my own Web.

• Web technologies enabled users to be proactive on the Web.

• Exciting times ahead: semantic Web Technologies, Linked DataPlatform, Push API, WebRTC, CoAP, etc.

• How about things?

Pro-activeness

• Properties of agents (the weak notion of agency) [Wooldridge et al.,

1995]:

• social ability;• reactivity;• autonomy;• pro-activeness: the ability to exhibit goal-driven behavior by taking

the initiative.

• Multi-agent systems [Boissier, 2012]:

(SWoT)

Objective and Motivation

• Placing autonomous and proactive things on the Web.

• Where to start?• Extend and transform social networks into socio-technical

networks (STN) by introducing autonomous and proactivethings as full-fledged users and service providers.

• Such a STN would be suitable for:• providing a good experience to the WoT user (straightforward

model of interaction);• extending the perception of things by tapping into the rich

amount of information being published on social networks;• providing a framework for the development of complex WoT

applications.

Challenges

• Enable things as active participants in an open set of socialnetworks.

• Enable things to reason and make decisions in achieving theirgoals.

• Enable control over the autonomy of things and enhancecoordination towards achieving goals.

• Connectivity: Integration at the level of the social networking service(SNS).

• Relationship management: Hardcoded in the agent.

• Decision-making: Based on agent’s knowledge.

• Coordination mechanisms: Hardcoded in the agent.

• Control of autonomy: Application-level.

The Social Layer

• What would a STN look like?

• The Socio-technical Graph (STG) is an edge-labeled directedmultigraph.

• Uniform interface: the set of common relevant nouns in SNSs.

Agents in organizations

• Organizational models: AGR [Ferber et al., 2004], MOISE+[Hubner et al., 2007], OperA [Dignum, 2004], etc.

• Organizations can enable control on 3 dimensions: structural,communication, and functional.

• A SWoT app for student houses:• Setting:

• 6 floors;• 20 studios and 1 laundry room per floor;• 1 washing machine and 1 dryer per laundry room.

• Objectives:• Enhance interaction among students.• Improve the QoS of the laundromats.

Structural control

Hello StudentHouse!I’m Joe’s door

and I’m enactingrole Door in

group 3rd floor.

Hello Joe’s door!In this student

house, all Doorsare connected.

• The structural specification can encourage or discourageconnections in the STG.

• Agents in organizations

• Connectivity: Access to an open set of social networks.• Relationship management: Can be enforced at the organizational

level.• Decision-making: Based on collective and organizational knowledge.• Coordination mechanisms: Organizational proceses (e.g. goal

decomposition trees).• Control of autonomy: Organization-level.

• We have offered an interpretation on the evolution of the Webfrom several perspectives: socialness, pervasiveness, andpro-activeness.

• We have defined and motivated our vision for the SWoT atthe convergence of these 3 dimensions.

• We have discussed a possible approach towards implementingthis vision, introducing a layer of normative organizations for:

• bringing more autonomy to things;• enabling control over the autonomy of things;• supporting coordinated behavior in SWoT apps.
