As the advancement of social platform, media capturing devices, and media processing tools, large volumes of user-generated content or professionally edited content are shared and disseminated on the Web. Internet users can browse, comment, edit, and sometimes creatively re-compose this content to generate new media, giving new insights or interesting applications. A fundamental question, therefore, arises - Why are we attracted to multimedia content and services? How can we make our multimedia content, services, and experiences more attractive? Massive multimedia data shared on social media platforms apparently raise multimedia research challenges and opportunities; however, few research efforts have been put on these interesting and challenging topics. This workshop is intended to provide a forum for researchers and engineers to present their latest innovations and share their experiences on all aspects of attractiveness computing in multimedia.
