On August 28, 2026, eight oral presentations from projects involving our lab were presented at the 3rd Meeting of the Special Interest Group on Data Collaboration (SIG-DC), held at the Hikone Campus of Shiga University.

The presentations covered a diverse range of topics, including dataset discovery and similarity assessment, cross-domain data utilization, marine data governance, decentralized data markets, Open Banking, and enterprise data platforms. Through these studies, we discussed how relationships among data, contexts of data use, and data distribution and access environments can be captured and leveraged for discovery, evaluation, and value creation using AI and data analytics technologies.
