For Readers Already Familiar with Cognitive Architectures

Of primary interest to the reader already familiar with cognitive architectures will be contextual links(*) between nodes. These links demonstrate the relationship between the motivation for a particular architecture, the architecture itself, properties of a particular architecture, its resulting capabilities, the environments in which it does (and does not) function and general issues relating to all architectures. For instance, the discussion of frames for the Theo architecture includes contextual links relating frames to Theo's utilization of meta-knowledge and an impasse-driven control strategy. The former then suggests that meta-knowledge is used to realize meta-reasoning and self-reflection in Theo while the latter demonstrates that frames and the impasses defined in relation to frame slots allow focused behavior in Theo. Thus, the use of contextual links makes the relationship between different facets of the architecture explicit. We believe that the framework we use for developing these relationships and their explicit identification constitutes a contribution to the field of agent and cognitive architectures.

*: The terms node, link, document, contextual, and non-contextual are defined in a separate node.
