OWL instance data evaluation, identified by our previous work, is to check whether the instance data conforms to the semantic expectation of its targeting applications. We have identified some integrity issues raised by applications demanding closed world reasoning. In this paper, we present a formal characterization of those integrity issues using autoepistemic operators. This approach allows ...

To tackle urban heterogeneity and complexity, several indices have been proposed, commonly aiming to provide information for decision-makers. In this study, we propose a novel customizable procedure quantifying ecosystem integrity. Based on citywide approach, developed an easy-to-use index that contrasts physical biological variables of ecosystems with given reference system. The Urban Ecosyste...

In this paper two external schema generation algorithms are presented. These algorithms are defined in the framework of the new external schema definition methodology for OODBs put forward in (Samos, 1995); they generate an external schema from a set of classes selected from those existing in an external schema definition repository. Their main characteristic is that they avoid the generation o...
