Ontologies based on natural language semantic are supposed to represent the mental models that speakers of a language possess of domains. They are thus commonly understood and may serve as a efficient means for communication between humans and computers. A menu based on a taxonomy extracted from such an ontology may therefore serve as interface for a web site communicating information about the corresponding domain. To determine an ontological representation of a mental model one must consider not only the meaning of isolated words, but also how they enter into true sentences and valid inferences. In this paper a method is presented that consists in identifying true sentences and using valid inferences to construct taxonomies for categorisation hierarchies. The method is discussed and then applied to the construction of a taxonomy for the domain of tasks provided by the Norwegian municipalities.
