This document discusses the evaluation of the OntoBeef ontology, which was created as part of the ProOptiBeef project to optimize beef production in Poland. The ontology covers concepts related to beef production and consumption. It was evaluated in three stages by seven domain experts: 1) experts selected relevant concepts from the 2,344 concepts in the ontology; 2) experts evaluated concept labels; 3) experts assessed ontological relations between concepts. The ontology was also linked to other related open datasets and can be used to build an ontology-driven information system and a thesaurus component to browse and provide feedback on the ontology.

5. Ontologies within ProOptiBeef
Ontology in ProOptiBeef
By “ontology” here we mean
formal specification of domain knowledge shared by parties involved in
information exchange.
Ontologies are intended to
help in expressing the results
of the project in an
unambiguous way;
be used as a component of a
system for searching
information in a database of
scientific articles;
be used as a component in
expert system gathering the
results of the project and
revealing them to the public.

Ontology in ProOptiBeef
OntoBeef Library
Domain: knowledge about beef, its production and consumption.
Papers: metadata knowledge about documents and contains a
description of hundreds of scientific papers on domain.
Science: description of problems, methods, data and theses.

8. 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.
Trójczak, Trypuz (KUL, PZPBM) OntoBeef Ontology FedCSIS: Cracow 2013 8 / 21

9. OntoBeef Evaluation Concepts choosing
OntoBeef Evaluation: First Stage
Experts have been asked to choose among all 2344 concepts these
which belong to their domains of interest.
Concepts were displayed one by one. Each of them was represented by
the sequence of synonymous names. An expert could choose between
“Yes” and “No”.
Trójczak, Trypuz (KUL, PZPBM) OntoBeef Ontology FedCSIS: Cracow 2013 9 / 21

10. OntoBeef Evaluation Labels evaluation
OntoBeef Evaluation: Second Stage
Experts were asked to make an order in the labels assigned to each
concept.
Experts might also add a new synonymous label to the concept in any
language.

11. OntoBeef Evaluation Evaluation of the ontological relations
OntoBeef Evaluation: Third Stage
The final stage of the evaluation process was analysis of the
ontological relations in OntoBeef.
For each concept the following information has been provided: its
labels, ancestors, children, siblings and some ontological connections.
The result of this evaluation stage was 494 received submissions.

13. OntoBeef and Linked Open Data
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 a
data 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 an
open license.

17. Applications Thesaurus component
Thesaurus component
Thesaurus component was developed within Java EE plus OWL-API
framework.
It enables you to browse the ontology. Application enables also
registration and after log in allows reporting suggestions and
comments considering concept labels, ancestors, children and other
ontological properties.
In the top application bar there is LOD part, which displays LOD
connections.
