An approach to decision making based on dynamic argumentation systems
(Elsevier Science, 2017-01)
In this paper we introduce a formalism for single-agent decision making that is based on Dynamic Argumentation Frameworks. The formalism can be used to justify a choice, which is based on the current situation the agent ...
Bipolarity in temporal argumentation frameworks
(Elsevier Science Inc, 2017-02)
A Timed Argumentation Framework (TAF) is a formalism where arguments are only valid for consideration during specific intervals of time, called availability intervals, which are defined for every individual argument. The ...
Modeling time and valuation in structured argumentation frameworks
(Elsevier, 2015-01)
Temporal Argumentation Frameworks (TAF) represent a recent extension of Dung's abstract argumentation frameworks that consider the temporal availability of arguments. In a TAF, arguments are valid during specific time ...
Inconsistent-tolerant base revision through Argument Theory Change
(OXFORD UNIV PRESSOXFORD, 2012)
Reasoning and change over inconsistent knowledge bases (KBs) is of utmost relevance in areas like medicine and law. Argumentation may bring the possibility to cope with both problems. Firstly, by constructing an argumentation ...
Ontology Reasoning and Evolution with Inconsistency Tolerance: An Argumentative Approach to Revision of Description Logics
(IOS Press, 2016-03-02)
Reasoning and change over inconsistent ontologies (i-ont(s)) is of utmost relevance in sciences like medicine and law. Argumentation may be an appropriate formalism to cope with both problems: (reasoning) through an ...
A Petri Net Model of Argumentation Dynamics
(Springer, 2014-09)
Petri nets are a mathematical modelling tool suitable for describing dynamic computational systems. In this work we present a formalization of abstract argumentation frameworks using Petri nets, where arguments and ...
A theoretical framework for trust-based news recommender systems and its implementation using defeasible argumentation
(World Scientific, 2013-08)
Although the importance of trust in recommender systems is widely recognized, the actual mechanisms of trust propagation and trust preservation are poorly understood. This is partly due to the fact that trust is a ...
Using argument strength for building dialectical bonsai
(Springer, 2013-03)
Argumentation in AI provides an inconsistency-tolerant formalism capable of establishing those pieces of knowledge that can be accepted despite having information in contradiction. Computation of accepted arguments tends ...
The Gluon Mass Generation Mechanism: A Concise Primer

Global environmental change effects on ecosystems: The importance of land-use legacies
(Wiley Blackwell Publishing, Inc, 2016-04)
One of the major challenges in ecology is to predict how multiple global environmental changes will affect future ecosystem patterns (e.g. plant community composition) and processes (e.g. nutrient cycling). Here, we highlight ...
