This thesis addresses the problem of source quality changes in Data Integration Systems. Its main goal is to propose techniques for maintaining as much as possible the satisfaction...
Abstract. In this paper, we present a fast algorithm to answer rangesum queries in OLAP data cubes. Our algorithm supports constanttime queries while maintaining sub-linear time up...
Abstract: There is a lack of a systematic, generic, domain independent objectoriented software engineering process for software familes. In such process a system family should be t...
Abstract. In this work we propose a mechanism which looks at processing the low-level visual information present in video frames and prepares mid-level tracking trajectories of obj...
We describe work done at three sites on designing conversational agents capable of incremental processing. We focus on the `middleware' layer in these systems, which takes ca...
