Arguments have always played a central role within logic and philosophy. But little attention has been paid to arguments as distinctive kind of discourse, with its own semantics pragmatics. The goal this essay is study the mechanisms by means which we make in starting from argument connectives such ‘therefore’. While some proposals made literature, they fail account for anaphoric behavior ‘ther...

В работе представлен минимальный набор наиболее распространенных аргументативных паттернов современной рекламы; показано, как эти паттерны переносятся на тексты, целью которых не являются продажи, с использованием в качестве эмпирического материала социальной рекламы и политических текстов, предложено теоретическое обоснование предпочтительности представленного набора паттернов. Я полагаю, что ...

This article presents a new approximation method for computing arguments or explanations in the context of logic-based argumentative or abductive reasoning. The algorithm can be interrupted at any time returning the solution found so far. The quality of the approximation increases monotonically when more computational resources are available. The method is based on cost functions and returns lo...

In this paper we propose an argumentative account for a discourse constraint on the reinforcement of some implicatures. We argue that this constraint is not due to the nature of inferences at hand but rather on distinct argumentative relations between the propositions they express. We examine the effect of these relations on the possible discourse relations a speaker is entitled to use in his d...

In comparison with document summarization on the articles from social media and newswire, argumentative zoning (AZ) is an important task in scientific paper analysis. Traditional methodology to carry on this task relies on feature engineering from different levels. In this paper, three models of generating sentence vectors for the task of sentence classification were explored and compared. The ...

In this work we propose a scheme for an Argumentative Dialogue System that allows a user to discuss a certain topic with a virtual agent using natural language. Starting from an agent vs agent case, we address the optimization of the agent strategy by formulating the problem as a Stochastic Game and show that this formalism generally allows the inclusion of additional strategical moves that are...

There are good characterizations of ampliative inference in monotonic theories. However, a problem that faces ampliative inference, in particular abduction, is the explanation of anomalous observations, i. e., observations that are contradictory with the current theory. For this reason, in this work we will consider the problem of embedding abduction of surprising and anomalous observations in ...

This paper presents an argumentation based framework, developed as an extension of an existing framework for nonmonotonic reasoning, in order to support an agent’s self deliberation process. The framework allows the agent to draw conclusions taking into account in a natural way a given preference policy. After developing the argumentation framework we examine two general cases of such argumenta...
