The Evaluation of Technologies for Uncertainty Reasoning Working Group (ETURWG) is an official working group of the International Society for Information Fusion (ISIF), which was formalized in July 2011. The group provides a forum for its members to collectively address a common need for the ISIF community, coordinate with researchers in the area, and evaluate techniques for assessing, managing, and reducing uncertainty. The main aspects involved are:

1. To establish features required for any quantitative uncertainty representation to support the exchange of soft and hard information in a net-centric environment;
2. to develop a set of use cases involving information exchange and fusion requiring reasoning and inference under uncertainty; and
3. to define evaluation criteria supporting unbiased comparisons among different approaches applied to the use cases.
