Although South America lost more megafaunal genera than any other continent during the Late-Quaternary Extinction event (LQE), little is known about the chronology, causes or dynamics of these extinctions, especially in the northern part of the continent. Fossil deposits in…

The Paleontology teams at the Universidade Federal do Acre (UFAC) and the Universidade de Brasília (UnB) worked together in order to increase macro and micropaleontological knowledge of the late Miocene rocks exposed at Niterói (10º08'30''S-67º48'46,3''W), on the right margin of…

We show how to interoperate, semantically and inferentially, between the leading Semantic Web approaches to rules (RuleML Logic Programs) and ontologies (OWL/DAML+OIL Description Logic) via analyzing their expressive intersection. To do so, we define a new intermediate knowledge representation (KR)…

Este artículo presenta un nuevo método totalmente automático de
construcción de bases de conocimiento muy densas y precisas a partir de recursos
