DESCRIPTION

       apertium-tagger is the application responsible  for  the  apertium  part-of-speech  tagger
       training  or  tagging, depending on the calling options.  This command only reads from the
       standard input if the option --tagger or -g is used.

OPTIONS

       -t {n}, --train {n}
              Initializes parameters through the Kupiec's method (unsupervised), then performs  n
              iterations of the Baum-Welch training algorithm (unsupervised).

       -s {n}, --supervised {n}
              Initializes  parameters against a hand-tagged text (supervised) through the maximum
              likelihood estimate method, then performs n iterations of the  Baum-Welch  training
              algorithm (unsupervised)

       -r {n}, --retrain {n}
              Retrains the model with n additional Baum-Welch iterations (unsupervised).

       -g, --tagger
              Tags input text by means of Viterbi algorithm.

       -p, --show-superficial
              Prints  the  superficial form of the word along side the lexical form in the output
              stream.

       -f, --first
              Used if conjuntion with -g (--tagger) makes the tagger to give all lexical forms of
              each word, being the choosen one in the first place (after the lemma)

       -d, --debug
              Print error (if any) or debug messages while operating.

       -m, --mark
              Mark disambiguated words.

       -h, --help
              Display a help message.

FILES

       These are the kinds of files used with each option:

       DIC Full expanded dictionary file

       CRP Training text corpus file

       TSX Tagger specification file, in XML format

       PROB Tagger data file, built in the training and used while tagging

       HTAG Hand-tagged text corpus

       UNTAG Untagged text corpus, morphological analysis of HTAG corpus to use both jointly with
       -s option

       INPUT Input file, stdin by default

       OUTPUT Output file, stdout by default
