OWL2NL

About

OWL2NL allows for converting OWL axioms into natural language.

Example

Suppose we have the following axioms in Description Logic syntax:

∃ hasDegree.⊤ ⊑ Person
Parent ≡ Animal ⊓ (≥ 1 hasChildren.⊤)
Student ≡ Person ⊓ (∃ hasHabitat.University) ⊓ (∃ isHardWorking.{true})

OWL2NL will convert the first axiom into

Everything that has a degree is a person.

the second one into

Every parent is an animal that has at least 1 child.

and the last one into

Every student is a person that has as habitat an university and that is hard working.

Setup

From Source

To install Triple2NL you need to download it via Git and install it via Maven.

git clone https://github.com/AKSW/SemWeb2NL.git
cd SemWeb2NL
mvn clean install

Afterwards you have to add the dependency to your pom.xml

<dependency>
  <groupId>org.aksw</groupId>
  <artifactId>OWL2NL</artifactId>
  <version>0.1-SNAPSHOT</version>
</dependency>

Using Maven Release

1. Add AKSW Maven repository to your pom.xml

<repository>
  <id>maven.aksw.internal</id>
  <name>University Leipzig, AKSW Maven2 Repository</name>
  <url>http://maven.aksw.org/archiva/repository/snapshots</url>
</repository>

<repository>
  <id>maven.aksw.internal</id>
  <name>University Leipzig, AKSW Maven2 Internal Repository</name>
  <url>http://maven.aksw.org/archiva/repository/internal</url>
</repository>

2. Add dependency to your pom.xml

<dependency>
  <groupId>org.aksw.semweb2nl</groupId>
  <artifactId>OWL2NL</artifactId>
  <version>0.1-SNAPSHOT</version>
</dependency>

Usage

// the ontology we're working on
OWLOntology ontology = ...

// the axiom we want to convert
OWLAxiom axiom = ...

// create the axiom converter
OWLAxiomConverter converter = new OWLAxiomConverter(ontology);
		
// convert the axiom into natural language
String text = converter.convert(axiom);
