Ontology in ProOptiBeef

By “ontology” here we meanformal specification of domain knowledge shared by parties involved ininformation exchange.

Ontologies are intended tohelp in expressing the resultsof the project in anunambiguous way;

be used as a component of asystem for searchinginformation in a database ofscientific articles;

be used as a component inexpert system gathering theresults of the project andrevealing them to the public.



Ontology in ProOptiBeef

OntoBeef Library

Domain: knowledge about beef, its production and consumption.

Papers: metadata knowledge about documents and contains adescription of hundreds of scientific papers on domain.

Science: description of problems, methods, data and theses.

OntoBeef Evaluation

OntoBeef Evaluation

OntoBeef ontology has been evaluated by seven domain experts.The experts has been invited to three-stage evaluation process:1 The experts have been choosing the concepts to be validated.2 They have been evaluating labels assigned to each concept.3 They have been assessing the ontological relations between concepts.


OntoBeef Evaluation Concepts choosing

OntoBeef Evaluation: First Stage

Experts have been asked to choose among all 2344 concepts thesewhich belong to their domains of interest.Concepts were displayed one by one. Each of them was represented bythe sequence of synonymous names. An expert could choose between“Yes” and “No”.


OntoBeef Evaluation Labels evaluation

OntoBeef Evaluation: Second Stage

Experts were asked to make an order in the labels assigned to eachconcept.Experts might also add a new synonymous label to the concept in anylanguage.


OntoBeef Evaluation Evaluation of the ontological relations

OntoBeef Evaluation: Third Stage

The final stage of the evaluation process was analysis of theontological relations in OntoBeef.For each concept the following information has been provided: itslabels, ancestors, children, siblings and some ontological connections.

The result of this evaluation stage was 494 received submissions.Trójczak, Trypuz (KUL, PZPBM) OntoBeef Ontology FedCSIS: Cracow 2013 11 / 21

Linked Data Philosophy

Two meanings of “Linked Data”:a method of knowledge creation and sharing,a collection of interrelated datasets on the Web.

Tim Berners-Lee provided the following set of requirements which adata should possess to be called Linked Data:1 to be available on the web;2 to be available as machine-readable structured data;3 to be coded in some of open standards from W3C (e.g. RDF) to

identify things;4 to be linked to other people’s data.

Linked Open Data (LOD) is Linked Data which is released under anopen license.



OntoBeef & LOD – statistics

OntoBeef has:

797 links with AGROVOC,

211 links with GEneral Multilingual Environmental Thesaurus(GEMET),

546 links with National Agricultural Library’s Agricultural Thesaurus(NAL),

and 119 links with STW Thesaurus for Economics.

Thesaurus component

Thesaurus component was developed within Java EE plus OWL-APIframework.It enables you to browse the ontology. Application enables alsoregistration and after log in allows reporting suggestions andcomments considering concept labels, ancestors, children and otherontological properties.In the top application bar there is LOD part, which displays LODconnections.
