Janus: Automatic Ontology Construction Tool

The construction of an ontology for a large domain still remains an hard human task. The process is sometimes assisted by software tools that facilitate some parts of the construction and evolution life-cycle. But they do not propose a methodology that considers the automation of the entire process. In this paper we present a method for deriving automatically an ontology. Then, we introduce Janus, an implementation of this approach, for deriving automatically a skeleton of an ontology from XML schema files in a given domain. Janus also provides different useful views that can be used for a final revision by an expert.
