Some DLV Applications for Knowledge Management

Abstract. Even if the industrial exploitation of the DLV system has started very recently, DLV already has a history of applications on the industrial level. The most valuable applications from a commercial viewpoint are those in the area of Knowledge Management. They have been realized by the company EXEURA s.r.l. -a spin-off company of the University of Calabria having a branch also in Chicago -with the support of the DLVSYSTEM s.r.l..

After briefly describing these KM products, we report on their recently-released successful applications
