name: lat_to_nbest
synopsis: lat_to_nbest [options] 

description:  
this is the isip lattice to nbest hypotheses generation utility

all input to the utility is provided via a parameter file.

Note that the lexicon must follow a specific order of words.
This order is --- !SENT_END, then !SENT_START, followed by !NET_START,
and these followed by all words sorted in alphabetical order. In case
dynamic LMs are not used in your application, !NET_START need not
appear in the lexicon

arguments:

  -p params_file	: parameters file
  -help                 : this file

examples:

lat_to_nbest -p params.text

an example parameter file:

   # parameters file for the isip lat_to_nbest
   #
   
   # define input lattice list
   #
   input_lattice_list = test_lattice.list
   
   # define output nbest list
   #	
   output_nbest_list = test_nbest.list
   
   # define lexicon file
   #
   lexicon_file = lexicon.text
   
   # define n-best paths to preserve (N > 0)
   # - nbest_paths defines the number of final sentence hypotheses to output
   #
   nbest_paths = 10
   
   # define the pruning parameters for the nbest list
   # - max_paths defines the maximum number of paths allowed at any
   #   time instance that will be used to determine the nbest paths
   # - nbest_beam defines the beam pruning threshold
   nbest_max_paths = 50
   nbest_beam = 100
