About the Event

We analyze collective discourse, a collective human behavior in content generation, and show that it exhibits diversity, a property of general collective systems. Using extensive analysis, we propose a novel paradigm for designing summary generation systems that reflect the diversity of perspectives seen in real-life collective summarization. As a concrete example of collective discourse, we will discuss citations to scholarly work. We will show how they contain important information that convey the key features and basic underpinnings of a particular field, early and late developments, important contributions, and basic definitions and examples that enable rapid understanding of a field by non-experts. We will finally present C-LexRank, a system that exploits scientific collective discourse to produce automatically generated, readily consumable technical surveys.
