IndraTranslation

Indonesian-English Translation inen

inen is a transfer grammar from INDRA (in) to ERG (en) (see LogonTransfer).

Transfer Grammars

inen is in tm folder, along with other transfer grammars, which can be downloaded from the Github.

For INDRA, we cloned the tm folder to grammar folder.

~/grammar$ git clone http://github.com/sanghoun/tm.git

Machine Translation

1. update and compile the source grammar INDRA.

~/ind$ ace -g ace/config.tdl -G ind.dat

2. update and compile the target grammar ERG.

~logon/lingo/erg$ ace -g ace/config.tdl -G erg.dat

3. update and compile the transfer grammar inen.

~/grammar/tm/inen$ ace -g ace/config.tdl -G inen.dat

4. translating by INPUT | PARSING | TRANSFER | GENERATION

$ echo "anjing menggonggong" | ace -g YOUR_INDRA_DIRECTORY/ind.dat | ace -g YOUR_INEN_DIRECTORY/inen.dat | ace -g YOUR_ERG_DIRECTORY/erg.dat -e

Transfer Rules

1. Edit in.vpm under ~/grammar/tm/inen to transfer e.g.:

• the underspecified tense in Indonesian into present tense in English,
• third person (underspecified for number) in Indonesian into third person plural in English,
• perfect aspect in Indonesian into past tense in English.

E.TENSE : TENSE
  tense >> pres

PNG.PERNUM : PERS NUM
  3rd >> 3 pl

E.ASPECT : TENSE
  perf >> past

2. In out.vpm

TENSE : TENSE
  * >> *

PERS : PERS
  * >> *

NUM : NUM
  * >> *

3. In test.mtr, map menggonggong to bark and anjing to dog

bark_mtr := monotonic_mtr &
[ INPUT.RELS < [ PRED "_menggonggong_v_rel" ] >,
  OUTPUT.RELS < +copy+ & [ PRED "_bark_v_1_rel" ] > ].

dog_mtr := monotonic_mtr &
[ INPUT.RELS < [ PRED "_anjing_n_rel" ] >,
  OUTPUT.RELS < +copy+ & [ PRED "_dog_n_1_rel" ] > ].

udef_mtr := monotonic_mtr &
[ INPUT.RELS < [ PRED "exist_q_rel" ] >,
  OUTPUT.RELS < [ PRED udef_q_rel ] > ].

Debugging

If we find a problem in transferring and generating the translation, we should do debugging.

1. Check the want-to-be MRS in the target grammar ERG, save it in a file.

2. Compare with the MRS in the source grammar INDRA and in the transfer grammar inen.

$ echo "anjing menggonggong" | ace -g YOUR_INDRA_DIRECTORY/ind.dat -Tf -vv | less

$ echo "anjing menggonggong" | ace -g YOUR_INDRA_DIRECTORY/ind.dat | ace -g YOUR_INEN_DIRECTORY/inen.dat -Tf -vv | less

3. Edit the grammar(s) or transfer rules
