Uma linguagem para formalização de discursos com base em ontologias

This research proposes the information architecture of a textual formal language to represent and reason about ontological entities based on foundational ontologies. Through metamodeling, the language is able to deal with heterogeneous ontologies that can be described as instances of one or more foundational ontology. The language provides classic and modal inference mechanisms supported by proof notions based on the (Modal) Logic Programming paradigm. The modalities introduced by the modal framework allow a wide range of interpretations, including multi-agent systems. A systematization of the endurant fragment of the Unified Foundational Ontology (UFO) is produced in order to compose part of the theoretical framework underlying the proposal, and to serve as an example instantiating the developed framework. As complementary results we highlight: a systematization of an extended set of rules for conceptual modeling and a detailed glossary of terms and concepts of UFO-A; functional prototypes implementing the developed systems; translations of the theories described as instances of the framework to diagramatic representations, as extensions of the OntoUML visual language; and discussions regarding the integration of Information Architecture, Conceptual Modeling and Logic Programming within Applied Social Science.
