NAME

nat-create - Command line tool to create NATools Corpora Objects

SYNOPSIS

   nat-create <file1.nat> <file2.nat>

   nat-create -tmx <file.tmx>

DESCRIPTION

This is the basic command used to create a NATools Corpora Object from the command line.

A NATools Corpora Object is a ditectory with:

• the configuration file ("nat.cnf" - metadata information)

• the corpus

• the corpus indexes

• the probabilistic translation dictionaries ("source-target.dmp", "target-source.dmp")

• the (bi,tri,tetra)grams databases ("source.ngrams", "target.ngrams")

Known Switches

tokenize

The -tokenize flag can be used to force NATools to tokenize the texts. Note that at the moment a Portuguese tokenizer is used for all languages. This might change in the future.

id

The -id=name flag can be used to force NATools Corpora name. By default the name is read interactively.

q

The -q flag can be used to force quiet mode. In thic case, the name is extracted from the file-names.

lang

The -lang=PT..EN flag can be used to force languages.

ngrams

The -ngrams flag can be set to force NATools to create ngrams indexes.

noEM

The -noEM flag is used to bypass the EM-Algorithm (useful for debug purposes, mainly).

ipfp

The -ipfp flag is mutually exclusive with -noEM, -samplea and -sampleb. It defines that the EM-Algorithm to be used is the IPFP one. Optional numeric argument is the number of iterations. Defaults to 5.

samplea

The -samplea flag is mutually exclusive with -noEM, -ipfp and -sampleb. It defines that the EM-Algorithm to be used is the Sample A one. Optional numeric argument is the number of iterations. Defaults to 10.

sampleb

The -sampleb flag is mutually exclusive with -noEM, -ipfp and -samplea. It defines that the EM-Algorithm to be used is the Sample B one. Optional numeric argument is the number of iterations. Defaults to 10.
