Debugging grid systems is complex, mainly because of the probe effect and non reproducible execution. The probe effect arises when an attempt to monitor a system changes the behav...
This paper proposes a methodology for the eustomisation of natural language interfaces to information retrieval applications. We report a field study in which we tested this metho...
We present a new interface for Object-Oriented Database Management Systems (OODBMSs). The GOODIES1 system combines and expands the functions of many existing interface systems, in...
