Open Master Thesis - Contact a supervisor for more details!

Images are part of political communication online but are a different vocabulary than language. In this sense, images can function as an extension of news framing and influence reader perceptions. This simple tactic is known from the yellow press and online via “clickbait”. In contrast to sentiment dictionaries, a lexicon of sentimental images is not yet common in political research. This thesis compares language-based results of predicting veracity, popularity, and sentiment to a new set of results produced with the presence of sentimental images. The student must start by surveying the state of image data in political science, social science, and CSS. The idea is to offer these fields a dataset that they want to use and cite. The best way to do so is by identifying a stated need or by expanding on suggestions for future work. This should be the main guideline of the thesis. The student will collect biased news from media bias fact-check[1]. Then, the student will apply a zero-shot learning based classifier to predict emojis from the images [Cappallo, 2015] in news articles and measure the effect of using sentimental images on a media bias dataset that he/she will collect.
