John S Gero Agents – Agent Societies Communication communicate - “to make common” communicative action = “a social action oriented to reaching understanding” (Habermas)  understanding includes consensus! communication as a means for negotiation (Sycara) DADA DBDB DCDC consistent design goals Agent A Agent B Agent C Observer

John S Gero Agents – Agent Societies Common ground for situated communication Common ground = the presuppositions that are taken for granted by an agent to be the shared background of the participants in the conversation established & increased through current and previous communication Common ground a notion subjective to the agent, grounded in its experience a social notion connecting the individually grounded experience to the other participant(s) (different participant(s) => different common ground) Common ground is a means to adapt communication to the specific agent (addressee & speaker)

John S Gero Agents – Agent Societies Common ground supports the generation of representations (messages) for a specific purpose (specific agent with specific knowledge/capabilities) Common ground thus makes communication more efficient than using static object schemas The concept of common ground can be embodied by situated design agents Common ground: A key for agent-based modelling

John S Gero Agents – Agent Societies Situated Creative Designing  Design agents send “artworks” that they find interesting to other agents.  If other design agents find the artwork interesting they send back a an expression of interest.  To be considered creative, design agents have to innovate in ways that other design agents can appreciate.  Design agents that develop the same interests in the space of possibilities form emergent “cliques”.     Emergent society of creative agents ( after Saunders and Gero)
