The [DBpedia Archivo Databus agent](https://databus.dbpedia.org/ontologies) generates only basic, static documentation for the archived snapshots of the ontologies. More, augmented and dynamic information for this ontology is rendered on and retrievable via [DBpedia Archivo Frontend](http://archivo.dbpedia.org/info?o=http://premon.fbk.eu/ontology/pb).

## Ontology Metadata

DBpedia Archivo extracts metadata from the ontology for well known properties (e.g. dct:description). This subsection shows the content of every property individually using a separate heading.

### dct:description

We define classes [pmopb:Roleset](http://premon.fbk.eu/ontology/pb#Roleset) and [pmopb:SemanticRole](http://premon.fbk.eu/ontology/pb#SemanticRole) as subclasses of [pmo:SemanticClass](http://premon.fbk.eu/ontology/core#SemanticClass) and [pmo:SemanticRole](http://premon.fbk.eu/ontology/core#SemanticRole), respectively.

Each [pmopb:SemanticRole](http://premon.fbk.eu/ontology/pb#SemanticRole) instance is related (via property [pmopb:argument](http://premon.fbk.eu/ontology/pb#argument)) to exactly one [pmopb:Argument](http://premon.fbk.eu/ontology/pb#Argument), which is defined as the disjoint union of three subclasses: 

* [pmopb:NumberedArgument](http://premon.fbk.eu/ontology/pb#NumberedArgument), containing the individuals corresponding to numbered arguments (e.g., *Arg0*, *Arg1*); 
* [pmopb:Modifier](http://premon.fbk.eu/ontology/pb#Modifier), containing the
individuals corresponding to modifiers (e.g., *ArgM-LOC*, *ArgM-TMP*). While PB annotation guidelines define a single modifier (*ArgM*) with multiple function tags (e.g., *LOC*, *TMP*), we opt to specialize the modifier for each function tag, similarly to the way these arguments are actually annotated by state-of-the-art SRL tools; and, 
* [pmopb:SecondaryAgent](http://premon.fbk.eu/ontology/pb#SecondaryAgent), containing the single individual annotating secondary agents (*ArgA*). 

Property [pmopb:tag](http://premon.fbk.eu/ontology/pb#tag) enables associating possible tags, either a [pmopb:Modifier](http://premon.fbk.eu/ontology/pb#Modifier) or some additional tag defined in class [pmopb:Tag](http://premon.fbk.eu/ontology/pb#Tag), to [pmopb:SemanticRole](http://premon.fbk.eu/ontology/pb#SemanticRole)s, or [nif:Annotation](http://persistence.uni-leipzig.org/nlp2rdf/ontologies/nif-core#Annotation)s of semantic roles in examples.

Additional classes (and related properties) are defined to represent inflectional information about examples: [pmopb:Inflection](http://premon.fbk.eu/ontology/pb#Inflection), [pmopb:Person](http://premon.fbk.eu/ontology/pb#Person), [pmopb:Tense](http://premon.fbk.eu/ontology/pb#Tense), [pmopb:Aspect](http://premon.fbk.eu/ontology/pb#Aspect), [pmopb:Voice](http://premon.fbk.eu/ontology/pb#Voice), and [pmopb:Form](http://premon.fbk.eu/ontology/pb#Form).

### rdfs:comment

The PropBank module of the PreMOn ontology extends the core module for representing concepts specific to PropBank. The modelling is based on the [PropBank guidelines] (http://clear.colorado.edu/compsem/documents/propbank_guidelines.pdf).
