Anubadok is an open source English to Bengali MT system developed by G M Hossain, currently in experimental stage.

The program is licensed under GPL. Its accessible from here.

Inflection Rules (BnSondhi.pm)

Legend

  • C Consonant
  • V Vowel
  • _ Any Letter
  • K Kar (Short form of Vowel)
  • G General Rule - The consonants and vowels in the example are exchangeable with any other consonants and vowels
  • S Special Rule - The consonants and vowels in the example are NOT exchangeable with any other consonants and vowels
  • H Hasanth - The joiner, e.g. ঙ+্+গ = ঙ্গ, as in মঙ্গল

__CC means the last two consonants of a word, and CV__ means the first letter of this word is consonant followed by a vowel

Rules

Verb Rules (Applies if the length of the first word is >= 3, rules are not exclusive e.g. one word can qualify for multiple rules)
  • G (C+ো+C)+(তে) = (C+ু+C+তে) e.g. খোল + তে = খুলতে
  • G (া+C+া) + (তে) = (া+C+া+তে) e.g. পাঠা + তে = পাঠাতে
  • G (C+ি)/(C+ে) + (ে+র)্(া+র) = (C+ে+ও+য়+া+র) e.g. নি + ের = নেওয়ার, নে + ার = নেওয়ার
  • G (C+া) + (তে) = (C+ে+তে) e.g. পা + তে = পেতে
  • G (C+ে) + (তে) = (C+ি+তে) e.g. দে + তে = দিতে
  • G (C+C) + (ে+র) = (C+C+া+র) e.g. কর + ের = করার
  • G (__K1) + (K2__) = (__K1__) [needs review]
Preposition Rules

(Applies if the length of the first word is >= 2, rules are not exclusive e.g. one word can qualify for multiple rules)

  • G (ল+ে+C) -> (ল+ি+C) e.g. লেখ -> লিখ
  • G (এ+ই) + (টা) = (এটি) e.g. এই + টি = এটি
  • S (_+ক+ে) + (ে+র) = (_+র) e.g. আমাকে + ের = আমার
  • G (C+C) + (ৈ+র) = (C+C+া+র) e.g. কর + এর = করার
  • G (C/V/H/K + C) + (তে) = (C/V/H/K + C + ে) [needs review]
  • S (ং) + (ে+র) = (ং+এ+র) e.g. সং + ের = সংএর
  • G (__K1) + (K2__) = (__K1__) [needs review]
Main Rules

(Applies if the length of the first word is >= 2, rules are not exclusive e.g. one word can qualify for multiple rules)

  • G (K+C) + (তে) = (K+C+ে) e.g. মার + তে = মারে [need review]
  • G (__K1) + (K2__) = (__K1__) [needs review]
Sondhi for progressive tag POS
  • G (K) + (_) = (K)
Basic Verb Shondhi
  • G (_+ি) + (_) = (_+ে+ও+য়+_)
Verb Shondhi for passive sentence
  • G (C/K + C) + (_) = (C/K+C+_) else
  • G (_+ি) + (_) = (_+ে+ও+য়+_)
Verb Shondhi for active sentence

(Applies if the length of the first word is >= 1, rules are not exclusive e.g. one word can qualify for multiple rules)

  • G (_ে) + (ো) = (_া+ও) e.g. নে + ো = নাও
  • G (C+ে) + (_) = (C+ি+_) e.g. দে -> দি
  • G (ল+ে+C) -> (ল+ি+C) e.g. লেখ -> লিখ [why anubadok repeats this rule?]
  • 3rd person, present simple
  • 2nd person, present simple
  • 1st/2nd/3rd person, future simple
  • 1st/2nd/3rd person, past simple
  • 1st person, present simple
  • 1st/2nd/3rd person, present/past continuous
  • 1st/2nd/3rd person, present/past, perfect
