Social Network analysis using Hadoop

February 2014 to Present

Members:Prashanth Sandela, Siddartha Reddy

Our goal is to identify which people know each other(eg, friends, acquaintances) by looking at when and where they've been.

We are using a data set consisting of 6 million checkins, the idea is that if they've been to the same place at about the same time, they probably know each other. The more times we see them together like this, the stronger the inferred friendship.

We feel once we have this basic info, then we can construct a node+edge graph and run various algorithms on it. For example, finding the connected components within a certain node-hop-distance would be to find the social networks(eg, your friends, and friends of friends).
