Professionals are invited to submit proposals for Special Sessions. Special Sessions should focus on a topic which is of particular interest to the FDL audience. Special Sessions consist of two to four invited talks. Speakers are requested to either submit a one page abstract of their presentation, or to submit a short or full paper that goes through the regular review and publication process. Potential organizers of a Special Session must submit a brief proposal (no more than two pages) which describes the topic, the intended audience, as well as a list of possible speakers to fdl2020@easychair.org
