pymmseg-cpp by pluskid & kronuz http://github.com/pluskid/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: * Runs fast and the memory consumption is small. * Support user customized dictionaries. * UTF-8 and Unicode 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.Dictionary.load_dictionaries() If you want to load your own customized dictionaries, please customize ``mmseg.Dictionary.dictionaries`` before calling load_dictionaries. Then create an Algorithm iterable object and 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 also 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') ==== Format for chars.dic * each line contains the freq of the character, a space, and then the character ==== Format for words.dic * each line contains the length of the word, a space, and then the word ==== WARNING * The length of the word means number of characters in the word, not number of bytes * The format of words.dic is different from chars.dic, see above * There should be a newline at the end of all the dict file == REQUIREMENTS: * python 2.5 * g++ == INSTALLATION: pymmseg-cpp should be installed using pip or setuptools: pip install pymmseg-cpp easy_install pymmseg-cpp 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 using: python setup.py 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. == CONTRIBUTIONS: Python native extension code contributed by German M.
