Ruby + Twitter API でツイートの位置情報を取得する

More than 3 years have passed since last update.

概要

ツイートに付加されている位置情報を Ruby + Twitter API で取得し、どのようなレスポンスが返ってきているのかを調べる。

位置情報ツイートの種類

今回、位置情報を取得するツイートのタイプは以下の3種類。

tweets.png

  • 場所を指定したツイート
  • 場所と正確な位置情報を指定したツイート
  • Swarm (by Foursquare) アプリ https://ja.swarmapp.com/ からのツイート

『正確な位置情報』は、公式 Twitter アプリからツイートする際に付加することができる。

コールする Twitter API

今回コールする Twitter の API は以下の2種類。

ツイートの位置情報を取得するサンプルコード

twitter_api ライブラリのインストール

Twitter API のラッパー・ライブラリ https://rubygems.org/gems/twitter_api をインストール。

$ gem install twitter_api

サンプルコード

require 'twitter_api'
require 'json'

# Twitter API の認証情報をセット
t = TwitterAPI::Client.new({
  :consumer_key => 'YOUR_CONSUMER_KEY',
  :consumer_secret => 'YOUR_CONSUMER_SECRET',
  :token => 'YOUR_ACCESS_TOKEN',
  :token_secret => 'YOUR_ACCESS_SECRET'
})

def show_tweet(t, status_id)

  # GET statuses/show/:id
  s_res = t.statuses_show_id({'id' => status_id})
  status = JSON.parse(s_res.body)
  place_id = status['place']['id'] if status['place'] && status['place']['id']

  # GET geo/id/:place_id
  if place_id
    p_res = t.geo_id_place_id({'place_id' => status['place']['id']})
    place = JSON.parse(p_res.body)
  end

  puts "========== Status ID: #{status_id} =========="
  puts JSON.pretty_generate({'text' => status['text']})
  puts JSON.pretty_generate({'geo' => status['geo']})
  puts JSON.pretty_generate({'coordinates' => status['coordinates']})
  if place
    puts "========== Place ID: #{place_id} =========="
    puts JSON.pretty_generate({'name' => place['name']})
    puts JSON.pretty_generate({'geometry' => place['geometry']})
    puts JSON.pretty_generate({'centroid' => place['centroid']})
  end

  puts '========== GET statuses/show/:id =========='
  puts JSON.pretty_generate(status)

  if place
    puts '========== GET geo/id/:place_id =========='
    puts JSON.pretty_generate(place)
  end
end

# JR名古屋駅 – 場所: JR 名古屋駅
show_tweet(t, '844701177438781441')

# JR名古屋駅 + 正確な位置情報 – 場所: JR 名古屋駅
show_tweet(t, '844701423103365124')

# Swarm (@ JR 名古屋駅 in Nagoya-shi, Aichi-ken)
show_tweet(t, '844701716528447492')

ツイートから取得した位置情報

場所を指定したツイート

場所を指定したツイートでは、ツイートの情報に緯度・経度は含まれない。

場所 (Place) の情報に緯度経度が含まれている。こちらは、場所が持つエリア (ポリゴン) の中心点 (重心 centroid) だと思われる。

========== Status ID: 844701177438781441 ==========

場所と正確な位置情報を指定したツイート

場所と正確な位置情報を指定したツイートでは、ツイートの情報に緯度・経度が含まれる。

場所 (Place) の情報にも緯度経度が含まれている。こちらも、場所が持つエリア (ポリゴン) の中心点 (重心 centroid) だと思われる。

Swarm (by Foursquare) からのツイート

Swarm (by Foursquare) からのツイートでは、ツイートの情報に緯度・経度が含まれる。

場所 (Place) の情報にも緯度経度が含まれているが、指定した「JR 名古屋駅」ではなく、なぜか「名古屋市 中村区」に紐付いている。
