TL;DR
This paper investigates the factors influencing image virality on social media, introducing new datasets and methods to predict virality using visual and semantic features, outperforming human predictions in some cases.
Contribution
It introduces three new Reddit image datasets, defines a virality score, and develops classifiers using high-level features and semantic attributes to predict image virality.
Findings
High-level features are crucial for virality prediction.
Semantic attributes can predict relative virality with 68.10% accuracy.
Computers outperform humans in predicting image virality based on visual attributes.
Abstract
Virality of online content on social networking websites is an important but esoteric phenomenon often studied in fields like marketing, psychology and data mining. In this paper we study viral images from a computer vision perspective. We introduce three new image datasets from Reddit, and define a virality score using Reddit metadata. We train classifiers with state-of-the-art image features to predict virality of individual images, relative virality in pairs of images, and the dominant topic of a viral image. We also compare machine performance to human performance on these tasks. We find that computers perform poorly with low level features, and high level information is critical for predicting virality. We encode semantic information through relative attributes. We identify the 5 key visual attributes that correlate with virality. We create an attribute-based characterization of…
