Focusing in Plan Recognition
نویسندگان
چکیده
A plan recognition architecture is presented which exploits application-specific heuristic knowledge to quickly focus the search to a small set of plausible plan interpretations from the very large set of possible interpretations. The heuristic knowledge is formalized for use in a truth maintenance system where interpretation assumptions and their heuristic justifications are recorded. By formalizing this knowledge, the system is able to reason about the assumptions behind the current state of the interpretations. This makes intelligent backtracking and error detection possible.

Situated Plan Attribution1
Plan recognition techniques frequently make rigid assumptions about the student's plans, and invest substantial effort to infer unobservable properties of the student. The pedagogical benefits of plan recognition analysis are not always obvious. We claim that these difficulties can be overcome if greater attention is paid to the situational context of the student's activity and the pedagogical ...

Intrusion Detection Systems (IDSs) are security tools widely used in computer networks. While they seem to be promising technologies, they pose some serious drawbacks: When utilized in large and high traffic networks, IDSs generate high volumes of low-level alerts which are hardly manageable. Accordingly, there emerged a recent track of security research, focused on alert correlation, which ext...
