  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

We are interested in design • Understanding the attributes of the current generation of successful social machines will help us build the next.

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
