Thus, Aspect-Sentiment Analysis (JMASA) task, aiming to jointly extract the aspect terms and their corre-sponding sentiments. For example, given the text-image pair in Table.1, the goal of JMASA is to identify all the aspect-sentiment pairs, i.e., (Sergio Ramos, Positive) and (UCL, Neutral). Most of the aforementioned studies to MABSAnecessarily cover the sentiment expressed by the author towards a specific entity. To address this gap, we introduce PerSenT, a crowdsourced dataset of sentiment annotations on news articles about people. For each article, annotators judge what the author’s sentiment is towards the main (target) entity of the article. Sentiment Analysis in Social Networks. Morgan Kaufmann, S. 4.

While the latter deals with the semantics of a sentence as a whole, the former is concerned with finding which word that sentiment refers to. We briefly describe them in this section. 3.1 Aspect ExtractionIn aspect-level sentiment classification (ASC), it is prevalent to equip dominant neural mod-els with attention mechanisms, for the sake of acquiring the importance of each context word on the given aspect. However, such a mecha-nism tends to excessively focus on a few fre-quent words with sentiment polarities, while ignoring infrequent ones.we can also do sentiment analysis.
