Pythonで日本語形態素解析

Last updated at Posted at 2016-01-29

Pythonで日本語形態素解析をしてみようと思います。
APIがYahooから出ているのでそれを利用していきます。

まず、POSTする際に必須であるパラメーターは
・appid
・sentence
・results
の3点です。
詳しくPOSTしたい人はパラメーター追加してください。

appidはYahooで登録すれば取得できます。
sentenceは形態素解析する本文です。
resultsはレスポンスの形式指定用です。

形態素解析.py
#coding: utf-8

import requests
from xml.etree.ElementTree import *

def POST(body):
	request_URL = "http://jlp.yahooapis.jp/MAService/V1/parse"

	parameter = {'appid': 'Your appid!',
				'sentence': body,
				'results': 'ma'}
	r = requests.get(request_URL, params=parameter)
	yield (r, r.text)

def XML_parse(body):
	elem = fromstring(body)
	for e in elem.getiterator("{urn:yahoo:jp:jlp}surface"):
		print e.text

if __name__ == '__main__':
	for response in POST(body="今日はいい天気ですね"):
		r = response[0]
		text = response[1]
	XML_parse(text.encode('utf-8'))#encodeしないとUnicode-error
