Methodology -
-
We take our input keyword, all the tweets are being automatically shown.
-
For example, if we enter a keyword as "Trump", so, all the tweets about trumps will be shown.
-
We can keep a limit on how many tweets we want. If we want 10 tweets, then only 10 tweets will come up.
-
So, next, we find out the polarity & subjectivity of these tweets.
-
polarity means = how +ve or -ve the text is [-1,1]
-
subjectivity means how much of an opinion it is vs factual
-
Then we store all these in a CSV file (comma seperated file)
-
So, let me tell you how it works,
-
To access tweets we use the Twitter API. So, API means - application programming interface - it is a gateway that lets u access some server's internal functionality, in our case twitter
-
So, when we take an input text like a tweet, we split it up in several words or sentences. this process is called tokenization.
-
we count the number of times, each word shows up, once the text is tokenized, then we look up the sentiment value for each word from a sentiment lexicon that has it all already, pre-recorded to classify the total sentiment value of our tweet this is called bag of words model.

- tweepy - whch access twitter api
- textblob - perform actual sentiment analysis
- pandas - Pandas is mainly used for data analysis. Pandas allows importing data from various file formats such as comma-separated values, SQL, Microsoft Excel. It allows various data manipulation operations such as merging, reshaping, selecting, as well as data cleaning, and data wrangling features.
- time - control time
