Managing interschema knowledge is an essential task when dealing with cooperative information systems. We propose a logical approach to the problem of both expressing interschema knowledge, and reasoning about it. In particular, we set up a structured representation language for expressing semantic interdependencies between classes belonging to different(More)
The SEWASIE (SEmantic Webs and AgentS in Integrated Economies) project aims at enabling a uniform access to heterogeneous data sources through an integrated ontology. The overall project development strictly follows a user-centred design methodology. Users have been involved from the very beginning and are constantly participating in the design and testing(More)
Information and communication infrastructures underwent a rapid and extreme decentralization process over the past decade: From a world of statically and partially connected central servers rose an intricate web of millions of information sources loosely connecting one to another. Today, we expect to witness the extension of this revolution with the wide(More)
This article reports a unified methodology developed to evaluate the accessibility and usability of mobile computing applications, which is intended to guarantee universal access as far as possible. As a basis for the methodology, this paper presents an analysis of the accessibility guidelines, conducted to take into account the specificity of mobile(More)
The system presented in the paper is the main result of an on-going European research project WORKPAD (IST- 2005-5-034749) that aims at building 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,(More)
To appear in IEEE Transactions on Data and Knowledge Engineering, 1995-96 1Abstract We describe an approach for multiparadigmatic visual access to databases, which i s proposed to achieve seamless integration of different interaction paradigms. The user i s provided with an adaptive interface augmented by a user model, supporting different visual(More)
