Collecting Data

In this first part, we’ll see different options to collect data from Twitter. Once we have built a data set, in the next episodes we’ll discuss some interesting data applications.

Step 1.- Register Your App

In order to have access to Twitter data programmatically, we need to create an app that interacts with the Twitter API.

The first step is the registration of your app. In particular, you need to point your browser to http://apps.twitter.com, log-in to Twitter (if you’re not already logged in) and register a new application . You can now choose a name and a description for your app (for example “Social Media Data analysis ” or similar). You will receive a consumer key and a consumer secret: these are application settings that should always be kept private.

Accessing the Data

Twitter provides REST APIs you can use to interact with their service. In particular, Tweepy in one of the most interesting and straightforward to use, so let’s install it:

pip install tweepy==3.3.0

In order to authorise our app to access Twitter on our behalf, we need to use the OAuth interface:

import tweepy
from tweepy import OAuthHandler
 
consumer_key = 'YOUR-CONSUMER-KEY'
consumer_secret = 'YOUR-CONSUMER-SECRET'
access_token = 'YOUR-ACCESS-TOKEN'
access_secret = 'YOUR-ACCESS-SECRET'
 
auth = OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_secret)
 
api = tweepy.API(auth)

Whats Polarity & Subjectivity?

Polarity: Polarity score is a float within the range [-1.0, 1.0], also known as orientation polarity is the emotion expressed in the sentence. It can be positive, negative or neutral.

Subjectivity: It measures subjectivity of sentence or to what extent it represents someones personal feelings, views, or beliefs compared to objective truth or facts. subjectivity is a float within the range [0.0, 1.0] where 0.0 is very objective and 1.0 is very subjective.

import tweepy
from textblob import TextBlob

import os
import csv


        
# Step 1 - Authenticate
consumer_key = 'YOUR-CONSUMER-KEY'
consumer_secret = 'YOUR-CONSUMER-SECRET'
access_token = 'YOUR-ACCESS-TOKEN'
access_secret = 'YOUR-ACCESS-SECRET'

auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)

api = tweepy.API(auth)



# Step 3 - Retrieve Tweets

public_tweets = api.search('Soulworker ')

# CHALLENGE - Instead of printing out each tweet, save each Tweet to a CSV file
# and label each one as either 'positive' or 'negative', depending on the sentiment
# You can decide the sentiment polarity threshold yourself

print("Sentiment for Individual Tweet")


for tweet in public_tweets:
    print(tweet.text)

    # Step 4 Perform Sentiment Analysis on Tweets
    analysis = TextBlob(tweet.text)
    print(analysis.sentiment)
    print("")
    print('polarity: {}'.format(analysis.sentiment.polarity))
    print("")
    print('subjectivity: {}'.format(analysis.sentiment.subjectivity))
    print("")
