چکیده

Plan recognition does not work the same way in stories and in "real life, (people tend to jump to conclusions more in sto­ ries). We present a theory of this, for the particular case of how objects in stories (or in life) influence plan recognition decisions. We provide a Bayesian network formaliza­ tion of a simple first-order theory of plans, and show how a particular network param­ eter seems to govern the difference between "life-like" and "story-like" response. We then show why this parameter would be in­ fluenced (in the desired way) by a model of speaker (or author) topic selection which assumes that facts in stories are typically "relevant".
