FrameNet-RDF

FrameNet is an important lexical knowledge base featuring cognitive plausibility, and grounded in a large corpus. Besides being actively used by the NLP community, frames are a great source of knowledge patterns once converted into a knowledge representation language. In this paper we present our experience in converting the 1.5 XML version of FrameNet into RDF datasets published on the Linked Open Data cloud, which are interoperable with WordNet and other resources. In the conversion we have used Semion, a new tool that allows a rule-based, customized pipeline from XML to RDF and OWL data. In addition, we introduce a method to select and refactor part of the information related to frames as full-edged OWL knowledge patterns. This last result has required non-trivial assumptions on how to interpret FrameNet relations as formal knowledge.

The paper presented at K-Cap 2011 is available here.

Ontology

The FrameNet ontology is available here. A graphical representation of the ontology using WebVOWL is available here, and documentation about the ontology is also available in the format of the Live OWL Documentation Environment (LODE). The ontology and the data can be queried through a dedicated SPARQL Endpoint (use the dataset with ID 'framenet-owl'). The following is an example of SPARQL query that allows to query the ontology in order to gather all the axioms associated with the class Frame.

PREFIX fn-owl: <http://www.ontologydesignpatterns.org/ont/framenet/tbox/>
SELECT ?p ?o
FROM<framenet-owl>
WHERE{
  fn-owl:Frame ?p ?o
}

Data

Data of FrameNet-RDF are available are available here as a single Turtle dump. Additionally, data can be accessed via HTTP requests (e.g., http://www.ontologydesignpatterns.org/ont/framenet/abox/frame/Abandonment). Finally, the data can be queried through a dedicated SPARQL Endpoint (use the dataset with ID 'framenet-rdf'). The following is an example of SPARQL query that allows to query the ontology in order to gather all the axioms associated with the frame Abandonment.

SELECT ?p ?o
FROM <framenet-rdf>
WHERE{
  <http://www.ontologydesignpatterns.org/ont/framenet/abox/frame/Abandonment> ?p ?o
}
