Social Networks and Algorithms
Why Facebook thinks I'm boring.
The algorithm that decides what you are interested in
Networks are made up of nodes and edges.
Facebook Averages
130 Friends
90 pieces of content per month
80 pages, groups and events
25 Comments per month
9 'Likes' per month
My Estimates
95 Friends
1 comment per month
0 Likes (pages, posts, comments, photos)
6 Groups
0 photo uploads
2 tags per month
Edges -
The relationship between you and your 'friends'
How you are 'connected'
Nodes -
Who they are to you
Small world network
In regards to Facebook the middle best represents how we are connected
Affinity - How 'connected' a particular user is to an Edge
Weight - Every action a user takes creates an edge, and a potential story.
Time Decay - As a story gets older, it loses points because it's 'old news.'
