Expressing such potential caveats is a difficult process due to the many potential plan failures for each particular plan in a particular planning situa- tion. A commonsense planner, called KIP, Knowledge Inten- sive Planner, is described. KIP is the planner for the UNIX Consultant system. KIP detect potential plan failures using a new knowledge structure termed a concern. Concerns allow KIP to detects plan failures due to unsatisfied conditions or goal conflict. KIP's concern algorithm also is able to provide information to the expression mechanism regarding potential plan ...
