ok here's a few lines from the file i'm searching (its a wordnet file
that holds different senses of words)

concavity%1:07:00:: 05070032 2 0
concavity%1:25:00:: 13864965 1 0
concavo-concave%5:00:00:concave:00 00536008 1 0
concavo-convex%5:00:00:concave:00 00536416 1 0
conceal%2:39:00:: 02146790 2 1
conceal%2:39:01:: 02144835 1 8
concealed%3:00:00:: 02088404 2 1
concealed%5:00:00:invisible:00 02517817 1 2
concealing%1:04:00:: 01048912 1 0
concealing%3:00:00:: 02091020 1 0


i need to search for the first part (e.g. conceal%2:39:00::) and
return the second last number (eg. 2). (getting the sense from the
sense key, if you know wordnet)

i have 1400 words, the wordnet file will never change. i'm unlikely to
need to scale up much past 1400.

here's my code: (senseKey is eg "conceal%2:39:00::")

lines=File.readlines("/usr/local/WordNet-3.0/dict/index.sense")

#gets a sysnet number from a sense key
def getSense(senseKey,lines)
  for line in lines
    if line.index(senseKey)==0
      words=line.split(" ")
      return words[-2]
    end
  end
end


thanks again!
