop: Environmental Knowledge Transition and Exchange, February, 2-3, 2009, Artis Amsterdam
Ontology Example • <EcoSystem rdf:ID="Living_Plant_Instance_12"> • <SUO-name rdf:datatype="http://www.w3.org/2001/XMLSchema#string" • >freshwater species</SUO-name> • </EcoSystem> • <Event rdf:ID="Living_Plant_Instance_30009"> • <rdf:type rdf:resource="#ChangeOfState"/> • <SUO-name rdf:datatype="http://www.w3.org/2001/XMLSchema#string" • >increase</SUO-name> • </Event> • <ChangeOfState rdf:ID="Living_Plant_Instance_20015"> • <SUO-name rdf:datatype="http://www.w3.org/2001/XMLSchema#string" • >double</SUO-name> • </ChangeOfState> • <Event rdf:ID="Living_Plant_Instance_30017"> • <rdf:type rdf:resource="#ChangeOfState"/> • <SUO-name rdf:datatype="http://www.w3.org/2001/XMLSchema#string" • >conversion of natural habitat to farmland</SUO-name> • </Event> 1st Kyoto workshop: Environmental Knowledge Transition and Exchange, February, 2-3, 2009, Artis Amsterdam

Concrete results of Kyoto • Domain wordnet for the environment domain • Domain ontology for the environment domain • Wikyoto to maintain the wordnet and ontology in the future in a community • Tybots to extract new terms for the domain from documents • Kybots to extract facts for the domain from documents • A database of facts that is updated on a regular basis 1st Kyoto workshop: Environmental Knowledge Transition and Exchange, February, 2-3, 2009, Artis Amsterdam
Global time schedule 1st Kyoto workshop: Environmental Knowledge Transition and Exchange, February, 2-3, 2009, Artis Amsterdam
The role of the users • Provide sources and documents • Define the questions and topics of interest • Form a community that uses the Wikyoto system to define terms and ontology • Give feedback on the Wikyoto system and the extracted terms • Extract facts and evaluate the system • Join the forum discussions on the website of Kyoto 1st Kyoto workshop: Environmental Knowledge Transition and Exchange, February, 2-3, 2009, Artis Amsterdam
Goal of this Workshop • Bridge the gap between the enviromentalist and knowledge engineer. • Discuss the requirements of the system of the future and near-future • Discuss the design and first versions of the KYOTO system and compare it with the state of the art 1st Kyoto workshop: Environmental Knowledge Transition and Exchange, February, 2-3, 2009, Artis Amsterdam
