Big social data repository opened to everybody – Partnership between Department of Informatics at King’s College London and Affectv

Nowadays, we read more and more about big data and how they can be used by companies to their “business advantage”. For the last few years, companies gathered large datasets about their customers, employees, partners, etc. The challenge now is to analyze those data in a way that enables us to discover underlying patterns and trends, and from the business perspective to turn this knowledge into measurable profit.

It is not easy to mine meaningful information from an endless number of bits gathered in our computer systems. Things get even more complicated when we consider data that describes people and their activities as in such a case we have not only information about individuals but also their interactions with others. This means that we have to dig into a large graph that represents this web of connections.

Social targeting company Affectv is one of the businesses that understands the urgent need to look closer at the assets they have. Yes, data is an asset, a very valuable one. Thus, they decided to open up its aggregated social data for a limited period. The Open Graph Initiative kicks off with the Department of Informatics at King’s College London and will roll out to Edinburgh University and Indian Institute of Technology with the aim of sparking innovation within the social media interaction industry.

This partnership aims to help to uncover insights and trends in how social interaction across media platforms affects certain outcomes, for example:
• Can you identify interests based on someone’s social graph?
• Can you infer brand favourability through analysis of a person’s social graph?
• Can you predict purchase intent from social endorsement?
• What social signals reveal the strength of a social connection?

The Open Graph Initiative is organized in a form of challenge that is open to everybody who wants to be involved. It will consist of two open challenges per quarter. Each quarter, Affectv will release the results on its website. Credit will be cited for the relevant parties that uncover the most interesting insights on human behaviour on the social web and will receive press coverage.

We have just received news of successes for our papers at AAMAS 2012 workshops, to be held in Valencia, Spain, in June 2012.  The topics range from adaptive and self-organizing systems, through network science, to automated trading.  This range gives some idea of the diversity in contemporary computer science research.

Martin Chapman, Gareth Tyson, Katie Atkinson, Michael Luck and Peter McBurney [2012]: Social networking and information diffusion in automated markets. In: C. Kiekintveld, O. Shehory, E. David, S. Stein and V. Robu (Editors): Joint International Workshop on Trading Agent Design and Analysis (TADA 2012) and Agent-Mediated Electronic Commerce (AMEC 2012).
