This version of MUC_scorer uses a scoring metric for Named Entity
tagging of automated speech recognition (ASR) output developed 
at MITRE, and originally implemented in MITRE's "Mscore" software.
The license for Mscore is below.

The algorithm for scoring the coreference task was also developed at the
MITRE Corporation (see "A Model-Theoretic Coreference Scoring Scheme"
in the MUC 6 proceedings).  It was originally implemented in lisp by
John Burger at MITRE.  The license for that software is after the Mscore
license.
