Overview

This page describes the process of generating an OWL Ontology using the OwlExporter and annotations created by an existing GATE application. The OwlExporter is an application independent Processing Resource that can be included as part of any GATE pipeline that creates annotations that need to be exported to a Web Ontology Language (OWL) Model.

Screenshot of the OwlExporter's Mapping Annotations

The OwlExporter provides a mapping between NLP and domain annotations, and the concepts and relations of an existing domain-specific and NLP ontology. The former can then be exported in the form of individuals and the latter as datatype or object properties. The populated ontology can then be used within any ontology-enabled tool for further querying, reasoning or visualization.

A Representation of the Exported Domain and NLP Ontologies

The OwlExporter is able to populate a domain ontology modelling a domain (e.g., biology, software engineering); and an NLP ontology that models concepts and relationships commonly used in language engineering.

Documentation

In order to run the demos below:

Download, install and configure GATE
Download, install and configure ANT
Download and install the OwlExporter
Create an ANNIE pipeline
Include the Jape Grammars contained in the demos
Include the OwlExporter in the ANNIE pipeline
Configure the OwlExporter to use the ontology models contained in the demos
Add a corpus of your choice
Run the pipeline

For a detailed explanation of the above steps, please refer to the OwlExporter documentation included in the “Download ” section below.
