Co-Commenting Concept

Introduction

Co-commenting is a concept used to explore relations between YouTube videos based on user interactions in comment sections. If a user comments on several videos, a connection is established between those videos, reflecting possible affinity or thematic similarity.

In Graph Terms

Nodes: each node represents a YouTube video.
Edges: a link is created between two videos if at least one user commented on both.
Edge weights: the weight of each link is proportional to the number of users who co-commented on the two videos.

Such a network is often analyzed to identify clusters or communities of videos attracting similar audiences.
