Freeling

From Apertium

Freeling is a suite of language processing tools, including a tokeniser, sentence splitter, morphological analyser, chunker and dependency parser. Much of this is also done in lttoolbox and apertium, but in some cases data or tools from Freeling could be useful.

Tools

There are some scripts in apertium SVN (module apertium-tools/freeling) for converting between apertium formats and Freeling formats.

  • dix-to-maco.py -- Convert between an lttoolbox expanded dictionary and a Freeling 'maco' format full-form list.
  • tagger-to-parole.py -- Convert between the output of apertium-tagger to Freeling style tagged output.

Both scripts require a file with correspondences between apertium tags and PAROLE style tags.

Example

$ echo "Bro gozh ma zadoù" | lt-proc br-fr.automorf.bin  | cg-proc br-fr.rlx.bin  | apertium-tagger -p -g br-fr.prob  
^Bro/Bro<n><f><sg>$ ^gozh/kozh<adj><mf><sp>$ ^ma/ma<det><pos><mf><sp>$ ^zadoù/tad<n><m><pl>$

$ echo "Bro gozh ma zadoù" | lt-proc br-fr.automorf.bin  | cg-proc br-fr.rlx.bin  | apertium-tagger -p -g br-fr.prob  | tagger-to-freeling.py parole-tags.txt
