چکیده

English. In the literature, subjectivity, polarity and irony detection have been often considered as independent tasks. However, since there are multiple ties between them, they should be jointly addressed. In this paper we propose a hierarchical system, where the classifiers of each layer are built upon an ensemble approach known as Bayesian Model Averaging. Italiano. In letteratura, le classificazioni di soggettività, polarità e ironia sono state spesso affrontate come task indipendenti. Tuttavia, dal momento che esistono tra loro diversi legami impliciti, tali task dovrebbero essere affrontati congiuntamente. In questo lavoro proponiamo un sistema gerarchico, dove i classificatori di ogni layer sono costruiti ricorrendo ad un approccio di ensemble learning noto come Bayesian Model Averaging.

Polarity Contrast for the Detection of Verbal Irony

In this paper, we propose two metrics capable of modeling forms of polarity contrast: polarity divergence and polarity dimorphism. To explore their potential usefulness to the detection of verbal irony and sentiment polarity, we performed an exploratory text analysis on a corpus of figurative tweets annotated by sentiment. The results of a text analysis show that, employing two different types ...
