Python : 한글 wordcloud 그리기

0. 패키지 설치 

0.1 konlpy 설치

pip install konlpy         # Python 2.x
pip3 install konlpy        # Python 3.x

0.2 PyTagCloud 설치

 기본 PyTagCloud는 한글이 그려지지 않기 때문에 Lucy Park님이 수정해 주신 PyTagCloud-CJK를 설치해야 함.

git clone https://github.com/e9t/PyTagCloud-CJK.git
cd PyTagCloud
python setup.py install

from collections import Counter
import random
import webbrowser

from konlpy.tag import Hannanum
from lxml import html
import pytagcloud # requires Korean font support
import sys
import requests

r = lambda: random.randint(0,255)
color = lambda: (r(), r(), r())

def get_bill_text_daum():
    url = 'https://media.daum.net/'
    response = requests.get(url)
    text = response.text 
    page = html.fromstring(text)
     
    all_text = page.xpath('//strong[@class="tit_g"]//a/text()')
    corpus = ''
    for text in all_text:
        text = text.replace('\r','').replace('\n','').replace('\t','')
        corpus = corpus + ' ' +text
     
    return corpus

def get_tags(text, ntags=50, multiplier=10):
    h = Hannanum()
    nouns = h.nouns(text)
    count = Counter(nouns)
    return [{ 'color': color(), 'tag': n, 'size': c*multiplier }\
                for n, c in count.most_common(ntags)]

def draw_cloud(tags, filename, fontname='Noto Sans CJK', size=(800, 600)):
    pytagcloud.create_tag_image(tags, filename, fontname=fontname, size=size)
    webbrowser.open(filename)

text = get_bill_text_daum()
tags = get_tags(text)
draw_cloud(tags, 'wordcloud_daum.png')
