In this chapter, we will analyze the YouTube channel of Sony PlayStation, a very popular brand among youth, and rank their published videos in terms of popularity (views, likes, and dislikes) and also go deeper in the analysis by measuring the evolution of sentiment in terms of user comments generated for one particular video and show it on a timeline. It gives a good understanding of the popularity and attitude trends of the viewers.

This approach requires a few steps. The first step to rank videos requires us to extract the statistics, while the second requires us to gather the comments data, clean it, and calculate the sentiment measure. Finally, it will be analyzed in time-series.

This process requires us to gather both structured and unstructured data:

• Structured data: The number of views, likes, and dislikes of all videos
• Unstructured data: The comments generated for one video
