    <Paragraph position="0"> We have presented three ways in which an NLG system that generates object descriptions from symbolic information can exploit OWL ontologies, using M-PIRO's system as an example. First, the NLG system's source symbolic information can be exported in the form of an OWL ontology. Apart from enabling other OWL-aware systems to reuse the source information, this allows the generated texts to be accompanied by OWL descriptions of their semantics, with the OWL ontology establishing the semantic vocabulary. Thus, the semantics of the generated texts become fully accessible to computer applications, such as Web agents. Second, when porting the NLG system to a new domain, it is possible to import a pre-existing OWL ontology, saving a significant amount of effort. Third, it is possible to embed in OWL ontologies all the domain-dependent language resources and user modelling information that NLG systems like M-PIRO's need. This would allow Web sites that carry information about objects to publish their content solely in the form of OWL ontologies, passing the responsibility of generating natural language descriptions to NLG browser plug-ins. The latter requires the NLG community to develop appropriate standards.</Paragraph>
    <Paragraph position="1"> We hope that future work will address the remaining incompatibilities between M-PIRO's technology and OWL. We also plan to explore more fully how NLG engines could become central components of the Semantic Web's browsers, and release prototypes that will demonstrate these ideas.</Paragraph>
