mecab-ko-go

A Golang wrapper for mecab-ko.

Dependencies

mecab-ko-go needs mecab-ko and mecab-ko-dic.

Install mecab-ko

Clone repository,

$ git clone git@bitbucket.org:eunjeon/mecab-ko.git

build, and install it:

$ cd mecab-ko
$ ./configure
$ make
$ make check
$ umask 0022
$ sudo make install

Install mecab-ko-dic

Download dictionary file,

$ wget https://bitbucket.org/eunjeon/mecab-ko-dic/downloads/mecab-ko-dic-2.0.1-20150920.tar.gz

unzip it,

$ tar -xzvf mecab-ko-dic-2.0.1-20150920.tar.gz

and install it:

$ cd mecab-ko-dic-2.0.1-20150920
$ ./configure
$ make
$ sudo make install

If it fails with automake, run autogen.sh before configure like this:

$ ./autogen.sh
$ ./configure
$ make
$ sudo make install

(Only on Linux) if it still fails with libmecab.so.2, do the following and try again:

$ sudo ldconfig

Build/Install

If mecab-config is installed,

If you have mecab-config installed, do the following:

$ export CGO_LDFLAGS="`mecab-config --libs`"
$ export CGO_FLAGS="`mecab-config --inc-dir`"

If not,

Do the following:

$ export CGO_LDFLAGS="-L/path/to/lib -lmecab -lstdc++"
$ export CGO_CFLAGS="-I/path/to/include"

You should change /path/to to yours, like:

# (example)
$ export CGO_LDFLAGS="-L/usr/local/lib -lmecab -lstdc++"
$ export CGO_CFLAGS="-I/usr/local/include"

Now install mecab-ko-go with following command:

$ go get -u github.com/meinside/mecab-ko-go

Examples

package main

import (
	"fmt"

	"github.com/meinside/mecab-ko-go"
)

const (
	sampleSentence = "아버지, 지금이 몇 시인지나 알고 가방에 들어가십니까?"
)

func main() {
	m, err := mecab.New()
	if err != nil {
		panic(err)
	}
	defer m.Destroy()

	tg, err := m.NewTagger()
	if err != nil {
		panic(err)
	}
	defer tg.Destroy()

	lt, err := m.NewLattice(sampleSentence)
	if err != nil {
		panic(err)
	}
	defer lt.Destroy()

	node := tg.ParseToNode(lt)
	for {
		feature := node.Feature()
		tag, _ := mecab.NewTag(feature)

		if tag.Tag == "NNG" {
			fmt.Printf("[명사] %s (%s)\n", node.Surface(), feature)
		} else {
			fmt.Printf("[기타/%s] %s (%s)\n", tag.Description, node.Surface(), feature)
		}

		if node.Next() != nil {
			break
		}
	}
}

It will output:
