Sentence Augmentation
Token Replacement
-
Mask generation based augmentation
from bnaug.sentence import TokenReplacement tokr = TokenReplacement() text = "আমি ঢাকায় বাস করি।" output = tokr.masking_based(text, sen_n=5)
-
Word2Vec based augmentation
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
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.
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
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)
Random Augmentation
-
Random remove part and generate new sentence
At present it's removing word, stopwords, punctuations, numbers and generate new sentences
from bnaug.sentence import RandomAugmentation raug = RandomAugmentation() sentence = "আমি ১০০ বাকি দিলাম" output = raug.random_remove(sentence) print(output)
or apply individually
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)
