Methods

Data Processing

We want to know trend of reddit post within a week. By plotting number of post and day they were posted, we will know the most active-day on reddit forum. We do that by aggregating timestamp into date and day of the week (day name).

Get Sentiment Value for title and body post

We do that by separating title and body column into their own dataframe, drop na, do stemming, clean the text, obtain the sentiment values using nltk SentimentIntensityAnalyzer, and then we plot them.

Generate Wordlouds

We generate wordclouds for both title and body, also wordclouds for each sentiment (negative, positive, and neutral). Detail can be seen in the code ipynb file.
