NAME

       lt-proc - This application is part of the lexical processing modules and tools ( lttoolbox )

       This tool is part of the apertium machine translation architecture: http://apertium.sf.net.

SYNOPSIS

       lt-proc [ -a | -g | -n | -p | -s | -v | -h ] fst_file [input_file [output_file]]

       lt-proc	[  --analysis  |  --generation	|  --non-marked-gen  | --post-generation | --sao | --version | --help ] fst_file [input_file [out-
       put_file]]

DESCRIPTION

       lt-proc is the application responsible of providing the four lexical processing functionalities

	      o morphological analyser	( option -a )

	      o lexical transfer  ( option -n )

	      o morphological generator  ( option -g )

	      o post-generator	( option -p )

       It accomplishes these tasks by reading binary files containing a compact and efficient representation of dictionaries (a class  of  finite-
       state transducers called augmented letter transducers). These files are generated by lt-comp(1).

       It is worth to mention that some characters (`[', `]', `$', `^', `/', `+') are special chars used for format and encapsulation. They should
       be escaped if they have to be used literally, for instance: `['...`]' are ignored and the format of a linefeed is `^...$'.

OPTIONS

       -a, --analysis
	      Tokenizes the text in surface forms (lexical units as they appear in texts) and delivers, for each surface form, one or more lexical
	      forms consisting of lemma, lexical category and morphological inflection information. Tokenization is not straightforward due to the
	      existence, on the one hand, of contractions, and, on the other hand, of multi-word lexical units. For contractions, the system reads
	      in  a single surface form and delivers the corresponding sequence of lexical forms. Multi-word surface forms are analysed in a left-
	      to-right, longest-match fashion. Multi-word surface forms may be invariable (such as a multi-word  preposition  or  conjunction)	or
	      inflected  (for example, in es, "echaban de menos", "they missed", is a form of the imperfect indicative tense of the verb "echar de
	      menos", "to miss"). Limited support for some kinds of discontinuous multi-word units is also available.  Single-word  surface  forms
	      analysis	produces  output  like the one in these examples: "cantar" -> `^cantar/cantar<vblex><inf>$' or "cantaba" -> `^cantaba/can-
	      tar<vblex><pii><p1><sg>/cantar<vblex><pii><p3><sg>$'.

       -g, --generation
	      Delivers a target-language surface form for each target-language lexical form, by suitably inflecting it.

       -n, --non-marked-gen
	      Morphological generation (like -g) but without unknown word marks (asterisk `*').

       -p, --post-generation
	      Performs orthographical operations such as contractions and apostrophations. The post-generator is usually dormant (just copies  the
	      input  to the output) until a special alarm symbol contained in some target-language surface forms wakes it up to perform a particu-
	      lar string transformation if necessary; then it goes back to sleep.

       -s, --sao
	      Input processing is in orthoepikon (previosuly `sao') annotation system format: http://orthoepikon.sf.net.

       -v, --version
	      Display the version number.

       -h, --help
	      Display this help.
