On December 1 (Mon.), 2025, at Keio University, we held the 1st Data Collaboration Research Group (SIG-DC: Special Interest Group on Data Collaboration) as part of the JSAI Joint Workshops 2025 (SIGAIs 2025).

Five research presentations were delivered. In the general discussion, presenters and attendees engaged in a lively exchange on co-creation and collaboration in a data-driven society.

We would like to thank everyone who presented and participated.
