Is there any good open-source or freely available Chinese segmentation algorithm available? [closed]

Question

As phrased in the question, I'm looking for a free and/or open-source text-segmentation algorithm for Chinese, I do understand it is a very difficult task to solve, as there are many ambiguities involed. I know there's google's API, but well it is rather a black-box, i.e. not many information of what it is doing are passing through.

Answer 1

The keyword text-segmentation for Chinese should be 中文分词 in Chinese.

Good and active open-source text-segmentation algorithm :

1. 盘古分词(Pan Gu Segment) : C#, Snapshot
2. ik-analyzer : Java
3. ICTCLAS : C/C++, Java, C#, Demo
4. NlpBamboo : C, PHP, PostgreSQL
5. HTTPCWS : based on ICTCLAS, Demo
6. mmseg4j : Java
7. fudannlp : Java, Demo
8. smallseg : Python, Java, Demo
9. nseg : NodeJS
10. mini-segmenter: python

Other

1. Google Code : http://code.google.com/query/#q=中文分词
2. OSChina (Open Source China)

Sample

1. Google Chrome (Chromium) : src, cc_cedict.txt (73,145 Chinese words/pharases)

   • In text field or textarea of Google Chrome with Chinese sentences, press Ctrl+← or Ctrl+→

   • Double click on 中文分词指的是将一个汉字序列切分成一个一个单独的词

Answer 4

Cursory Googling for "text segmentation chinese open source" reveals this library, which may or may not be what you're looking for...:

http://sourceforge.net/projects/ktdictseg/

The results hint at a few alternative venues to look for an open-source library, too:

• Searching for an open-source search implementation that might work with Chinese.
• Searching for an open-source plagiarism detection implementation that might with Chinese.
