Fonseca's research interests are in the areas of ontologies, environment, and integration. My basic work is on ontology engineering, which is the construction of ontologies, of how people understand and represent their knowledge about a subject. My preferred subject for ontologies is the environment, .i.e, ontologies that describe how the environment works or better how we think the environment works. Once we have different representations of the understanding of different people I am interested in how to integrate these different views. The integration of different ontologies will lead to a better understanding among different communities. The result of the integration can be used in different enterprises such as creating better public policies and enhance knowledge sharing among different nations of the planet.The main objectives of my current research are: (1) Performing an empirical study of how different communities conceptualize and categorize scientific information about the environment; (2) Creating multiple ontologies about the environment; (3) Designing computational models to specify, represent, visualize, access, compare and share multiple ontologies of scientific information.
