Publication
ALL accepted iiWAS2021 papers will be published by ACM International Conference Proceedings Series (to be confirmed) and the supplemental proceedings (ISBN: pending) which will be archived in the ACM Digital Library, and indexed by DBLP, Ei Compendex, Scopus and submitted to be reviewed by Thomson Reuters Conference Proceedings Citation Index (ISI Web of Science). Selected high-quality papers will be invited to be published, after revision and extension, in special issues of international journals.

Scope
Data and information are crucial in providing evidence based decision making in many aspect of human activities, as an individual or as a group. The way information and communication technology are used to collect, process, analysis and store data has always evolves. New techniques are invented, existing techniques are improved and old techniques are integrated to the new. Each of these provided some challenges and opportunities to our research community in finding the best way to meet these challenges. iiWAS provides research community with the opportunity to share and discuss their ideas.

Prior to 2020, iiWAS has been held in Munich (2019), Yogyakarta (2018), Salzburg (2017), Singapore (2016), Brussels (2015), Hanoi (2014), Vienna (2013), Bali (2012), Ho Chi Minh City (2011), Paris (2010), Kuala Lumpur (2009), and Linz (2008). Last year, iiWAS2020 conference was held as a virtual conference. Again this year, iiWAS2021 will be held virtually with the host managing the conference from the campus of JKU in Linz, Austria.

Submissions
iiWAS accepted four different types of contributions:
- Original theoretical work: The contributions are expected to show original work that provide foundations to further progress research in the area. Rigorous proofs and/or performance measurements are expected for this type of contribution.
- Real life case study: The contributions are expected to show a real life case study of an adopted concept and technology. The analysis of the case study should provide an original insight and findings, backing up by data collected from experiments and/or observation.
- Experimental work: The contributions are expected to show reporting of rigorous comparative experiments of existing algorithms/systems to provide insight to the current state of the art in a research domain.
- Lessons learnt reports: The contributions are expected to show lessons learnt from adoption of complex technology integration or implementation.

Submission Guidelines
Papers must be submitted electronically in PDF through the conference website. Submitted papers must not substantially overlap with papers that have been published or that are simultaneously submitted to a journal or a conference with proceedings.
Submitted papers will be subject to stringent peer review by at least three members of the international program committee and carefully evaluated based on originality, significance, technical soundness, and clarity of exposition. Accepted papers will appear in the conference proceedings to be published by ACM (to be confirmed).

Format requirements for submissions of papers are:

Maximum 12 pages, including the abstract (no more than 150 words), all figures and references for Full Technical papers.
Maximum 6 pages, including the abstract (no more than 150 words), all figures and references for Short Position Papers.
All submissions should be formatted according to ACM guidelines (https://www.acm.org/publications/proceedings-template)
Submissions must be entered into the Submission System (https://www.easychair.org/conferences/?conf=iiwas2021)
Awards
iiWAS2021 best paper awards and student paper awards will be conferred on the authors at the conference.
