Hi All, I am trying to use Mahout for Link Prediction in a Social Network. The data I have is an edges list with 9.4 million rows. The edge list is a csv vile where each node is an integer value and a row represents a edge between two nodes. For example;
3432, 5098 3423, 6710 4490, 5843 4490, 2039 ..... This is a directed graph so row 1 means that node 3432 follows node 5098. I would like to build a recommender to calculate the top 10 nodes a user might like to connect to next. The problem I have is that the recommender classes needs input in the form (user, item, value). So, how can I first calculate a value to represent the 'weight' of an edge? For example EdgeRank? Any help would be greatly appreciated. Thank you, Peter
