The objective of this presentation is to give an introduction to the new AGRIS website (that was released on the 2nd of December 2013) and its functions. The new website merges the AGRIS system with OpenAGRIS and provides a simple access point to search bibliographic data in the AGRIS data base.

  • A brief introduction to AGRIS and some definitionsA very brief description of the processes that brought our team to implement the Linked Open data technologiesAn outline of how data is generated, validated, ingested, triplified and publishedInteroperability facilitates data exchange
  • Maize in DBPedia is a plant, in Agrovoc is a product, so closeMatch
  • Transcript

    • 1. AGRIS – exploiting bibliographic records to create rich Linked Open Data pages AIMS Webinar Fabrizio Celli Johannes Keizer Presentations by AIMS is licensed under a Creative Commons Attribution-NonCommercialShareAlike 3.0 Unported License.
    • 2. Outline  AGRIS network and dataflow  Data Consumption • Centralization • Interlinking  Provenance http://agris.fao.org 2
    • 3. AGRIS  The AGRIS database is a collection of more than 7.7 million bibliographic records in the agricultural domain  They are enhanced by the AGROVOC thesaurus, which is extensively used by cataloguers to enrich data indexing in agricultural information systems  AGRIS is an RDF-aware system, a mashup application that allows users to query the AGRIS-RDF content, interlinking all records to external sources of information  7 million bibliographic records become 7 million mashup pages! http://agris.fao.org
    • 4. AGRIS data consumption  Centralization: bibliographic references in the AGRIS domain (agriculture, forestry, animal husbandry, aquatic sciences and fisheries, and human nutrition)  Interlinking: other kinds of information related to the AGRIS domain (statistics, maps, country profiles, etc.) http://agris.fao.org
    • 5. Data consuming  AGRIS consumes metadata provided by the community and publishes it as open data  The metadata is captured either by pulling data through harvesting from clients (e.g. aggregators, institutional repositories, using protocols such as OAI-PMH)  or by pushing data to AGRIS from clients (e.g. national libraries or journal publishers) http://agris.fao.org
    • 6. Interoperability -Accept any input format! http://agris.fao.org
    • 7. AGRIS data flow http://agris.fao.org
    • 8. Centralization: Data processing  Metadata are randomly manually checked to look for inconsistencies or recurring semantic errors  Input format is mapped to AGRIS RDF  Metadata are converted to AGRIS RDF, running the AgroTagger when Agrovoc keywords are not available  Before adding metadata to the triplestore and indexing them in the Solr index, duplicates are detected and managed, as the same record may be indexed in multiple collections or be duplicated in the same repository http://agris.fao.org
    • 9. AgroTagger Maui is named after the Polynesian mythological hero and demi-god, which would transform himself into different kinds of birds to perform many of his exploits. http://agris.fao.org Not yet implemented
    • 10. RDF-ization Choose of vocabularies and mapping! bibo:Article bibo:abstract bibo:doi bibo:isbn bibo:presentedAt -> bibo:Conference -> dct:title bibo:uri dct:alternative dct:creator -> foaf:organization -> foaf:name dct:creator -> foaf:Person -> foaf:name dct:dateSubmitted dct:description dct:extent dct:identifier dct:language http://agris.fao.org dct:isPartOf dct:issued dct:publisher -> foaf:Organization -> foaf:name dct:source dct:subject dct:title dct:type dct:rights
    • 11. RDF/XML snapshot http://agris.fao.org
    • 12. Provenance  Each AGRIS record has an identifier (ARN), which has a predefined structure and contains information on the data source together with the bibliographic record’s year of creation  “IT 2008 0 00091” refers to a record created in 2008 from a specific AGRIS data provider in Italy, whose progressive number is 91  Data providers information are stored in the CIARD RING and triplified in the AGRIS centers dataset (each data provider has its own unique URI) http://agris.fao.org
    • 13. Storage system  AGRIS RDF is stored in Malaysia, at MIMOS (http://www.mimos.my/ )  Triples are managed by Allegrograph triplestore (http://www.franz.com/agraph/allegrograph/)  A 90GB machine is dedicated to the triplestore. Some month ago we used a 32 GB machine, but Allegrograph once a month (at least) went down (pending processes, memory problems)  We did tests with OWLIM and we could move to this triplestore, or find another kind of solution http://agris.fao.org
    • 14. Interlinking  Agrovoc is the backbone  Align Agrovoc to other thesauri (skos:exactMatch, skos:closeMatch)  Discover Sparql endpoints  Discover Webservices and APIs  Write the code and interlink! http://agris.fao.org
    • 15. The IFPRI case A user queries the system AGRIS record with Agrovoc keywords At least one Agrovoc keyword is a Country name The system queries IFPRI sparql endpoint (http://data.ifpri.org/sparql/ ) to retrieve the global hunger index (GHI) and the child mortality rate related to the Country http://agris.fao.org
    • 16. Some numbers (02/12/2013)  7,636,069 bibliographic records  187,238,716 triples in the AGRIS records dataset http://202.45.142.113:10035/repositories/agris  372,462 triples in the AGRIS serials dataset http://202.45.142.113:10035/repositories/jad  11,414 triples in the AGRIS centers dataset http://202.45.142.113:10035/repositories/centers http://agris.fao.org
