Situated Cognition

Analysis: There are benefits to being able to visualize a network as more than a directed graph, even though a graph representation is computationally powerful.

Foreshadowing augmented reality notions, Clancey defined “situated cognition” as

. . . viewed not just in terms of high-level “expertise,” but in the ability to find one’s way around the world, to learn new ways of seeing things, and to coordinate activity. This approach is called situated cognition.

Enterprise Rule Groups: Policies

Analysis: Policies are essentially rule groups. Rules are typically implemented using non-reusable reasoning engines that are rarely given that designation. This paper suggests advantages of certain rule aggregations.

We explain how network administration can be simplified by defining two levels of policies, a business level and a technology level. We discuss how business-level policies are validated and transformed into technology-level policies, and present some algorithms that can be used to check for policy conflicts and unreachable policies
