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 iter-
	      ations 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

BUGS

       Lots of...lurking in the dark and waiting for you!
