Sustainable tools, advanced technology, capacity building: ways to bridge the rural digital divide APAN workshop AG-WG sessionMargherita.Sini@fao.org Bangkok, January 2005
Outline • The AGRIS network and tools • The Food, Nutrition and Agriculture ontology-based portal • The FAO Information Management Resource Kit (IMARK)
The AGRIS network • Collaborative network of institutions (subject and geographical distributed). • Aims: collection, processing and dissemination of agricultural information. • Based on common standards and tools. • International initiative(from 1975, formally 241 participating centres). • Input centres contribute: • in a centralized way (data to FAO); • act as focal points for a more decentralized system (60 centres have their own website, publishing their bibliographical databases on the web).
The tools: WebAGRIS • WebAGRIS is a complete, multilingual Web-based system for data input, processing and dissemination (through the Internet or CD-Rom), of agricultural bibliographic information. • WebAGRIS also allows for referencing to documents in electronic format. • It is based on common standards of data input and dissemination formats (XML, HTML, ISO), as well as subject categorization schema and thesauri, i.e. AGROVOC.
WebAGRIS (cont.) • WebAGRIS can be used either as: • a local application or • in a joint collection of information (through exporting, harvesting data, etc.). • Each AGRIS network participating center can choose to host a Web site for inputting, searching and/or sending data to the central AGRIS database for publishing on CD-Rom. • WebAGRIS improvesaccessibility of informationgenerally, through theuse of multi-database ormultihost searching and harvesting.
Other resources • Multilingual Agricultural Thesaurus • AGRIS/CARIS Classification Scheme

What it is? • A web site to realize an ontology-based navigation of bibliographic data sets (the Food, Nutrition and Agriculture Journal). • The system uses a simple knowledge model to guide the user's search and browse experience: • browse by keywords, categories, authors, etc. • traverse resources and properties through the ontological relationships connecting them.
The bibliographical metadata ontology FAOBIB DOCREP Merge + Transform • The ontology is composed of: • concepts • relationships between concepts • instances
What is possible to do? • Easy navigation of the objects by following the semantic links • Multilingual concept resolution
What is possible to do? • Get suggestions for the navigation(e.g. synonyms):
What is possible to do? • Improve browsing: • e.g. continent / regions / countries • e.g. link Agris/Caris categories with keywords • Perform some inference: • get the authors associated with specific keywords or vice versa (e.g. “what an author wrote about between two years”, “who wrote about famine in 1999”, etc.) • get the co-authors • show articles with a related set of keywords
What is possible to do? • Guided query formulation • Improve searching: • concept identification through natural language processing: spell checking, parsing (e.g. “Dietary guidelines for human nutrition” or “Anaemia in children”)
