An affective lexicon is a database of words (or word senses, phrases, or other kinds of lexical items) where each item is classified according to its content in terms of subjectivity, polarity (positive or negative), capability of evoking specific emotions and so on. Such resources are used to build automatic systems that analyze natural language (for example, from websites or social media), and “read” the sentiment expressed in the text. This activity is called Sentiment Analysis (or Opinion Mining) and it is gaining more and more attention from the scientific communities as well as industry, because it can answer questions like “are customers happy with product X?” or “what type of people approve policy Y?”. Italian is a somewhat poorly represented language in the panorama of language resources. This is true for affective lexica too, but thanks to a vibrant community, things are rapidly changing. We conducted a quick survey, asking the members of AILC about affective lexica for Italian. The results of the survey are summarized in the list below. Some of them are lexica, some are other kinds of resources and methods, in the Italian language or otherwise linked to the Italian NLP community.
