Use mecab-ipadic-neologd with igo-python

It is assumed that MeCab is already installed.

procedure

Install igo-python pip install igo-python
Download igo-0.4.5.jar
Download mecab-ipadic-neologd (git clone)
Go to mecab-ipadic-neologd and run ./bin/install-mecab-ipadic-neologd. Then you will have a build directory.
Copy ʻigo-0.4.5.jartomecab-ipadic-neologd / build / mecab-ipadic-2.7.0-20070801-neologd-20150401 and execute the following command java -cp igo- 0.4.5.jar net.reduls.igo.bin.BuildDic neologd. "utf-8" `

That's it. I will try to see if it worked.

In [1]: import igo

In [2]: t  = igo.tagger.Tagger('neologd')  #Java earlier~Path to the directory created in

In [3]: for i in t.parse(u'Apple will release the Apple Watch domestically on April 24th.'):

You can't get Apple Watch all at once with regular MeCab, but thanks to mecab-ipadic-neologd, you can get it. This time I ran it in the directory where neologd was created, so there was no problem, but as I wrote in the comment, when actually using it, you need to pass the path to the created neolog directory.

This is convenient because you can flexibly analyze morphological elements without installing MeCab.

Explanation of commands for compiling dictionaries for igo

In the directory where igo-0.4.5.jar is located java -cp igo-0.4.5.jar net.reduls.igo.bin.BuildDic path to the directory storage directory Character code to the buid directory in mecab-ipadic-neologd

Error compiling dictionary for igo

ʻException in thread "main" java.lang.OutOfMemoryError: If you get an error like Java heap space, add -Xmx1024m` to the options. I don't know the details, but it seems that the heap is not enough, so I would like to see it by specifying the size.

java -Xmx1024m -cp igo-0.4.5.jar net.reduls.igo.bin.BuildDic neologd . "utf-8"

I referred to here, but I got the same error on 1024, so I managed to double it to 2048. Then the error disappeared.

I referred to the following article. Thank you very much.
