Graphical knowledge based electronic mail system (GKBEMS)

An electronic mail system, built on a distributed knowledge base and providing a set of useful operations in the very comfortable way, is described. In fact, all of the advanced mail operations provided by the system are based on a good and precise description of documents and users. Such operations simplify finding useful information about existing documents, sending the documents without specifying the user´s address, and prioritizing, sorting, selecting, discharging, and forwarding mail. Electronic mail operations are also improved with the possibility of easier processing of the external documents and exploiting the capabilities of a modern workstation equipped with image input-output devices
