PROTON (PROTo ONtology) was developed in the SEKT project as a lightweight upper-level ontology, serving as a modeling basis for a number of tasks in different domains. To mention just a few applications: PROTON is meant to serve as a seed for ontology generation (new ontologies constructed by extending PROTON); it can be used for automatic entity recognition and more generally Information Extraction (IE) from text, for the sake of semantic annotation (metadata generation). PROTON was extended to cover the conceptual knowledge encoded within the most popular datasets from Linked Open Data like DBPedia, GeoNames, etc.
PROTON is split into 2 modules, which have the following URIs:
Proton has two types of documentation:
PROTON is used in various projects around the world, for example:
Proton is also used as a reference layer which facilitates the access and navigation to a segment of LOD cloud in FactForge.
