How it works

Searching

To search AGRIS, simply enter a keyword related to the topic you are looking for in the Search box.

If you enter more than one keyword, the system will – by default – use the Boolean operator OR, retrieving first the records that contain all the keywords and subsequently the ones that contain only some of the given keywords.

To create more complex queries by hand – including other Boolean operators –  please visit the AGRIS Search Help page.

The search result will be displayed on one page with on the left side the bibliographic data and on the right the linked resources & an advanced search area.

To refine your search, you may start with clicking on the elements you find inside the advanced search area:  AGROVOC terms, names of countries and types of documents. The elements available in these boxes are the ones that are most related to the record set as a whole.

To narrow your search down even further, click on “Get Classical view”. The system will take you to a traditional view of the bibliographic data. This view offers you the possibility to execute an advanced search by bibliographic record field and to filter by country of data provider, language, full text etc.

 

… for bibliographic data

On the first result page, the ten most relevant bibliographic records are displayed on the left side of the screen, with the possibility to browse the entire result set. Initially only the author, title and abstract are displayed, but when you click on a title the full record is expanded.

Click on “Get Classical view” at the top of the record list to:
Access a traditional view of the bibliographic data.
Execute an advanced search restricted to bibliographic data.
Export single or the first 250 records in one of the following formats: AGRIS AP - EndNote TXT - EndNote XML - RDF XML - HTML - TXT. 


... for web resources enriching the AGRIS data

When you click on a title, the system will take you to the mash-up page that displays the full AGRIS bibliographic record together with its related Web resources. Currently AGRIS contains more than 7 million mash-up pages. All these pages are also indexed by Google and are thus directly accessible through a Google search.
 


What does a mash-up page contain?

Bibliographic information

AGRIS bibliographic records contain rich metadata and are largely indexed by AGROVOC, FAO’s multilingual agricultural thesaurus. They cover publications in the area of agriculture, forestry, animal husbandry, aquatic sciences, fisheries, human nutrition and extension. These publications vary from journal articles, monographs and chapters of books to grey literature, including unpublished scientific and technical reports, theses, dissertations and conference papers. For the majority of the AGRIS records, the full text is made available through the use of a Google gadget.

Linked web resources

Down below you will find a list of the data resources that have been 1) aligned with the AGROVOC thesaurus, and 2) linked to the AGRIS records (all indexed with AGROVOC). This way AGRIS is able to extract information from these resources and enrich the AGRIS data.

DBpedia: A community effort to extract structured information from Wikipedia and to make this information available on the web.
AGRIS extracts from DBPedia the definitions of concepts. It also provides you with the possibility to directly modify the information in Wikipedia.

World Bank: An international financial institution that provides loans to developing countries for capital programs. The World Bank Indicators APIs let you programmatically access more than 3,000 indicators and query the data in several ways, using parameters to specify your request. The Indicators give a lot of details about countries: name, region, coordinates, capital, income level, lending type, total population, etc.
AGRIS uses the World Bank APIs to retrieve widgets (maps, charts).

Google Custom Search API enables you to search a website or a collection of websites, create a search engine tailored to specific needs and interests, and present the results in your website.
AGRIS queries Google Custom Search APIs to retrieve the full texts of the AGRIS records.

Nature OpenSearch provides an open, bibliographic search service for content hosted on nature.com, comprising around half a million news and research articles and citations. The API is accessible both through a Sparql endpoint as a REST Web service (AGRIS’s choice).
AGRIS queries Nature’s API to retrieve articles and publications.

FAO Geopolitical Ontology – Country profiles: An ontology that contains country statistics, official country names and codes.
AGRIS extracts from this ontology information about countries.

Global Biodiversity Information Facility  works to mobilize data and to improve search mechanisms, data and metadata standards, web services, and the other components of an Internet-based information infrastructure for biodiversity.
AGRIS queries the GBIF repository to obtain the KML of the Distribution Map for Species.

International Food Policy Research Institute (IFPRI): An international agricultural research center that aims to improve the understanding of national agricultural and food policies to promote the adoption of innovations in agricultural technology.
AGRIS queries the IFPRI Sparql endpoint to retrieve the Global Hunger Indicator and Children Mortality Rate by country.

FAO Fisheries and Aquaculture fact sheets API allows you to download statistical graphs about fish species.
AGRIS queries the APIs to obtain the Aquatic species capture and aquaculture production graphs.

Bioversity International contains 3200 unique original field report documents, recording information about more than 200,000 landrace and crop wild relative samples collected all over the world for almost forty years.
AGRIS extracts information from the Crop Collecting Missions.


How are the mash-up pages created?

The Linked Open Data Methodology was used to link the AGRIS bibliographic datasets –  Records, Serials, Centers –  to related datasets on the web.

  1. The AGRIS datasets were converted to RDF creating some 200 million triples. To see how this was done, take a look at the set of properties that were used to build the AGRIS Records RDF dataset.
  2. AGROVOC was aligned to other thesauri.
  3. Sparql endpoints, web services and APIs were discovered.
  4. AGRIS RDF was interlinked –  using AGROVOC LOD as a backbone –  to external datasets.

Final result: The current web mash-up application through which you can query the AGRIS-RDF content and its linked resources.

Where can you access the AGRIS Sparql points?

AGRIS RDF is stored at MIMOS in Malaysia which uses Allegrograph to manage the triples. To access the Sparql endpoints of the AGRIS datasets, please see the links down below.

Then, the VoID file “VoID.ttl” gives you the description of the linked datasets, while the Data Hub website gives you more information about AGRIS LOD and the possibility to search for data and published datasets.
