Workshop Overview

WDDD provides the computer systems research community a forum for work that validates or duplicates earlier results; deconstructs prior findings by providing greater, in-depth insight into causal relationships or correlations; or debunks earlier findings by describing precisely how and why proposed techniques fail where earlier successes were claimed, or succeed where failure was reported.

Traditionally, computer systems research conferences have focused almost exclusively on novelty and performance, neglecting an abundance of interesting work that lacks one or both of these attributes. A significant part of research--in fact, the backbone of the scientific method--involves independent validation of existing work and the exploration of strange ideas that never pan out. This workshop provides a venue for disseminating such work in our community. Published validation experiments strengthen existing work, while thorough comparisons provide new dimensions and perspectives. Studies that refute or correct existing work also strengthen the research community, by ensuring that published material is technically correct and has sound assumptions. Publishing negative or strange or unexpected results will allow future researchers to learn the hard lessons of others, without repeating their effort.

This workshop will set a high scientific standard for such experiments, and will require insightful analysis to justify all conclusions. The workshop will favor submissions that provide meaningful insights, and identify underlying root causes for the failure or success of the investigated technique. Acceptable work must thoroughly investigate and communicate why the proposed technique performs as the results indicate. WDDD has a unique tradition of asking the original paper authors to provide a follow-up comment after the WDDD paper has been presented, where appropriate. The follow-up comment may take the form of a rebuttal or additional insight from the original authors.

Submission Topics
  • Independent validation of earlier results with meaningful analysis
  • In-depth analysis and sensitivity studies that provide further insight into earlier findings, or identify key parameters or assumptions that affect the results
  • Studies that refute earlier findings, with clear justification and explanation
  • Negative results for ideas that intuitively make sense and should work, along with explanations for why they do not
  • Validation/refutation of controversial advertising claims by industrial competitors
