摘要: 以往的规划识别中忽略了误导动作,导致一些特定领域中规划识别的准确度不高。为了解决该问题,该文引进了置信度、相关关系、相关动作序列等新概念,给出了一种根据相关动作序列置信度的计算结果,来判断规划识别中已观察动作是否为误导动作的算法。该算法的提出增强了规划识别的准确度,在入侵检测、网络安全等方面有着很好的应用前景。

Abstract: The omitting of misleading actions in the research of previous plan recognition leads the result of recognition in low accuracy in some special domains. In order to solve this problem, new concepts are defined, such as reliability, correlativity, and correlated action sequence etc. And a novel algorithm is proposed to determine whether the action is misleading action or not. It makes use of the results worked out by correlated action sequences. The new algorithm improves the accuracy of plan recognition. Moreover, the prospect of the application of the algorithm is bright in intrusion detection, network security and other domains.
