v0.3: - Universe subclasses except for TopLevelUniverse are now deprecated. All properties and restrictions encompassing these Universe specializations now point to Universe - ObservedUniverseInDataset was renamed to UniverseObservation and directly subsumes owl:Thing - UniverseObservation has no dataset relations, so the same stats can be observed for different datasets - PropertyUsageInDataset now has existential restriction on UniverseObservation - Related object properties renamed acordingly
v0.4: - Renamed all namespace occurrences in the model starting with "http://ontologydesignpatterns.org" to "http://www.ontologydesignpatterns.org"
v0.5: - Added custom isDefinedBy object property
in dataset
A relation between a universe and the domain in it.
A relation between a universe or top level universe and its object type i.e. the range.
A relation that assigns a universe to a property. It is implied when a certain universe is observed in a linked dataset for that property.
A relation between a universe and the range in it.
A relation between a universe or top level universe and its subject type i.e. the domain.
A relation that assignes a top level universe to a property. It is implied when the universe of a property is aligned to a top level universe. Top level universes are composed of top level classes, typically belonging to general content patterns extracted from foundational ontologies.
A relation between a property and a top level property. Indicates that the property is either rdfs:subPropertyOf or a owl:equivalentProperty to a top level property.
A relation between a class (type) and a top level class (type). Indicates that the class is either rdfs:subClassOf or a owl:equivalentClass to a top level type.
A relation between the universe of a property (as it is observed in linked datasets) and a top level universe. A top level universe is composed of top level classes, typically very general classes belonging to content patterns extracted from foundational ontologies.
An absolute (non-normalized) value indicating the amount of observed paths a certain property has been found to belong to, either per se or by specific dataset. Its value "x" calculated as follows for each P, or for each P in a given dataset D: x := |P so that P in PA|
An absolute (non-normalized) value indicating the amount of observed paths of length 2 a certain property has been found to belong to, either per se or by specific dataset. Its value "x" calculated as follows for each P, or for each P in a given dataset D: x := |P so that P in PA_2|
An absolute (non-normalized) value indicating the amount of observed paths of length 3 a certain property has been found to belong to, either per se or by specific dataset. Its value "x" calculated as follows for each P, or for each P in a given dataset D: x := |P so that P in PA_3|
An absolute (non-normalized) value indicating the amount of observed paths of length 4 a certain property has been found to belong to, either per se or by specific dataset. Its value "x" calculated as follows for each P, or for each P in a given dataset D: x := |P so that P in PA_4|
normalized CF, absolute CF divided by the number of paths of length 2 in a certain dataset
normalized CF, absolute CF divided by the number of paths of length 3 in a certain dataset
normalized CF, absolute CF divided by the number of paths of length 4 in a certain dataset
the ratio between the normalized clustering factor and the normalized number of triples of a property (in a certain dataset)
the number of triples of a property divided by the total number of triples (in a certain dataset)
The defined universe of a property refers to its domain and range as they are asserted in the original vocabulary when the property is defined.
The observed universe of a property indicates what are the subject types and object types as they are actually used in linked datasets.
An n-ary relation between a property, a dataset, and the number of triples of that property in the dataset.
A general property tyically defined in a general content pattern extracted from a foiundational ontology.
A general class, typically defined in a content pattern extracted from a foundational ontology.
A special type of universe, where domain and range are top level classes, typically belonging to general content patterns extracted from foundational ontologies.
A [domain, range] pair for an OWL or RDFS property
This is an n-ary relation between a property, a dataset, a universe (as it is observed in a linked dataset), the percentage of the subject type and the percentage of the object type. It indicates what universes are observed for that property in a certain dataset and with the respective percentage for subject and object types.
