OntoBeef Domain is based on an OWL version of DOLCE as a foundational ontology. Let us mention here four top classes of DOLCE important for structuring all OntoBeef classes. DOLCE distinguishes:

  • endurants (i.e. entities ‘wholly’ present at any time of their existence”, e.g., Bovinae),
  • perdurants (‘i.e. ‘entities that ‘happen in time’, e.g., Feeding),
  • qualities (i.e. entities that can be perceived or measured, e.g., Tenderness) and
  • regions (i.e. quality spaces providing values used for measuring qualities, e.g., pH).



OntoBeef isn used as the basis for many applications (see picture below).

Let us point out two of them:

  1. The first one is a Java desktop application named Oxpecker (see  section V of the paper]). It facilitates the access to the database of descriptions of scientific articles, which were collected in the project. The database contains descriptions of around 2800 articles. It collects information about the structure of papers (title, author(s), abstract, etc.) and some content data such as definitions of terms, scientific laws and rejected hypotheses. Oxpecker uses the annotation of articles by IRIs of OntoBeef classes to find articles which best match the user’s query.
  2. The other OntoBeef-driven application is a web application which at the beginning served as a thesaurus. It enabled us to search for categories and had a Linked Open Data connections to four external ontologies. Recently the application got some functionalities of Oxpecker and for each OntoBeef class it provides the scientific laws which govern its instances.
