Get a quick sense of what's OntoPortal with our short presenting paper . Please, use this to reference to our work too.
Save and find semantic artefacts
The primary mission of an OntoPortal installation is to host and serve ontologies and semantic artefacts. The portals accept resources in multiple knowledge representation languages: OWL, RDFS, SKOS, OBO and UMLS-RRF.
Ontologies are semantically described with rich metadata (partially extracted from the source files), and a browsing user interface allows to quickly identify, with faceted search, the ontologies of interest based on their metadata.
Browse the content of semantic artefacts
OntoPortal lets users visualize a class/concept or property within its hierarchy, as well as see related information for this entity (as relations included in the source file).
Search for terms
All the semantic artefacts content hosted in an OntoPortal is indexed and can easily be retrieved.
Much more available as standard OntoPortal services...
-
Custom hostingOrganize public/private ontologies, group/categorize them and offers custom slices.
-
VersioningStore all ontology versions, whether manually submitted or automatically pulled. Get diff between versions.
-
WidgetsEasily embed Web widgets in external web applications to facilitate the reuse/visualization of ontology entities.
-
MappingsStore, retrieve and explore mappings between ontology terms. Get lexical overlap of an ontology with all the other ones in a portal.
-
CommunityGet notified from feedback as notes, change requests and record projects using ontologies.
-
AnnotatorIdentify semantic artefact classes or concepts inside any raw text.
-
RecommenderGet ontology recommendations for a provided text or keyword list.
-
Automated accessAccess all content and services with two different endpoints: a REST web service API that returns JSON-LD and a SPARQL endpoint.
And even more additional features and services developed by the Alliance...
-
Enhanced mapping featuresMore flexible mapping storage, import mappings in bulk or extract SKOS mappings explicitly defined in semantic artefact source files.
-
Enhanced semantic annotation workflowNatural language-based enhancements of the Annotator with scoring methods context detection (e.g., negation, temporality).
-
Extended ontology metadata modelExtended and harmonized metadata model based on MOD1.4 to better support descriptions of ontologies and their relations.
-
Semantic artefact FAIRness assessmentGet FAIR score for each semantic artefact from 61 questions implemented from the Ontology FAIRness Evaluation (O’FAIRe) methodology.
-
Extended SKOS supportFull support of SKOS and innovative browsing approaches to discover and navigate concepts in SKOS thesauri that make extensive use of scheme and collections.
-
Assigning DOIsRequest a Digital Object Identifier (DOI) for resources hosted in the portal using Datacite services.
