In Python
>>> from jNlp.jTokenize import jTokenize
>>> input_sentence = u'私は彼を５日前、つまりこの前の金曜日に駅で見かけた'
>>> list_of_tokens = jTokenize(input_sentence)
>>> print list_of_tokens
>>> print '--'.join(list_of_tokens).encode('utf-8')
Returns:
... [u'\u79c1', u'\u306f', u'\u5f7c', u'\u3092', u'\uff15'...] ... 私--は--彼--を--５--日--前--、--つまり--この--前--の--金曜日--に--駅--で--見かけ--た
Katakana Pronunciation:
>>> print '--'.join(jReads(input_sentence)).encode('utf-8')
... ワタシ--ハ--カレ--ヲ--ゴ--ニチ--マエ--、--ツマリ--コノ--マエ--ノ--キンヨウビ--ニ--エキ--デ--ミカケ--タ
Run Cabocha with original EUCJP or IS0-8859-1 configured encoding, with utf8 python
- If cabocha is configured as
utf8then see this http://nltk.googlecode.com/svn/trunk/doc/book-jp/ch12.html#cabocha
>>> from jNlp.jCabocha import cabocha
>>> print cabocha(input_sentence).encode('utf-8')Output:

>>> from jNlp.jConvert import *
>>> input_sentence = u'気象庁が２１日午前４時４８分、発表した天気概況によると、'
>>> print ' '.join(tokenizedRomaji(input_sentence))
>>> print tokenizedRomaji(input_sentence)...kisyoutyou ga ni ichi nichi gozen yon ji yon hachi hun hapyou si ta tenki gaikyou ni yoru to

On English Strings
>>> from jNlp.jProcessing import long_substr >>> a = 'Once upon a time in Italy' >>> b = 'Thre was a time in America' >>> print long_substr(a, b)
Output
...a time in
On Japanese Strings
>>> a = u'これでアナタも冷え知らず'
>>> b = u'これでア冷え知らずナタも'
>>> print long_substr(a, b).encode('utf-8')
Output
...冷え知らず

This section covers (1) Sentiment Analysis on Japanese text using Word Sense Disambiguation, Wordnet-jp (Japanese Word Net file name wnjpn-all.tab), SentiWordnet (English SentiWordNet file name SentiWordNet_3.*.txt).
The following classifier is baseline, which works as simple mapping of Eng to Japanese using Wordnet and classify on polarity score using SentiWordnet.
- (Adnouns, nouns, verbs, .. all included)
- No WSD module on Japanese Sentence
- Uses word as its common sense for polarity score
>>> from jNlp.jSentiments import *
>>> jp_wn = '../../../../data/wnjpn-all.tab'
>>> en_swn = '../../../../data/SentiWordNet_3.0.0_20100908.txt'
>>> classifier = Sentiment()
>>> classifier.train(en_swn, jp_wn)
>>> text = u'監督、俳優、ストーリー、演出、全部最高！'
>>> print classifier.baseline(text)
