Particularly, understanding online users' opinions or sentiments is a fundamental task that can benefit many applications, such as political campaigning and commercial marketing. We present a few recent advances in social multimedia sentiment analysis. Specifically, this tutorial consists of three parts. The first part is on visual sentiment analysis. We will introduce the task of visual sentiment, its main challenges, and the state-of-the-art approaches. We will include several representative approaches to manually designing visual features for this task as well as some approaches using deep neural networks. The second part is on building multimedia sentiment analysis datasets. We will introduce the challenges, the solutions in the construction of different large-scale datasets for sentiment analysis. The final part is mainly on multimodality model for sentiment analysis. We will introduce some recent research projects on multimodality designing and learning. In addition, we will also share some applications of sentiment analysis, as well as thoughts on current challenges and future directions.
