This post is first in a series that looks at the inferences you can make using social media data. The current analysis is a by-product of the Me Meme Twitter client that recently soft launched. Me Meme organizes your timeline into separate feeds based on your interests, helping you conquer information overload. It leverages Panoptez, a hosted Model as a Service from Zato Novo.

Prevailing wisdom says that who you associate with says a lot about you. By analyzing your social media graph, I can confirm that this claim has merit. Remarkably, it can also reveal non-obvious interests that provide insights into a person. This knowledge can be used for marketing, sales, or even plain-old relationship building.

First a bit of background. Panoptez, is a suite of models that I’ve developed and am licensing. They are components that are used to build custom data-driven applications. (See The Models as a Service Era has arrived for more information on this idea.) An example is the interplay between Panoptez and Me Meme. Panoptez provides the intelligence of extracting groups of people with similar interests and generating representative keywords that describe those groups. Me Meme uses this model output to display a Twitter timeline in separate feeds, so that each feed only contains tweets by the people in the group. Like a newspaper organized by sections, your feed becomes organized based on your individual interests. So Panoptez makes inferences, and Me Meme applies it to a specific problem.

What’s fascinating is the level of insight that can be gleaned from something as simple as a social graph. Take, for example, the NYC venture capitalist Matt Turck. What does his social graph say about him? Here are some of the groups Panoptez found within his social graph.

Group labels Number of members Sample user – description
founder ceo, new york, venture capital 639 slazar – Doing what I can to help technology start-ups break through the noise as a Principal at General Catalyst (@gcvp) in NYC.
big data, design data, founder ceo, founder cto 115 Kellblog – CEO of Host Analytics, the leader in cloud-based enterprise performance management. See FAQ on Kellblog for disclaimers, including list of affiliations.
big data, data scientist, data science, chief data scientist, data analytics 114 statpumpkin – Director of Statistics Research – AT&T

bloomberg lp, bloomberg link, social media 26 evghood – Austin born. TCU grad. Current New Yorker. Works at Bloomberg LINK @bbglink. Small dog named Bo. Married to @cwhood.
internet of things, smart home, smartphone apps 22 iotwatch – founder @GNLteam / consultant at @designswarm / editor @ConnectedIOT / CEO @tinkerlondon /organiser @iotlondon @liquid_con @iotangels @techcityiwd / FRSA
founder ceo, frances startup, frances startup blog 21 LaFrenchTech La #Frenchtech est le nom collectif pour désigner tous les acteurs de l’« écosystème de #startups » français. #innovation #france

These groups appear to isolate Matt’s interests. But how do we know for sure that these interests are accurate? Since I don’t know Matt personally, I can’t just ask him. Thankfully Matt blogs and has an informative bio that we can use a form of validation:

“Partner at FirstMark Capital. Previously, Managing Director at Bloomberg Ventures and before that, co-founder of TripleHop Technologies, acquired by Oracle. Occasional angel investor. Startup mentor (Techstars, DreamIt, ERA, FGVN, NYC Venture Fellows). Organizer of two large monthly tech community events, Data Driven NYC and Hardwired NYC.”

So his bio validates a number of the groups identified by Panoptez. This is further confirmed by his blog posts:

What have we learned from this post? For a given user, we’ve managed to extract key interests of that user by simply analyzing the user’s social graph. Throw in a dash of natural language processing to generate summary labels for the groups, and we have a powerful model for understanding users. All of this can be provided as a simple hosted model/data service that requires no infrastructure build-out nor a data science team.

Appendix

For those interested in leveraging Panoptez, there are two ways to access it (after subscribing to the service). The preferred approach is via a REST API and data feed. Alternatively, it is possible to work with the Panoptez R library directly. This analysis only requires three function calls:

> uc <- user_community(user.id)
> list_communities(uc)

  0   1   2   3   4   5   6   7   8   9  10
  8  21   4   9 639  26  29  22 115 114   6

> head(print_community(1,uc),10)
