This directory contains the results of the different classifiers
for the second baseNP recognition tasks described on

   http://lcg-www.uia.ac.be/~erikt/npcombi/

The files have been divided in four groups:

02ca.*: results for tune data in closeb representation
02ob.*: results for test data in closeb representation
02ca.*: results for tune data in openb representation
02ob.*: results for test data in openb representation

The tune data consists of the final 10% of the RM95 training data.
The test data consist of section 20 of the WSJ corpus. The suffix
of each file is the name of the classifier that produced the results.

The files repr.*.* contain the results of the experiments which have 
been performed with different output representations. Each of these
files contains five columns: the results for the representations
iob1, iob2, ioe1, ioe2 and o+c. (These files are currently not
available).

These results have been put forward by the following people:

allis:  Herve Dejean, University of Tuebingen
c5:     Walter Daelemans, University of Antwerp
igtree: Erik Tjong Kim Sang, University of Antwerp
maxent: Rob Koeling, SRI Cambridge
mbl:    Erik Tjong Kim Sang
mbsl:   Yuval Krymolowski (Bar-Ilan University)
snow:   Vasin Punyakanok (Illinois)
tbl:    generated by Erik Tjong Kim Sang with the baseNP software
        described in Ramshaw & Marcus 1995

The best combination results for the test data can be found in the files
result.02ob and result.01cb.2Both were generated by using majority voting
on the best 5 classifiers. The combined results of open and close 
brackets is stored in result.iob1.
