Article
To counter the fake news phenomenon, the scholarly community has attempted to debunk and prebunk disinformation. However, misinformation still constitutes a major challenge due to the variety of misleading techniques and their continuous updates which call for the exercise of critical thinking to build resilience. In this study we present two open...

Fallacies are used as seemingly valid arguments to support a position and persuade the audience about its validity. Recognizing fallacies is an intrinsically difficult task both for humans and machines. Moreover, a big challenge for computational models lies in the fact that fallacies are formulated differently across the datasets with differences...

In response to the ever-increasing spread of online disinformation and misinformation, several human–computer interaction tools to enhance data literacy have been developed. Among them, many employ elements of gamification to increase user engagement and reach out to a broader audience. However, there are no systematic criteria to analyze their rel...
Conference Paper
Recommendation systems (RS) play a crucial role in influencing our daily decision-making practices and choices, such as healthy diets. However, arguments in support of a diet recommendation, which are embedded in the algorithmic design of the RS, tend to be redundant, and predominantly based on the past choices of the users or their peers, thus hin...
Article
This study extends the rhetorical arena approach to crisis communication with an argumentative perspective. A rhetorical activity in which reasons are communicated to justify and obtain acceptance for a claim, argumentation plays a crucial role in (re)legitimizing corporate trustworthiness following a crisis episode. Arguments supporting or rejecti...
Preprint
Human communication often involves the use of verbal irony or sarcasm, where the speakers usually mean the opposite of what they say. To better understand how verbal irony is expressed by the speaker and interpreted by the hearer we conduct a crowdsourcing task: given an utterance expressing verbal irony, users are asked to verbalize their interpre...

Trust-oriented argumentation in rhetorical sub-arenas: from corporate communication to online stakeholder discussions. The "The Facts About Facebook" case. Rudi Palmieri [0000−0002−5122−3058] and Elena Musi [0000−0003−2431−455X] Abstract. This paper lays the foundations for a research project aimed at analysing trust-oriented argumentation in crisi...
Article
This article offers a first large scale analysis of argumentative polylogues in the fracking controversy. It provides an empirical methodology (macroscope) that identifies, from large quantities of text data through semantic frame analysis, the many players, positions and places presumed relevant to argumentation in a controversy. It goes beyond th...
Article
Full-text available
A macroscope is proposed and tested here for the discovery of the unique argumentative footprint that characterizes how a collective (e.g., group, online community) manages differences and pursues disagreement through argument in a polylogue. The macroscope addresses broader analytic problems posed by various conceptualizations of large-scale argum...
Article
In Discourse Studies concessions are considered among those argumentative strategies that increase persuasion. We aim to empirically test this hypothesis by calculating the distribution of argumentative concessions in persuasive vs. non-persuasive comments from the the ChangeMyView subreddit. This constitutes a challenging task since concessions do...

Article
In everyday communicative arenas, we engage in critical discussions to persuade others to change their views about issues of personal as well as public interest. Discourse analysts have deemed concessions as privileged strategies to manage disagreement and reach consensus. However, a coherent and comprehensive account of the argumentative functions...
Chapter
This study addresses appearance verbs as argumentative indicators of defeasible reasoning in opinion articles, taking as a case study the Italian verb sembrare (‘seem’). Appearance verbs, due to their epistemic-modal and evidential-inferential features point to the presence of premises-conclusion relations. Moreover, their lexical semantics further...
Article
Full-text available
Argumentative indicators of discourse relations constitute crucial cues for the mining of arguments. However, acomprehensive lexicon of these linguistic devices is so far lacking due to the scarcity of corpora argumentatively annotated and the absence of an empirically validated analytic methodology. Recent studies have shown that modals, that expr...

In this paper we investigate the interface between the semantics and the discourse functions of the Italian modal adjective possibile (‘possible’) in a corpus of economic-financial news. The aim is to show how a context-dependent semantic analysis of the adjective sheds light on the distinctive role played by possibile at a discourse level, in part...

Full-text available
Based on an Italian corpus of contributions to comment spaces of online reviews in different domains, we argue that some of these contributions are user reviews. We show that users position themselves as legitimate contributors by conforming to genre conventions that are central in official reviews, in particular to the requirement that the reviewe...

This paper investigates lexical evidentials in an English corpus of opinion articles about oil drilling issues in USA. It will be shown through a multilevel annotation that evidentials, depending on their lexical semantics, indicate specific types of standpoints and premises as far as (inter)subjectivity and objectivity are concerned.
Article
Adversative connectives such as alternatively, conversely, besides, while, recurrently have lexical sources belonging to the spatial-temporal dimension. Nevertheless, they develop over time different contrastive values such as opposition, correction and counterexpectation. In this paper, I analyze the semantic change of two Italian adversative conn...

Questo lavoro propone un’analisi semantica della parola ‘argomento’ nella Divina Commedia adottando il punto di vista della teoria dell’argomentazione. Il termine ‘argomento’, polisemico sin dalle sue origini latine, oltre a indicare il tema di un discorso, fa parte del lessico tecnico dell’argomentazione. I risultati dell’analisi mostrano che i) i...

This contribution aims at providing an argumentative method to account for epistemic modality and evidentiality. I claim that these two linguistic categories can work as semantic components of defeasible argumentative schemes based on classification processes. This kind of approximate reasoning is, in fact, frequently indicated by appearance verbs...

The research project, financed by the Swiss National Foundation, was carried out at the Faculty of Communication Sciences of USI Università della Svizzera italiana from September 1st, 2012 till September 1st 2015. It investigated evidential markers, i.e. the set of linguistic means by which speakers signal sources of information of asserted contents. Information source is a fundamental semantic-pragmatic category that may be expressed by a large range of different linguistic means. Main types of information source are direct perception, hearsay and inference. The project concentrated on the latter type of source. In Italian, as in other European languages, a common means to signal that an assertion is based on inference are perception verbs. These are indeed not only used to report direct perception of an object or event (e.g. l’ho visto partire ‘I saw him leave’), but also to indicate a process of reasoning, which may be based partly on perceptual evidence (e.g. vedo che è partito ‘I see that he has left’, sembra essere partito ‘he seems to have left’), but may also lack reference to perceptual data (e.g. sembra un momento propizio ‘this seems a propitious moment’). Which semantic, argumentative and textual properties of perception predicates favor their (re)interpretation as inferential markers? Which types of reasoning do these markers signal? The research project intended to answer these questions by studying constructions with perception verbs in a broad sense (including verbs of appearance) in the Italian language and the ways they are used in various types of discourse. A mainly synchronic, corpus-based approach was adopted. Two sets of discourse genres, i.e. reviews and editorials, were investigated in particular detail, hypothesizing that they illustrate a large variety of uses of the expressions analyzed.
