An Endorsement-based Plan Recognition Program
نویسندگان
چکیده
This paper describes a plan-recognition program built to explore the theory of endorsements (Cohen, 1983). The program evaluates alternative interpretations of user actions and reasons about which are the most likely explanation of the user's intentions. Uncertainty about the various alternatives was encoded in data structures called endorsements. The paper describes the workings of this program and the successes and limitations of the endorsement-based approach. endorsements. The next section describes a plan recognition program that uses endorsements to reason about the uncertainty in interpreting user actions. We then discuss some of the problems we encountered in implementing this program, problems which highlight some of the key issues involved in dealing wi th

Alert correlation and prediction using data mining and HMM
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...

متن کاملLearning Plan Schemata From Observation: Explanation-Based Learning for Plan Recognition
This article discusses how explanation-based learning of plan schemata from observation can improve performance of plan recognition. The GENESIS program is presented as an implemented system for narrative text understanding that learns schemata and improves its performance. Learned schemata allow GENESIS to use schema-based understanding techniques when interpreting events and thereby ovoid the...
