Problem with Arabic transliteration

[ronaldtse]

From @gilgameshjw 's run using GNDB data.

• ara is the source
• ara_diacri is the diacriticized Arabic produced with rababa
• DEST_FULL_NAME_RO is the manual transliteration provided in GNDB
• ara_latinised is the output of Interscript

93	أرض الرجوم	أَرْضِ الرُّجُومِ	arḍi al-rrujūmi	93	arḑ ar rujūm	0.500000

Clearly there is some difference in certain entries, if you look at 91 and 93, the transliteration system is different.

@gilgameshjw can you help confirm:

• which GNDB dataset are you using?
• which transliteration system are you using?

Method to easily reproduce this output? 😉 Thanks!

Analysis and Answers:

• GNDB dataset?
  I am using :
  GNDBdataset/ara_Arab2Latn_ALA_1997.csv & GNDBdataset/ara_Arab2Latn_BGN_1956.csv

• transliteration systems:

interscript ../GNDB/ara_ALA_1997_dia.txt --system=alalc-ara-Arab-Latn-1997 --output=../GNDB/ara_ALA_1997_dia_2_lat.txt
interscript ../GNDB/ara_BGN_1956_dia.txt --system=bgnpcgn-ara-Arab-Latn-1956 --output=../GNDB/ara_BGN_1

• reproduce output:
  We attach the jupyter analysis (in txt format because .ipynb and .py not allowed) that has some of the commands we
  ran, in part under /python in rababa.
  We also added analysis files.

analysis_ALA_1997.csv
analysis_BGN_1956.csv

Hello, Here’s what am thinking I’ll take the file jair created, and comment on every possible entry with error Whether it’s a mapping issue or a pointing issue To start with 1-I have a strong feeling the map used is not the best match for this dataset, as I can see in the examples provided by Ronald the sun letters rules are applied to the results, while the map used, doesn’t have sun letters 2-I can see that the output contains the final letter diacritic, which might/might not be omitted, based on the sentence Almost similar to how last letters in french are omitted sometimes in pronunciation — this can be modified in the maps, as a rule to optionally omit the three main diacritics (fatha-damma-kasragh) if they’re on the last letters of the word

@AhMohsen46 @ronaldtse mentionned on skype (which you might not be able to access) that possibly, the GNDB diacritized data itself could be bad.

Maybe we can investigate on that?

[ronaldtse]

@AhMohsen46 as mentioned by @gilgameshjw , the GNDB datasets may contain mis-tagged transliterations. e.g. most of the Arabic transliterations should actually be BGN/PCGN, but some may be mis-tagged as ALA-LC.

Part of our work here is also find a good way to detect mis-tagged transliteration. The new "detect" feature in Interscript should help.
