最近需要从文本中抽取结构化信息,用到了很多github上的包,遂整理了一下,后续会不断更新。
|
|
|
|
|
|
|
|
|
|
很多包非常有趣,值得收藏,满足大家的收集癖!

|
**1\. textfilter: 中英文敏感词过滤** [observerss/textfilter](https://github.com/observerss/textfilter)
|
|
|
|
|
```
|
|
|
|
|
>>> f = DFAFilter()
|
|
|
|
|
>>> f.add("sexy")
|
|
|
|
|
>>> f.filter("hello sexy baby")
|
|
|
|
|
hello **** baby
|
|
|
|
|
```
|
|
|
|
|
敏感词包括政治、脏话等话题词汇。其原理主要是基于词典的查找(项目中的keyword文件),内容很劲爆。。。
|
|
|
|
|
|
|
|
|
|
**2\. langid:97种语言检测** [https://github.com/saffsd/langid.py](https://github.com/saffsd/langid.py)
|
|
|
|
|
|
|
|
|
|
> pip install langid
|
|
|
|
|
```
|
|
|
|
|
>>> import langid
|
|
|
|
|
>>> langid.classify("This is a test")
|
|
|
|
|
('en', -54.41310358047485)
|
|
|
|
|
```
|
|
|
|
|
**3\. langdetect:另一个语言检测**[https://code.google.com/archive/p/language-detection/](https://code.google.com/archive/p/language-detection/)
|
|
|
|
|
|
|
|
|
|
> pip install langdetect
|
|
|
|
|
```
|
|
|
|
|
from langdetect import detect
|
|
|
|
|
from langdetect import detect_langs
|
|
|
|
|
|
|
|
|
|
s1 = "本篇博客主要介绍两款语言探测工具,用于区分文本到底是什么语言,"
|
|
|
|
|
s2 = 'We are pleased to introduce today a new technology'
|
|
|
|
|
print(detect(s1))
|
|
|
|
|
print(detect(s2))
|
|
|
|
|
print(detect_langs(s3)) # detect_langs()输出探测出的所有语言类型及其所占的比例
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
输出结果如下: 注:语言类型主要参考的是ISO 639-1语言编码标准,详见[ISO 639-1百度百科](https://baike.baidu.com/item/ISO%20639-1)
|
|
|
|
|
|
|
|
|
|
跟上一个语言检测比较,准确率低,效率高。
