Ironic Gestures and Tones in Twitter

چکیده
English. Automatic irony detection is a young field of research related to Sentiment Analysis. When dealing with social media data, the shortness of text and the extraction of the statement from his context usually makes it hard to understand irony even for humans but especially for machines. In this paper we propose an analysis of the role that textual information plays in the perception and construction of irony in short texts like tweets. We will focus on the impact of conventional expedients of digital writing, which seem to represent a substitution of typical gestures and tones of oral communication, in figurative interpretation of messages in Italian language. Elaborated computational model has been exploited in the development of an irony detection system, which has been evaluated in the Sentipolc’s shared task at EVALITA 2016. Italiano. Il riconoscimento automatico dell’ironia è un ambito di ricerca giovane, rilevante per la Sentiment Analisys. Quando si tratta di social media data, la brevità del testo e la sua estrazione dal contesto rendono difficile la comprensione dell’ironia anche per l’uomo e in particolare per le macchine. In questo lavoro, si propone un’analisi sul ruolo che l’informazione testuale gioca nella percezione e realizzazione dell’ironia nei tweet. Ci si focalizzerà sull’impatto di elementi convenzionali della scrittura digitale, che sembrano rappresentare una sostituzione dei tipici gesti e toni della comunicazione orale, nell’interpretazione figurativa dei messaggi in italiano. Il modello computazionale elaborato è stato usato in un sistema di irony detection, valutato a Sentipolc, Evalita 2016.

متن کاملGestural codas pave the way to the understanding of verbal irony
It is well known that speakers rely on prosodic and gestural features at the time of producing and understanding verbal irony. Yet little research has examined (a) how gestures manifest themselves in spontaneous speech, both during and after ironic utterances; and (b) how the presence of the so-called ‘gestural codas’ (audiovisual cues produced after the ironic utterance) influences irony detec...
متن کاملMental Timeline in Persian Speakers’ Co-speech Gestures based on Lakoff and Johnson’s Conceptual Metaphor Theory
One of the introduced conceptual metaphors is the metaphor of "time as space". Time as an abstract concept is conceptualized by a concrete concept like space. This conceptualization of time is also reflected in co-speech gestures. In this research, we try to find out what dimension and direction the mental timeline has in co-speech gestures and under the influence of which one of the metaphoric...

This paper renewed the representation problem of tone in phonology theory. Accumulating evidence from phonetic researches shows that tones are not abstract autosegmentals. In contrast, stable temporal structures are found regarding tonal alignments to segmental productions. That is, tone gesture is coupled with consonant and vowel gestures in syllable production. This paper described new eviden...
