This website provides resources and information related to SOSIEL (Self-Organizing Social & Inductive Evolutionary Learning) - a rapidly-developing theory for representing human behavior in social contexts. The SOSIEL framework, a set of methods that support it, a cognitive multi-agent knowledge-based platform for simulating SOSIEL behavior, and another framework describing the double-boundedness of agent rationality comprise the SOSIEL Toolkit. The website also provides links to examples of models built or coupled with the SOSIEL Platform. Please contact us with any feedback or suggestions.
