ws = ckip_classic.ws.CkipWs(logger=False)
print(ws('中文字喔'))
for l in ws.apply_list(['中文字喔', '啊哈哈哈']): print(l)

ws.apply_file(ifile='sample/sample.txt', ofile='output/sample.tag', uwfile='output/sample.uw')

    print(fin.read())
with open('output/sample.uw') as fin:
    print(fin.read())

CKIPParser

import ckip_classic.parser
print(ckip_classic.__name__, ckip_classic.__version__)

ps = ckip_classic.parser.CkipParser(logger=False)
print(ps('中文字喔'))
for l in ps.apply_list(['中文字喔', '啊哈哈哈']): print(l)

ps.apply_file(ifile='sample/sample.txt', ofile='output/sample.tree')
with open('output/sample.tree') as fin:
    print(fin.read())

FAQ

!DANGER!

Due to C code implementation, both CkipWs and CkipParser can only be instance once.

Warning

CKIPParser fails if input text contains special characters such as ()+-:|&#. One may replace these characters by

text = text
   .replace('(', '（')
   .replace(')', '）')
   .replace('+', '＋')
   .replace('-', '－')
   .replace(':', '：')
   .replace('|', '｜')
   .replace('&', '＆') # for tree draw
   .replace('#', '＃') # for tree draw

Tip

The CKIPWS throws “what(): locale::facet::_S_create_c_locale name not valid”. What should I do?

Install locale data.

apt-get install locales-all

---

Tip

The CKIPParser throws “ImportError: libCKIPParser.so: cannot open shared object file: No such file or directory”. What should I do?

Add below command to ~/.bashrc:

export LD_LIBRARY_PATH=<ckipparser-linux-root>/lib:$LD_LIBRARY_PATH
