Tested on python 3.3
This is a modified version of old mmseg python package, if you want the old version (which support 2.x), try 张沈鹏([email protected]) 修改版 rmmseg-cpp
Due to unknown problem(probably the encoding problem), you need to pass bytes instead of str object to mmseg.
安装:
python setup.py install
用法如:
import mmseg
for i in mmseg.seg_txt("我爱天安门".encode()):
print(i.decode())
输出:
我爱 天安门
pymmseg-cpp by pluskid http://code.google.com/p/pymmseg-cpp/
== DESCRIPTION:
pymmseg-cpp is a Python interface to rmmseg-cpp. rmmseg-cpp is a high performance Chinese word segmentation utility for Ruby. However, the core part is written in C++ independent of Ruby. So I decide to write a Python interface for it in order to use it in my Python project.
== FEATURES/PROBLEMS:
-
Runs fast and the memory consumption is small.
-
Support user customized dictionaries.
-
Only UTF-8 encoding is supported.
== SYNOPSIS:
=== A simple script
pymmseg-cpp provides a simple script (bin/pymmseg), which can read the text from standard input and print the segmented result to standard output. Try pymmseg -h for help on the options.
=== As a Python module
To use pymmseg-cpp in normal Python program, first import the module and init by loading the dictionaries:
from pymmseg import mmseg
mmseg.dict_load_defaults()
Then create a Algorithm object and call next_token until got a None. Or you can simply iterate through it:
algor = mmseg.Algorithm(text) for tok in algor: print '%s [%d..%d]' % (tok.text, tok.start, tok.end)
=== Customize the dictionary
You can load your own character dictionary or word dictionary in the following way:
from pymmseg import mmseg
mmseg.dict_load_words('customize_words.dic') mmseg.dict_load_chars('customize_chars.dic')
The format for the dictionary is very simple. On each line, you specify the frequency followed by an whitespace and then the word/character. Just don't forget the final newline at the end of the file.
== REQUIREMENTS:
- python 2.5
- g++
== INSTALL:
Download the package at http://code.google.com/p/pymmseg-cpp/downloads/list . If you download the source tarball, you'll need to compile it by
make build
if you download the pre-compiled version, this step can be skipped. Then copy the pymmseg directory to your Python's package path. e.g. /usr/lib/python2.5/site-packages/ . Now you can use pymmseg in your application.
