W artykule opisano niewielką część spośród wielu inicjatyw podejmowanych w celu stworzenia Web 3.0. Pozwoliło to jednak na zarysowanie kontekstu dla nowego problemu naukowego, który jest przedmiotem badań autorów. Aksjologiczne wartościowanie prawdziwości danych wymaga budowy algorytmów, które bazując na dodatkowych informacjach dołączanych do dokumentów sieciowych, będą prowadzić do obliczenia ich...
We consider argumentation systems taking into account several attack relations of different strength. We focus on the impact of various strength attacks on the semantics of such systems, and particularly on the decision problem of credulous acceptance: namely, focussing on one particular argument, a classical issue is to compute a proof, under the form of an admissible set containing this argument...
In the domain of classical planning one distinguishes plans which are optimal in their number of actions, they are referred as sequential plans, from plans which are optimal in their number of levels, they are referred as parallel plans. Searching optimal sequential plans is generally considered harder than searching optimal parallel plans. Buttner and Rintanen have proposed a search procedure which...
A conversational recommender system iteratively shows a small set of options for its user to choose between. In order to select these options, the system may analyze the queries tried by the user to derive whether one option is dominated by others with respect to the user's preferences. This paper describes a framework for preference dominance. Two instances of the framework are developed for query...
