Sentiment Analysis of Twitter
[Back] Within the Twitter API we can mine for tweets. In this case we will take a key search word and then find the 10 most recent tweets, and then give a sentiment score. A value of 0.0 is neutral. A positive score is a positive sentiment, and a negative score is a negative sentiment [Reddit Top Posts][Reddit with search for keyword].
Within the Twitter API was can search for keywords, and then mine for their sentiment. In the following we search for the last 10 tweets for the key word of "cybersecurity":
import tweepy import tweepy as tw import re from textblob import TextBlob import sys consumer_key = 'xxxxx' consumer_secret = 'xxxx' access_key= 'xxxx' access_secret = 'xxxxx' auth = tweepy.OAuthHandler(consumer_key, consumer_secret) auth.set_access_token(access_key, access_secret) api_obj = tweepy.API(auth) search_term = "cyber+security" if (len(sys.argv)>1): search_term=(sys.argv) print "Search term: ",search_term search_results = api_obj.search(q=search_term, count=10) res =  for tw in search_results: res.append(tw.text.encode('ascii', 'ignore')) sentiment_objects = [TextBlob(tweet) for tweet in res] sentiment_values = [[tweet.sentiment.polarity, str(tweet)] for tweet in sentiment_objects] score=0 for s in sentiment_values: score = score+float (s) print "Overall score from 10 tweets: ", score print i=0 for s in sentiment_values: i=i+1 print i, if float (s) > 0: print 'Positive ', elif float(s) == 0: print 'Neutral ', else: print 'Negative ', print "Score: ",s, "Text: ",s print
