SSTD 2021 solicits submissions in four tracks.

1. RESEARCH TRACK

Authors are invited to submit long research papers that present original research contributions. The selection criteria include quality, novelty, correctness, and relevance to SSTD. Authors are also invited to submit short research papers that discuss exciting new work that is not yet mature enough for a long paper. In particular, novel but significant proposals will be considered for acceptance to this category despite not having gone through sufficient experimental validation or lacking strong theoretical foundation.

2. DEMO TRACK

Authors are invited to submit demo papers, describing demonstrations of systems, developed or under development. The selection criteria for the demonstration proposals include: the novelty, the technical advances and challenges, and the overall practical attractiveness of the demonstrated system.

3. INDUSTRY TRACK

Authors are invited to submit industry papers that describe original experiences, challenges, systems and applications in industry. For each industry paper, at least one author should have a non-academic affiliation.

4. VISION TRACK

Authors are invited to submit vision papers that describe revolutionary ideas that are likely to guide research in the near future, challenge existing assumptions prevalent in the research community, or identify novel applications and technology trends that create new research challenges.
