The goal of the PIKM workshop series is two-fold: First, we want to give doctoral students an opportunity to present their work in an early state to a global audience. This allows the students to receive feedback from reviewers, from fellow students and from the general CIKM audience. Second, we believe that the general research community, too, benefits from such a workshop: PhD theses are the grassroots of research. They point out new exciting new research avenues and provide fresh perspectives from the next generation researchers.
