  3. KYOTO (ICT-211423) Overview • Title: Knowledge 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: • Open and free platform for knowledge sharing across languages and cultures • Wiki environment that allows people in the field to maintain their knowledge and agree on meaning without knowledge engineering skills • Bootstrap through open text mining & concept learning • Enables knowledge transition and information search across different target groups, transgressing linguistic, cultural and geographic boundaries. • Enables deep semantic search for facts and knowledge • URL: http://www.kyoto-project.eu/ (http://www.kyoto-project.eu/) • Duration: • March 2008 – March 2011 • Effort: • 364 person months of work. Asian Language Resources Summit, Phuket, March, 2009

  4. Consortium • Vrije Universiteit Amsterdam (Amsterdam, The Netherlands), • Consiglio Nazionale delle Ricerche (Pisa, Italy), • Berlin-Brandenburg Academy of Sciences and Humantities (Berlin, Germany), • Euskal Herriko Unibertsitatea (San Sebastian, Spain), • Academia Sinica (Tapei, Taiwan), • National Institute of Information and Communications Technology (Kyoto, Japan), • Irion Technologies (Delft, The Netherlands), • Synthema (Rome, Italy), • European Centre for Nature Conservation (Tilburg, The Netherlands), • Subcontractors: • World Wide Fund for Nature (Zeist, The Netherlands), • Masaryk University (Brno, Czech) Asian Language Resources Summit, Phuket, March, 2009

  5. KYOTO (ICT-211423) Overview • Languages: • English, Dutch, Italian, Spanish, Basque, Chinese, Japanese • Domain: • Environmental domain, BUT usable in any domain • Global: • Both European and non-European languages • Available: • Free: as open source system and data (GPL) • Future perspective: • Content standardization that supports world wide communication Asian Language Resources Summit, Phuket, March, 2009

  6. State of the artin the environment domain

  7. Baseline for environment domain • Mainly use Google, first 10 hits, no advanced options • Textual search with linguistic enhancements but no real semantic search: • polluted water…. • polluting water…. • Growing time & information pressure: • deliver actual information from diverse & dynamic sources • regional, local situations ►no general source • various subdomains ► government, legal, biology, health, industry • difficult access ► scientific publications • no time to read ► too much information and work pressure • dependent on trust: scientists ► environmentalist ►government ►general public Asian Language Resources Summit, Phuket, March, 2009

  8. High-level targets &Low-level questions • High level target (about 300 questions collected) • Are there huge negative effects with regard to ecological networks and alien invasive species? • Low level facts that support answering the high level targets: • cases of alien invasion • amount of species • causal relations associated with these (increments of) invasions • causes related to ecological networks • limit in the same time and location boundary Asian Language Resources Summit, Phuket, March, 2009

  10. Baseline retrieval results 6 persons, 30 high-level questions, Asian Language Resources Summit, Phuket, March, 2009

  11. KYOTO's Solution • Text mining: • Massive and accurate indexing of facts from vast amounts of text; • In any language/culture from scattered sources; • Again and again to detect trends and changes; • Direct relation between knowledge modeling effort and text mining • Knowledge modeling: • automatic learning of terms and concepts from text in any language; • formalization of knowledge in computer usable format -> wordnets & ontologies • Community software: • For experts in the field and not knowledge engineers • Continuous and collaborative effort: • adapt to the changing domain; • consensus in the field; • consensus across languages and cultures • Produce interoperable, formal, standardized knowledge structures; • Relate knowledge structure to expressions in languages Asian Language Resources Summit, Phuket, March, 2009

  19. Knowledge mining

  20. Knowledge mining • Concept mining (Tybots): • Extract terms and relations in a language • Map the terms to an existing wordnet • Ontologize terms to concepts and axioms • Fact mining (Kybots) • Define logical patterns • Define expression rules in a language Asian Language Resources Summit, Phuket, March, 2009

  21. What Tybots do... • Input are text documents • Linguistic processors generate KAF annotation (sequential): • morpho-syntactic analysis • semantic roles • named entities • wordnet and ontology mappings • Output are term hierarchies in TMF (generic): • structural parent relations • quantified structural and semantic relations • statistical data Asian Language Resources Summit, Phuket, March, 2009

  23. What Kybots do • Input: • KAF annotations of text: sequential & encoded by language • Conceptual frame from the ontology • Expression rules for frame to language mapping: • Wordnet in a language • Morpho-syntactic mappings rules • Output are a database of facts in FactAF (generic): • aggregated facts • inferred facts • language neutral Asian Language Resources Summit, Phuket, March, 2009

  24. Fact mining • KYBOT = Knowledge Yielding Robot • Logical expression • (instance, e1, Burn) (instance, e2, Warming) (cause, e1, e2) • (instance, s1, CO2) (instance, e1, GlobalWarming) (katalyist, s1,e1) • Expression rules per language: • [N[s1]V[e1]]S e.g. "CO2 is emitted", "fine dust blocks sun-light" • [N[s1]N[e1]N e.g. "CO2 emission", "sun-light blocking" • [[N[e1]][prep][N[s2]]NP e.g. "emission of CO2", "sun light blocking by fine dust" • Ontology * Wordnets • Capabilities: WNT -> adjectives ("explosive", "toxic"), WNT -> nouns ("explosive", "poison") • Causes: WNT -> verbs ("eat") , WNT -> nouns ("consumption") • Process: DamageProcess, ProduceProcess • Kybot compiler • kybots = logical pattern+ ontology + WN[Lx] + ER[Lx] Asian Language Resources Summit, Phuket, March, 2009

  33. Conclusions

  34. 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 repositories & fact alert: reports changes in facts on a collection of sources • Domain WORDNETS and domain ONTOLOGIES • Create the backbone for the Global Wordnet Grid Asian Language Resources Summit, Phuket, March, 2009

  35. What makes KYOTO unique? • Integrates & combines all ► knowledge engineering, language engineering, wikis, term & concept learning, fact mining from text in and across languages, & standardization • Direct relation between concept modeling and text mining ► make it worth the effort • Wikyoto community tool ► 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 communities all over the world Asian Language Resources Summit, Phuket, March, 2009

  36. What makes KYOTO unique? • Text mining and ontology learning developed for separate languages • ►KYOTO multi and cross-lingual & cultural • ►cross-lingual and cross-cultural semantic interoperability • Text mining and ontology learning is often limited to a specific domain and/or application ►KYOTO for any domain and application • Text mining and ontology learning does not relate the terms and concepts to generic language and knowledge resources ►KYOTO anchors knowledge from a community to general vocabulary and likewise to other communities Asian Language Resources Summit, Phuket, March, 2009
