The platform where these tweets are posted is called Timeline. The code is as follows: The preceding figure shows few results from obtained using the classify_polarity() function of sentiment package for Meru Cabs tweets. Similarly, we generated results for other cab-services from our problem setup. That is say that we tend to tweets/report if something bad had happened rather reporting/tweeting if the experience was rather good. Now, my dataset is ready for sentiment extraction. 3. The preceding tweet was tweeted by @TwitterDev and it’s about 132 characters long. After importing the data, you can conduct sentiment analysis. The classifier needs to be trained and to do that, we need a list of manually classified tweets. The ability to categorize opinions expressed in the text of tweets—and especially to determine whether the writer's attitude is positive, negative, or neutral—is highly valuable.

I have created a simple story on this dataset. Got a Twitter dataset from Kaggle; Cleaned the data using the tweet-preprocessor library and the regular expression library; Splitted the training and the test data by 70/30 ratio; Vectorized the tweets using the CountVectorizer library; Built a model using Support Vector Classifier; Achieved a 95% accuracy People who follow @fakingnews are the ones who, in general, like to read sarcasm news. The preceding figure shows word cloud from tweets about TaxiForSure. There is more metadata associated with the same tweet, which are classified by Twitter as entities and places. Friends who are connected or, in case of Twitter, followers, immediately get the information about what’s going on in someone’s life. Within it, many and various communities are originated by users with common interests, or with similar ways to feel part of the community. We have the option to explore the data in python notebook using a library such as Seaborn and Matplotlib. Theoretically, a tweet is just 140 characters of text content tweeted by a user, but there is more to it than just that. It possible the place is a real world location from where the tweet was sent, or it is a location mentioned in the text of the tweet.
