New Feature
Random Augmentation
- Random remove part and generate new sentence

At present it's removing word, stopwords, punctuations, numbers and generate new sentences

py
from bnaug.sentence import RandomAugmentation

raug = RandomAugmentation()
sentence = "আমি ১০০ বাকি দিলাম"
output = raug.random_remove(sentence)
print(output)



or apply individually

py
from bnaug import randaug

text = "১০০ বাকি দিলাম"
output = randaug.remove_digits(text)
print(output)

text = "১০০! বাকি দিলাম?"
output = randaug.remove_punctuations(text)
print(output)

text = "আমি ১০০ বাকি দিলাম"
randaug.remove_stopwords(text)
print(output)

text = "আমি ১০০ বাকি দিলাম"
randaug.remove_random_word(text)
print(output)

text = "আমি ১০০ বাকি দিলাম"
randaug.remove_random_char(text)
print(output)

Sentence Augmentation
Token Replacement
- Mask generation based augmentation

py
from bnaug.sentence import TokenReplacement

tokr = TokenReplacement()
text = "আমি ঢাকায় বাস করি।"
output = tokr.masking_based(text, sen_n=5)


- Word2Vec based augmentation

py
from bnaug.sentence import TokenReplacement

tokr = TokenReplacement()
text = "আমি ঢাকায় বাস করি।"
model = "msc/bangla_word2vec/bnwiki_word2vec.model"
output = tokr.word2vec_based(text, model=model, sen_n=5, word_n=5)
print(output)


- Glove based augmentation

py
from bnaug.sentence import TokenReplacement

tokr = TokenReplacement()
text = "আমি ঢাকায় বাস করি।"
vector = "msc/bn_glove.300d.txt"
output = tokr.glove_based(text, vector_path=vector, sen_n=5, word_n=5)
print(output)


Back Translation
Back translation based augmentation first translate Bangla sentence to English and then again translate the English to Bangla.

py
from bnaug.sentence import BackTranslation

bt = BackTranslation()
text = "বাংলা ভাষা আন্দোলন তদানীন্তন পূর্ব পাকিস্তানে সংঘটিত একটি সাংস্কৃতিক ও রাজনৈতিক আন্দোলন। "
output = bt.get_augmented_sentences(text)
print(output)



Text Generation
- Paraphrase generation

py
from bnaug.sentence import TextGeneration

tg = TextGeneration()
text = "বিমানটি যখন মাটিতে নামার জন্য এয়ারপোর্টের কাছাকাছি আসছে, তখন ল্যান্ডিং গিয়ারের খোপের ঢাকনাটি খুলে যায়।"
output = tg.parapharse_generation(text)
print(output)
