A .lexc file defines how morphemes in the language are joined together, morphotactics.
Contents |
This page describes some how lttoolbox and HFST's lexc are similar, so that people more familiar with one can get to grips more easily with the other.
Terminology[edit]
| lttoolbox | lexc | Notes |
|---|---|---|
| Paradigm | Continuation lexicon | So each time you see LEXICON foo, think <pardef n="foo"/>
|
| Section | Root lexicon | |
| Left | Up | Both left and upper correspond to surface form |
| Right | Down | Corresponds to lexical form |
| Symbol | Multichar symbol | Sequences of one or more symbol which are treated as one symbol |
Example[edit]
lttoolbox[edit]
<dictionary>
<sdefs>
<sdef n="n"/>
<sdef n="pl"/>
<sdef n="sg"/>
</sdefs>
<pardefs>
<pardef n="RegNounInfl">
<e><p><l/><r><s n="n"/><s n="sg"/></r></p></e>
<e><p><l>s</l><r><s n="n"/><s n="pl"/></r></p></e>
</pardef>
</pardefs>
<section id="Root" type="standard">
<e lm="cat"><i>cat</i><par n="RegNounInfl"/></e> <!-- A noun -->
</section>
</dictionary>
And to compile and use this dictionary:
$ lt-comp lr test.dix test.bin Root@standard 7 7 $ echo "cat" | lt-proc test.bin ^cat/cat<n><sg>$ $ echo "cats" | lt-proc test.bin ^cats/cat<n><pl>$
lexc[edit]
See also: Apertium-specific conventions for lexc
Multichar_Symbols %<n%> %<pl%> %<sg%> LEXICON Root NounRoot ; LEXICON NounRoot cat RegNounInfl ; ! A noun LEXICON RegNounInfl %<n%>%<sg%>: # ; %<n%>%<pl%>:s # ;
And to compile and use this dictionary:
$ hfst-lexc test.lexc -o test.gen.hfst $ hfst-invert -i test.gen.hfst -o test.mor.hfst $ echo "cat" | hfst-lookup test.mor.hfst cat cat<n><sg> $ echo "cats" | hfst-lookup test.mor.hfst cats cat<n><pl>
