OpenAGRIS beta (19-03-2012)

N.B. OpenAGRIS was merged to AGRIS in December 2013. Now only the AGRIS system exists.

OpenAGRIS datasources

AGRIS is one of the most important world-wide information systems in the area of the agricultural sciences, containing more than 7 million of XML bibliographic records in the agricultural sector. These bibliographic records are manually created by cataloguers and sometimes suffer of lack of information, like the full text of a document. Specifically, only 3% of the entire collection has a full text link, so the user has to search Google to find the publication. Moreover, lack of information like connections with related work and related web resources makes impossible to interlink to other sources of data. Linked Data is the way to publish structured data and to interlink with other existing datasets, in a machine readable way: to overcome the lack of information of AGRIS records, it was necessary to convert the whole repository in RDF [a language for expressing data models using statements expressed as triples (subject, predicate, and object) and publishing it on the Web] and become part of the Linked Open Data cloud. Thus, more than 190 million triples were generated and used by OpenAgris, a web application that aggregates information from different Web sources to expand the AGRIS knowledge providing much data as possible about a topic or a bibliographical resource. Using Agrovoc as backbone, OpenAgris can interlink with a lot of existing datasets (actually DBPedia, World Bank, Geopolitical Ontology, FAO fisheries dataset, AGRIS serials dataset, etc…), showing as much information as possible about a specific topic, as statistics about fish species or geographical distribution of plants. In this way, OpenAgris will be a centralized portal that will aggregate all information the Web knows about a specific topic, research area (in the agricultural sector) or bibliographic reference.

To see OpenAgris in action, you can perform a search in the AGRIS portal and then click on the related button in the display record page. As an example, you can analyze the record:

that links to the page:

As you can see, in the left frame there is the information retrieved from DBPedia and FAO country profiles (but, in general, it contains other data sources, as World Bank), in the right frame there is the information taken from the AGRIS journals dataset and from Google, in the middle there is the record and the Agrovoc keywords.

The Sparql endpoint is:

Here is an example:

Consider that authors, corporate authors, publishers and conferences haven’t been disambiguated yet, so the RDF uses blank nodes.
