چکیده

English. In the domain of Natural Language Processing (NLP), the interest in figurative language is enhanced, especially in the last few years, thanks to the amount of linguistic data provided by web and social networks. Figurative language provides a non-literary sense to the words, thus the utterances require several interpretations disclosing the play of signification. In order to individuate different meaning levels in case of ironic texts detection, it is necessary a computational model appropriated to the complexity of rhetorical artifice. In this paper we describe our rulebased system of irony detection as it has been presented to the SENTIPOLC task of EVALITA 2016, where we ranked third on twelve participants. Italiano. Nell’ambito del Natural Language Processing (NLP) l’interesse per il linguaggio figurativo è particolarmente aumentato negli ultimi anni, grazie alla quantità d’informazione linguistica messa a disposizione dal web e dai social network. Il linguaggio figurativo conferisce alle parole un senso che va oltre quello letterale, pertanto gli enunciati richiedono interpretazioni plurivoche che possano svelare i giochi di significato del discorso. Nel caso specifico del riconoscimento automatico di un testo ironico, infatti, determinare la presenza di diversi gradi di significazione esige un modello computazionale adeguato alla complessità dell’artificio retorico. In questo articolo descriviamo il nostro sistema “rule-based” dedito al riconoscimento dell’ironia che ha partecipato al task SENTIPOLC di EVALITA 2016, nel quale ci siamo classificati terzi su dodici partecipanti.
