An OWL vocabulary for describing uncertainty metadata.
Meta-Uncertainty
This file specifies the set of OWL classes and properties to represent multi-level uncertainty metadata.
Uncertainty Operation
The Calculus to apply on the Values of a defined Uncertainty Feature.
Uncertainty Value
For each Uncertainty Feature, exists (when declared) a corresponding value.
Meta
The metadata associated to a Sentence in a certain World (Context).
Sentence
The Sentence (Triple, Graph, Graph Pattern) to which Meta is associated in a specific World.
Uncertainty
A subclass of Meta, it enables annotating the Sentence associated to the metadata with uncertainty information.
World
The context (Graph, Default Graph, etc.) in which the Sentence is associated to Meta. This is used generally by datastores which are unable to represent named graphs.
Uncertainty Approach
Individuals of this class represent uncertainty approaches, which are detailed in the appendix A.
Translation Function
Individuals of this class are LDScript functions enabling translating uncertainty information from one approach to another.
uncertaintyOperator
Each Uncertainty approach has its own logic to reason over metadata, This class defines the methods that can be applied over Uncertainty Values. Such logic is the same used in reasoners and inference engines.
uncertaintyFeature
Each Uncertainty approach has some features, which can be metrics or measures to compare, infer or reason over to have a decision about knowledge.
