You might also have a look at the quality package under contrib/
benchmark, as it works w/ trec files, etc. I am not sure what the
similarity parameter is you are referring to, but if I recall (and it
has been a while), in the rel. files the last number is either 1 or 0,
depending on whether your system thinks the document is relevant or
not. Thus, you could do something like score > 0 ? 1 : 0 for
outputting that value, or some variation of that.
If that isn't right, I would dig into some of the TREC papers,
especially the overview paper published each conference, my guess is
one of them will explain it in more detail, or perhaps any docs for
the trec_eval program will.

Hello,
I am using treceval for precision, recall calculation. Treceval
takes Relevance judgments and Result file as an arguments to
calculate the precision, recall. There is a similarity parameter in
the result file.
The score which is calculated by Lucene is equal to that similarity
parameter. Kindly guide me.

Liaqat
