Perception of Visual Sentiment: From Experimental Psychology to Computational Modeling

Mohan Kankanhalli

School of Computing, National University of Singapore, Singapore

ABSTRACT  A picture is worth a thousand words. Visual representation is one of the dominant forms of social media. The emotions that viewers feel when observing a visual content is often referred to as the content’s visual sentiment. Analysis of visual sentiment has become increasingly important due to the huge volume of online visual data generated by users of social media. Automatic assessment of visual sentiment has many applications, such as monitoring the mood of the population in social media platforms (e.g., Twitter, Facebook), facilitating advertising, and understanding user behavior. However, in contrast to the extensive research on predicting textual sentiment, relatively less work has been done on sentiment analysis of visual content. In contrast to textual sentiment, visual sentiment is more subjective and implicit. There exists significant semantic gap between high-level visual perception and low-level computational attributes.

In this talk, we argue that these challenges can be addressed by combining the findings from the psychology and cognitive science domain. We will show that a deeper understanding of human perception helps create better computational models. To support that thesis, we will first briefly overview our human-centric research framework, which focuses on applying the paradigms and methodologies from experimental psychology to computer science: First, we collect visual data with human perception through online or lab-controlled psychophysics studies. Then we use inferential statistics to analyze the psychophysics data and model human perception empirically. We then design computational models based on the empirical findings.

We will present three works on visual sentiment in our lab, guided by this research framework. In our first work, we aim to understand human visual perception in a holistic way. We first fuse various partially overlapping datasets with human emotion. We build an empirical model of human visual perception, which suggests that six different types of visual perception (i.e., familiarity, aesthetics, dynamics, oddness, naturalness, spaciousness) significantly contribute to human’s positive sentiment (i.e., liking) of a visual scene.

In our second work, we investigate the relation between human attention and visual sentiment. We build a unique emotional eye fixation dataset with object and scene-level human annotations, and exploit comprehensively how human attention is affected by emotional properties of images. Further, we train a deep convolutional neural network for human attention prediction on our dataset. Results demonstrate that efficient encoding of image sentiment information helps boost its performance.

Our third work explores how human attention influences visual sentiment. We experimentally disentangle effects of focal information and contextual information on human emotional reactions, then we incorporate related insights into computational models. On two benchmark datasets, the proposed computational models demonstrate superior performance compared to the state-of-the-art methods on visual sentiment prediction.

We will end with future research direction on visual sentiment analysis. Our studies highlight the importance of understanding human cognition for interpreting the latent sentiments behind visual scenes.
