Systematization of Knowledge Papers

Following the success of the previous years’ conferences, we are also soliciting papers focused on systematization of knowledge (SoK). The goal of this call is to encourage work that evaluates, systematizes, and contextualizes existing knowledge. These papers can provide a high value to our community but may not be accepted because of a lack of novel research contributions. Suitable papers include survey papers that provide useful perspectives on major research areas, papers that support or challenge long-held beliefs with compelling evidence, or papers that provide an extensive and realistic evaluation of competing approaches to solving specific problems. Submissions are encouraged to analyze the current research landscape: identify areas that have enjoyed much research attention, point out open areas with unsolved challenges, and present a prioritization that can guide researchers to make progress on solving important challenges. Submissions must be distinguished by a checkbox on the submission form. In addition, the paper title must have the prefix “SoK:”. They will be reviewed by the full PC and held to the same standards as traditional research papers, except instead of emphasizing novel research contributions the emphasis will be on value to the community. Accepted papers will be presented at the symposium and included in the proceedings.
