There were six papers in the session of Probabilistic IR Models and two of them were from us. The idea about uncertainty of document ranking and portfolio theory have well been received in the conference. The feedback is positive. One of the conference notes can be found at http://miksa.ils.unc.edu/~wke/wordpress/?p=152 written by Weimao Ke.
