Outline

• Introduction

• The AGROVOC/CS Workbench

• Future works



Introduction



FAO as a Knowledge Organization• Knowledge Exchange & Capacity Building

Division

• Teminological resources (AGROVOC, FAOTERM, Glossaries, etc.)– Avian Influenza Glossary (Avian Influenza/Pandemic

Influenza Glossary in collaboration with World Health Organization)

• Subdomain ontologies• Agricultural IM standards: http://www.fao.org/aims



The AGROVOC/CS Workbench



Background (1/2)

• AGROVOC– Used worldwide– Multilingual (online 11 languages)– Term-based (as opposed to concept based)– Limited semantics (NT, BT, RT, USE/UF)– Maintained as a relational database– Distributed in several formats (RDBMS,

TagText, ISO2709, ...)



Background (2/2)

• Draft versions available in TBX, SKOS, OWL• Access to full thesaurus through seven Web

Services

• Agricultural Ontology Service (AOS)



AGROVOC/CS Workbench: a collaborativecollaborative ontology development tool

• Support and manage the multi-language terminology work of information management specialists in the development, maintenance, and quality assurance of the CS.



AGROVOC/CS Workbench: Users

Current status

• AGROVOC/CS Workbench construction (ongoing)– CS OWL model described– Test project available– Full AGROVOC conversion procedure using

the OWL model (ongoing)– Relationships definition (in collaboration with

CNR, Italy) (ongoing)– Performance tests (ongoing)



Next steps

• Completion of the AGROVOC/CS Workbench• AGROVOC conversion and further refinement• Extensive testing on scalability, concurrent use of

the Workbench etc.• Create a network of ontology experts

– Multilingual subject experts: term editors, ontology editors, validators

– Workshops/Trainings

• NeOn



Future works and collaborations

1



The Semantic Web meets WEB 2.0: cataloguing and annotating

Web Resources (1/3)• Producing semantically rich, multilingual

knowledge repositories

• Combine social bookmarking with Ontology based bookmarking

• Composing, organizing and offering information from different knowledge repositories (distributed ontologies)



The Semantic Web meets WEB 2.0 (2/3)• Collaborative aspects

– Distribution of ontological data– Collaborative semantic annotation – Collaborative editing of ontologies

• Data Integration– Ontology Learning– Automatic discovery of ontologies (Ontology Crawling)– Linking/Merging of ontologies

• Linguistic Aspects– Identity of concepts: discovering of linguistic phenomena like

synonymy/homonymy– Linguistic Enrichment of Ontologies– Multilinguality



The Semantic Web meets WEB 2.0 (3/3)• People/Expert discovery service• Working on the case study: avian flu• Partners

– FAO– University of Rome Tor Vergata, Italy– Kasetsart University, Bangkok, Thailand– Yahoo, UK/Ireland– Elsevier, Netherlands– University of Bielefeld, Germany – ....



demos



Semantic Turkey Università Tor Vergata Roma, Italy

• Semantic Web technologies are offering standards for knowledge representation and for content exchange

• Obtain a clear separation between pure knowledge data (the WHAT) and web links (the WHERE)

• Offer innovative navigation of both the acquired information and of the pages where it has been collected

• The project has been focused on innovative solutions for browsing the web and for organizing the information which is observed during navigation



OntoLing Università Tor Vergata Roma, Italy

• Exploiting Linguistic Resources for building linguistically motivated ontologies

• Linguistic Enrichment of Ontologies– Manually– Automatically




2



Early warning systems (1/3)• Emerging infectious diseases warning system

• Use cases: Bird Flu, Rice

• Problem: today systems in many domains already exist but there is no efficient access to them. The information is scattered and not organized

• Structured information (e.g. the CS) can be used to organize unstructured information (wikis and blogs)



• Resources– FAO CS, Metadata and multilingual subject ontologies

– AGRIS data

– Department of Livestock data

• Topics– From unstructured information to structured information

– Distributed and collaborative knowledge building

– Knowledge mapping

– Topic map

– Knowledge engineering, knowledge mining, data mining

– Intelligent decision support systems (diagnosis analysis)

Early warning systems (2/3)



• Partners– Thai Ministry of Science and Technology (NECTEC)– Thai Ministry of Agriculture (Department of

Livestock)– Kasetsart University, Bangkok, Thailand– Thai Agris Center, Bangkok, Thailand– HAII, Bangkok, Thailand– FAO– Consortium of Asian countries (APEC)– .....

Early warning systems (3/3)




3



Grid Technologies in Digital Libraries (1/2)

• Combine distributed repositories through ontologies by means of the grid technology– Several institutions– Repositories of scientific data, GIS, statistical data– Domain of fisheries / aquaculture



Grid Technologies in Digital Libraries (2/2)

• Partners– FAO– Italian National Research Center (CNR), Italy– Thai National Grid Center, Kasetsart University,

Bangkok– Thai National Agris Center, Kasetsart University,

Bangkok – NECTEC, Thailand – ....
