In complex emergency scenarios, teams from various emergency-response organizations must collaborate. These teams include both first responders, such as police and fire departments, and those operators who coordinate the effort from operational centers. The Workpad architecture consists of a front- and a back-end layer. The front-end layer is composed of(More)
Data Grids allow for seeing heterogeneous, distributed, and dynamic informational resources as if they were a uniform, stable, secure, and reliable database. According to this view, current proposals for data integration on Grids are based on the notion of global schema built over a collection of autonomous information sources. On the other hand, in dynamic(More)
Senso Comune is an open-knowledge base for the Italian language, available through a Web-based collaborative platform, whose construction is in progress. The resource integrates dictionary data coming from both users and legacy resources with an ontological backbone, which provides foundations for a formal characterization of lexical semantic structures(More)
In this paper we study a DL rich enough to express UML class diagrams including ISA and disjointness between classes (but not covering constraints), typing of associations, and participation and functional cardinality constraints. For such a DL, which we call DL-Lite, we propose novel reasoning techniques for a variety of tasks, notably including query(More)
In this paper, we present a recently funded European research project, namely WORKPAD, that aims at designing and developing an innovative software infrastructure (software, models, services, etc.) for supporting collaborative work of human operators in emergency/disaster scenarios. In such scenarios, different teams, belonging to different organizations,(More)
Although service-oriented architectures go a long way toward providing interoper-ability in distributed, heterogeneous environments, managing semantic differences in such environments remains a challenge. We give an overview of the issue of semantic interoperability (integration), provide a semantic characterization of services, and discuss the role of(More)
In this paper, we present the architecture of the research project WORKPAD 1. This project aims at designing and developing an innovative service-oriented software infrastructure for supporting collaborative work of human operators in emergency/disaster scenarios. In such scenarios , different teams, belonging to different organizations, need to collaborate(More)
