This ontology describes the path observed in linked data datasets. It defines paths in terms of their length, their elements, and the number of its occurrences in a certain dataset. Path elements are composed of properties occurring at a certain position in the path, and indicate their subject and object types.
contains property at position 1
contains property at position 2
contains property at position 3
contains property at position 4
A relation between a path and its path elements.
A relation between a property and its object type.
A relation between a property of a path element and its subject type.
A relation between a path element and a property of the path it is member of.
nel dataset
Indicates the length of a path.
Indicates the number of occurrences of a path in a dataset.
has path density for length 2
The level 2 path density of a given dataset. It is calculated for dataset "d" as follows:
|P so that P in d| / |P so that P in some PA_2 in d|
has path density for length 3
The level 3 path density of a given dataset. It is calculated for dataset "d" as follows:
|P so that P in d| / |P so that P in some PA_3 in d|
has path density for length 4
The level 4 path density of a given dataset. It is calculated for dataset "d" as follows:
|P so that P in d| / |P so that P in some PA_4 in d|
The ratio between the total amount of observed paths of length 2 in this dataset and the total number of potential paths, also of length 2, computed over the same properties as the dataset. Neither path category is counting types in this case.
The ratio between the total amount of observed paths of length 3 in this dataset and the total number of potential paths, also of length 3, computed over the same properties as the dataset. Neither path category is counting types in this case.
The ratio between the total amount of observed paths of length 4 in this dataset and the total number of potential paths, also of length 4, computed over the same properties as the dataset. Neither path category is counting types in this case.

A path is described through an ordered list of properties, which are used in the triple sequences that instantiate the path. Each property is associated to a position in the path, a subject type, and an object type. Hence, we define a path as composed by a number of path elements equal to its length. A path has (i) a length (min 2), given by the number of properties that compose it, (ii) a number of occurrences, which is the number of its instances in the analysed dataset.
