To this aim, most of the state of the art works exploit the text associated to a social post provided by the user. However, such textual data is typically noisy due to the subjectivity of the user which usually includes text useful to maximize the diffusion of the social post. In this paper we extract and employ an Objective Text description of images automatically extracted from the visual content rather than the classic Subjective Text provided by the users. The proposed method defines a multimodal embedding space based on the contribute of both visual and textual features. The sentiment polarity is then inferred by a supervised Support Vector Machine trained on the representations of the obtained embedding space. Experiments performed on a representative dataset of 47235 labelled samples demonstrate that the exploitation of the proposed Objective Text helps to outperform state-of-the-art for sentiment polarity estimation.}, keywords={data mining;image representation;learning (artificial intelligence);pattern classification;sentiment analysis;social networking (online);support vector machines;textual data;social post;visual features;textual features;sentiment polarity estimation;visual sentiment analysis;positive sentiment;negative sentiment;classic subjective text;objective text description images;multimodal embedding space;support vector machine;Visualization;Feature extraction;Sentiment analysis;Dogs;Flickr;Task analysis;Noise measurement;Visual Sentiment Analysis;Social Media Analysis;Objective Text Description;Multimodal Embedding}, doi={10.1109/CBMI.2018.8516481}, ISSN={}, month={Sept}, url={},}
