Meeting Recording Pool for RT-05S the Evaluation

Updated: February 11, 2005

The following table summarizes the meetings that will be used to construct the RT-05S evaluation corpus.  They will be contributed by five research organizations.  CMU, ICSI and NIST will contribute meetings to the '05 evaluation that are similar in nature to the meetings used in the '04 evaluation.  The AMI and CHIL programs are new data contributors to the evaluation.   The AMI program will contribute conference room meetings, while the CHIL program will contribute lecture room meetings. 

The table below describes the meetings contributed by each organization.  This information, some of which is not legal side information for a system, is intended not to describe the makeup of the evaluation corpus, but rather a complete accounting of all the sensors collected for each meeting.  Some of the sensors may not be published in the evaluation corpus.
