9th International Workshop on Uncertainty Reasoning for the Semantic Web

Organizing committee


Effective methods for reasoning under uncertainty are vital for realizing many aspects of the Semantic Web vision, but the ability of current-generation web technology to handle uncertainty is limited. Demand is growing for uncertainty reasoning technology among Semantic Web researchers and developers. This surge of interest creates a unique opening to bring together two communities with a clear commonality of interest but little history of interaction. By capitalizing on this opportunity, URSW aims to spark dramatic progress toward realizing the Semantic Web vision. The workshop features open discussion topics relevant to the general subject of uncertainty in the Semantic Web.
