Advanced Traveler Information Systems (ATIS) require e cient information retrieval and updating in a dynamic environment at di erent geographical scales. ATIS applications are use...
In this paper, we describe a system called XomatiQ to address the problem of integration, querying and correlation of biological data. XomatiQ is an integral part of the genomics ...
The work reported here lays the foundations of data exchange in the presence of probabilistic data. This requires rethinking the very basic concepts of traditional data exchange, ...
In this paper, we propose a new technique for multidimensional query processing which can be widely applied in database systems. Our new technique, called tree striping, generalize...
Information retrieval techniques have to face both the growing amount of data to be processed and the "natural" distribution of these data over the network. Hence, we in...
