Recently, we have started a new line of research where we are developing web infrastructure for reasoning. Currently, DeLP has been wrapped as a Web Service and a Visualization Web Service has been implemented to provide a more useful interaction with the dialectical trees that are the result of the argumentation process necessary to answer queries. A preliminary beta version of these services can be found in http://lidia.cs.uns.edu.ar/ws_delp/.
