Facebook Graph Search: The Power of the Nodes and Edges

According to Mashable, Facebook Graph Search could be it’s greatest innovation. I tend to agree. FB have eight years of Big Data (including almost over two billion new Likes each day) to help us identify products, services and brands that we might need through the experiences of those in our social network.

Actually, a graph consists of only two things; Nodes (people) and edges (their relationships) Analysis of these though can reveal much. The simplest is a measurement of neighbours, the number of edges and their direction. A node with a large number of inward edges (or indegree) can be thought of as popular. One with a large number of outward edges gregarious. If it were possible, Lady Gaga could make a whole boutique full of dresses out of her indegree. Simple analysis of these elements are behind ‘People You May Know’ features in LinkedIn, Chatter, Connections, Jive and Facebook to mention just a few.

New Nodes

Of course, the FB Graph includes other types of nodes (businesses, brands, products) and many other types of edge including the ubiquitous Like. FB also have demographics and psychographics because we surrender more information about ourselves to FB than we would feel comfortable doing in any other survey online or offline. We’re all concerned about privacy but generally end up somewhere around ‘what are you gonna do?’.

These simple elements add up to something very powerful. It’s possible not just to find French restaurants in Frimley but those that are preferred by frequent travellers to the Côte. Not just DIY stores nearby but those popular with power tool enthusiasts. Robert Putnam could have found countless examples for his book on the decline of social capital Bowling Alone. And it is just the beginning. Let’s not forget that those edges include ‘listened’, ‘read’, ‘watched’,’hiked’ and ‘cooked’ to name but a few of the verbs now residing in your facebook apps list and your personal social graph.

Big Data Breakthrough

This is a Big Data breakthrough for Facebook and puts some distance between them and their competitor, Google.  I am not sure that plus’ing is enough of an ‘edge’ at this stage. And for those that can’t see that FB and Google are competitors then remember that there is no revenue in Search. No one actually pays Google to organise the worlds information. Nor do we part with our cash for maintaing personal networks on Facebook. There is, however, a group of people willing to pay for connecting people to products they might enjoy. Advertisers. In other words there is revenue in creating new edges between nodes.  That’s the power of the graph.
