[Mead] need help regarding optimal feature weights

[sravich.c c]

Dear sir,

We are planning to compare our system with MEAD.

We would like to know the optimal values for features
Centroid
Position
QueryTitleCosineNoIDF

A value of QueryTitleCosineNoIDF = 1 for any query seems to generate same
answer  on a particular cluster of documents. Am i doing something wrong?

Our configuration file  is as follows:
********
compression_basis    sentences
compression_absolute    6
feature QueryTitleCosineNoIDF
/mead/bin/feature-scripts/QueryCosineNoIDF.pl  -q t
/mead/data/GA3/GA3.query /mead/data/GA3/docsent
classifier /mead/bin/default-classifier.pl Centroid 1 Position 1
QueryTitleCosineNoIDF 1
reranker i/mead/bin/cst-rerankers/mmr-reranker.pl 0.6 MEAD-cosine enidf
**************
We would like to know optimal values of feature weights for  both news
articles and other general articles.
Please help us as soon as possible.

With regards,
SRAVI
