apertium-tagger --supervised|-s {n} DIC CRP TSX PROB HTAG UNTAG [--debug|-d]

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
