Precompiled knowledge support for dynamic argumentation
Capobianco, Marcela - Chesñevar, Carlos Iván - Simari, Guillermo Ricardo

Formato:	Objeto de conferencia, Objeto de conferencia
Enlaces:	Argumentative formalisms have been widely recognized as knowledge representation and reasoning tools able to deal with incomplete and potentially contradictory informa- tion. All such formalisms are computationally demanding. Hence, optimizing argumen- tative systems has been approached from di erent views.
