WhatsApp Chat Sentiment Analysis using Python

Now let’s start with the task of WhatsApp chat sentiment analysis with Python. I’ll start this task by defining some helper functions because the data we get from WhatsApp is not a dataset that is ready to be used for any kind of data science task. So, to prepare your data for the sentiment analysis task, just define all the functions as defined below:

It doesn’t matter if you are using a group chat dataset or your conversation with one person. All the functions defined above will prepare your data for the task of sentiment analysis as well as for any data science task. Now here is how we can prepare the data we collected from WhatsApp by using the above functions:

Now here is how we can analyze the sentiments of WhatsApp chat using Python:

        Date      Time        Author  ... Positive  Negative  Neutral
0 2020-04-06  12:30 pm         Sapna  ...      0.0     0.000    1.000
1 2020-04-06  12:30 pm         Sapna  ...      0.0     0.000    1.000
2 2020-04-06  12:54 pm  Aman Kharwal  ...      0.0     0.000    1.000
3 2020-04-06  12:55 pm         Sapna  ...      0.0     0.383    0.617
4 2020-04-06   1:00 pm  Aman Kharwal  ...      0.0     0.000    1.000

Output:
Neutral 🙂

So, the data I used indicates that most of the messages between me and the other person are neutral. Which means it’s neither positive nor negative.
