About the Conference

WSDM (pronounced “wisdom”) is one of the premier conferences on web-inspired research involving search and data mining. WSDM is a highly selective conference that includes invited talks, as well as refereed full papers. WSDM publishes original, high-quality papers related to search and data mining on the Web and the Social Web, with an emphasis on practical yet principled novel models of search and data mining, algorithm design and analysis, economic implications, and in-depth experimental analysis of accuracy and performance. The 19th ACM International WSDM Conference will take place in Boise, Idaho, USA, from February 22 to February 26, 2026.
