  11. 11. The Order of Social Machines Real life is and must be full of all kinds of social constraint – the very processes from which society arises. Computers can help if we use them to create abstract social machines on the Web: processes in which the people do the creative work and the machine does the administration… The stage is set for an evolutionary growth of new social engines. Berners-Lee, Weaving the Web, 1999
  12. 12. Some Social Machines
  13. 13. SOCIAM: The Theory and Practice of Social Machines • Southampton Shadbolt, Hall, Berners-Lee, Moreau • Edinburgh Robertson, Buneman • Oxford De Roure, Lintott, OII http://www.sociam.org/
  14. 14. http://gow.epsrc.ac.uk/NGBOViewGrant.aspx?GrantRef=EP/J017728/1 • Research into pioneering methods of supporting purposeful human interaction onBehaviour Wide Web, of the World is socially the kind exemplified by phenomena such as Wikipedia and constituted, not Galaxy Zoo. programmed in • These collaborations are empowering, as communities identify and solve their own problems, harnessing their commitment, local knowledge and embedded skills, without having to rely on remote experts or governments. • The ambition is to enable us to build social machines that solve the routine tasks of daily life as well as the emergencies… to develop the theory and practice so that we can create the next generation of decentralised, data intensive, social machines. We are interested in design • Understanding the attributes of the current generation of successful social machines will help us build the next.

  17. 17. Composing Social Machines “The myExperiment social machine protected by the reCAPTCHA social machine was attacked by the spam social machine so we built a temporary social machine to delete accounts using people, scripts and a blacklisting social machine then evolved the myExp social machine into a new social machine…”

  45. 45. Closing thoughts 1. The future is Big Data and Big Social… and with increasing automation (there be dragons!) 2. The Theory, Practice, Design and Construction of Social Machines are emerging areas of study 3. You are knowledge infrastructure and Social Machines designers… it may be useful to think about your projects in terms of Social Machines 4. Think about Semantic Web plus Social Machines for tomorrow’s knowledge infrastructure: policy, provenance, composition, social objects
