you have two func for Chinese text Data Augmentation

Install textda

pip install:

pip install textda
  1. you can expansion data use data_expansion
from textda.data_expansion import *
print(data_expansion('生活里的惬意,无需等到春暖花开'))

param explain:

:param sentence: input sentence text
:param alpha_sr: Replace synonym control param. bigger means more words are Replace
:param alpha_ri: Random insert. bigger means more words are Insert
:param alpha_rs: Random swap. bigger means more words are swap
:param p_rd: Random delete. bigger means more words are deleted
:param num_aug: How many times do you repeat each method
  • you can use parameters alpha_sr, alpha_ri, alpha_rs, p_rd, num_aug can control ouput.

    if you set alpha_ri and alpha_rs is 0 that means use linear classifier for it, and insensitive to word location

    like this:

      
    from textda.data_expansion import *
    
    print(data_expansion('生活里的惬意,无需等到春暖花开', alpha_ri=0, alpha_rs=0))
    

    output:

    ['生活里的惬意,无需等到春暖花开', 
        ',无需春暖花开', 
        '生活里面的惬意,无需等到春暖花开', 
        '生活里的惬意,需等到春暖花开']
      
  1. you can use translate_batch like this:
from textda.youdao_translate import *
dir = './data'
translate_batch(os.path.join(dir, 'insurance_train'), batch_num=30)
# translate results:  chinese->english and english -> chinese

颜色碰掉了一个角不延迟,但事情或他们不赠送,或发送,眉笔打开已经破碎,磨山楂,也不打破一只手,轻轻刷掉,持久性不长,
这个用户没有填写评价内容
颜色非常不喜欢它
不说话,缓慢的新领域
不太容易染好骑吗
不是很好我喜欢!
没有颜色的眼影
应该有大礼物盒眼影,礼物不礼物盒,没有一起破碎粉碎好的眼影不买礼物清洁剂脏就像商品是压力
没有生产日期,我不知道是否真实,总是觉得有点奇怪
是一个小飞粉吗
但是一些混合的颜色
有几次,现在这个东西,笔是空的
眼影有点小,少一点。
不好的颜色,粉红色
明星不想买,坏了,不容易,不要在乎太多!
一开始我已经联系快递,快递一直拖,说他将返回将联系快递服务
画不是,是不好的
物理和照片有很大的区别
不要把眼影刷不是很方便
感觉好干,颜色更暗
打破了在运输途中,有点太脆弱…
盒子有点坏了,还没有发送。
