HSoC2026: HICSS Symposium on Computational Social Science (@ HICSS2026)


Symposium on Computational Socila Science (@HICSS2026)

Modern social science is facing a paradigm shift due to the development of computer and Internet technologies. Human behavior and social phenomena are possible to be quantified by big data digitally tracing online activities and mobility records at a granular level. In some cases, big data can be analyzed using technologies evolving in the natural sciences, such as physics, chemistry, and biology. Experimental data and multiple results from theoretical and computational simulations complement them. Both theoretically and analytically grounded insights may open new doors of computational social sciences.

From this perspective, we will hold a mini-symposium on issues related to computational social science. The scope of the mini-symposium includes, but is not limited to, big data applications, big data collection and use, an integrated framework for theory, simulation, statistics, and experiments.

The Society for CSSJ is actively involved in hosting international conferences as a research outreach activity, and this year we will hold a “Mini-Symposium on Computational Social Science” at HICSS in January 2026. The purpose of this mini-symposium is to introduce outstanding papers presented at the 4th annual conference of CSSJ held at University of Tsukuba in 2025 as invited papers to the world, thereby contributing to Japan’s presence.
