Abstract

With an exponential growth in social multimedia contents online, there is an increasing importance of understanding why and how some contents are perceived as persuasive while others are ignored. This paper outlines my research goals in understanding human perception of persuasiveness in social multimedia contents, which involve studying how different communication modalities influence our perception and identifying key verbal and nonverbal behaviors that eventually lead us to believe someone is convincing and influential. For any research involving in-depth human behavior analysis, it is imperative to obtain accurate annotations of human behaviors at the micro-level. In addition to investigating persuasiveness, this work will also provide to the research community convenient web-based annotation tools, effective procedures for obtaining high-quality annotations with crowdsourcing, and evaluation metrics to fairly and accurately measure the quality and agreement of micro-level behavior annotations.
