2.  In this paper,  Authors investigate on the potential of combining social and technical networks to collaboratively provide services.  In the Internet of Things (IoT),  Things talk and exchange information.  Socio-technical network.  Distributed sensor-actor environments.  Humans and technical systems. Abstract. Data & Knowledge Engineering Lab.1

3.  World: 1/7, Korea: 1/5 Social network. Data & Knowledge Engineering Lab.2

4.  The idea of the IoT.  Linking digital information to a network and there by relating digital information to real world physical items.  Bleecker[1]:  As more smart, mobile, sensing ‘Things’ are attached to the Internet, their presence and participation and agency can be felt in our online lives (2 nd Life).  “If the social web (IoT) greatly impacted our social lives, how will an Internet of Things be felt across our lived experiences? ” Socio-Technical Networks. Data & Knowledge Engineering Lab.3 [1] Bleecker, J., “The Internet of Things: What Happens When 1 st Life & 2 nd Life Meet Up?”, 2006

5.  Bleecker’s Focus.  What such a social web might look like when network connected ‘Things’ participate.  Our Focus.  What the technical systems can themselves participate in socio-technical networks. Socio-Technical Networks. Data & Knowledge Engineering Lab.4

6.  Technological networks.  Distributed wireless sensor networks.  They share data to accomplish dedicated tasks by exchanging, assessing and processing information.  Motivations.  Networked objects exchange data among themselves.  This data is invisible for human users.  There is a plentitude of information.
