KAON
Encyclopedia
KAON is an ontology
infrastructure developed by the University of Karlsruhe and the Research Center for Information Technologies
in Karlsruhe
.
Its first incarnation was developed in 2002 and supported an enhanced version of RDF
ontologies.
Several tools like the graphical ontology editor OIModeler or the KAON Server were based on KAON.
There are ontology learning
companion tools which take non-annotated natural language text as input: TextToOnto (KAON-based) and Text2Onto (KAON2-based). Text2Onto is based on the Probabilistic Ontology Model (POM).
In 2005, the first version of KAON2 was released, offering fast reasoning support for OWL
ontologies. KAON2 is not backward-compatible with KAON. KAON2 is developed as a joint effort of the Information Process Engineering (IPE) at the Research Center for Information Technologies
(FZI), the Institute of Applied Informatics and Formal Description Methods (AIFB) at the University of Karlsruhe, and the Information Management Group (IMG) at the University of Manchester
.
KAON, TextToOnto, and Text2Onto are open source, based on Java
. KAON2 is not open source, but the executable can be downloaded from the KAON2 site.
Ontology engineering
Ontology engineering in computer science and information science is a new field, which studies the methods and methodologies for building ontologies: formal representations of a set of concepts within a domain and the relationships between those concepts....

Ontology learning
Ontology learning is a subtask of information extraction. The goal of ontology learning is to semi-automatically extract relevant concepts and relations from a given corpus or other kinds of data sets to form an ontology.The automatic creation of ontologies is a task that involves many disciplines...
