SimpleChinese2 集成了许多基本的中文NLP功能,使基于 Python 的中文文字处理和信息提取变得简单方便。

声明

本项目是为方便个人工作所创建的,仅有部分代码原创。包括分词、词云在内的诸多功能来自于其他项目,并非本人所写,如遇问题,请至原项目链接下提问,谢谢!

安装

pip install -U simplechinese==0.2.8

如从 git 上 clone,需要从以下地址下载词向量文件:

https://drive.google.com/file/d/1ltyiTHZk8kIBYQGbZS9GoO_DwDOEWnL9/view?usp=sharing

并拷贝至"./simplechinese/data/"文件夹下

使用方法

import simplechinese as sc

1. 文字预处理

>>> x = "测试测试,TestING    ;¥%& 01234测试测试"

>>> print(sc.only_digits(x))         # 仅保留数字
01234

>>> print(sc.only_zh(x))             # 仅保留中文

>>> print(sc.only_en(x))             # 仅保留英文

>>> print(sc.punc_norm(x))           # 将中文标点符号转换成英文标点符号
测试,TestING:12345@#[]+=-()..

>>> # y = fillna(df) # 将pandas.DataFrame中的N/A单元格填充为长度为0的str

2. 基础NLP信息提取功能

该部分中,分词功能使用 jieba 实现,源码请参考:https://github.com/fxsjy/jieba

同/近义词查找功能复用了 synonyms 中的词向量数据文件,源码请参考:https://github.com/chatopera/Synonyms 但有所改动,改动如下

  1. 由于 pip 上传文件限制,synonyms 需要用户在完成 pip 安装后再下载词向量文件,国内下载需要设置镜像地址或使用特殊手段,有所不便。因此此处将词向量用 float16 表示,并使用 pca 降维至 64 维。总体效果差别不大,如果在意,请直接安装 synonyms 处理同/近义词查找任务。

  2. 原项目通过构建 KDTree 实现快速查找,但比较相似度是使用 cosine similarity,而 KDTree (sklearn) 本身不支持通过 cosine similarity 构建。因此原项目使用欧式距离构建树,导致输出结果有部分顺序混乱。为修复该问题,本项目将词向量归一化后再构建 KDTree,使得向量间的 cosine similarity 与欧式距离(即割线距离)正相关。具体推导可参考下文:https://stackoverflow.com/questions/34144632/using-cosine-distance-with-scikit-learn-kneighborsclassifier

  3. 原项目中未设置缓存上限,本项目中仅保留最近10000次查找记录。

x = "今天是我参加工作的第1天,我花了23.33元买了写零食犒劳一下自己。"
print(sc.extract_nums(x))              # 提取数字信息
[1.0, 23.33]

# mode: 0: No single character words. The words may be overlapped.
#       1: Have single character words. The words may be overlapped.
#       2: No single character words. The words are not overlapped.
#       3: Have single character words. The words are not overlapped.
#       4: Only single characters.
print(sc.extract_words(x, mode=0))      # 分词
['今天', '参加', '工作', '我花', '23.33', '零食', '犒劳', '一下', '自己']

a = "做人真的好难"
b = "做人实在太难了"
print(sc.string_distance(a,b))  # 编辑距离
0.46153846153846156

x = "种族歧视"
print(sc.find_synonyms(x, n=3))  # 同/近义词
[('种族歧视', 1.0), ('种族主义', 0.84619140625), ('歧视', 0.76416015625)]

3. 繁体简体转换

该部分使用 chinese_converter 实现,源码请参考:https://github.com/zachary822/chinese-converter

>> print(sc.to_traditional(x)) # 转换为繁体 烏龜測試123 >>> x = "烏龜測試123" >>> print(sc.to_simplified(x)) # 转换为简体 乌龟测试123 ">
>>> x = "乌龟测试123"
>>> print(sc.to_traditional(x))  # 转换为繁体
烏龜測試123

>>> x = "烏龜測試123"
>>> print(sc.to_simplified(x))   # 转换为简体
乌龟测试123

4. 特征提取和向量化

5. 词云和可视化

TODO:

  1. 句子向量化及句子相似度
  2. 其他特征提取相关工具
