Papers for a special session should be submitted to the special session track instead of the main conference in the DSAA’2020 submission system.
Special session papers strictly follow the same specifications, requirements and policies as the main conference submissions in terms of the paper submission deadline, notification deadline, paper formatting and length, and important policies. The paper length allowed for the papers is a maximum of ten (10) pages. The format for the papers is the standard 2-column U.S. letter style IEEE Conference template.

Top-quality papers accepted at the DSAA2020 conference will be selected for extension and invited to the special issues of the International Journal of Data Science and Analytics (JDSA, Springer) and some other journals DSAA2020 is working on.
