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>$
