Delaying commitment in plan recognition using combinatory categorial grammars
Christopher Geib · 2009
This paper presents a new algorithm for plan recog-nition called ELEXIR (Engine for LEXicalized In-tent Recognition). ELEXIR represents the plans to be recognized with a grammatical formalism called Combinatory Categorial Grammar(CCG). We show that representing plans with CCGs can allow us to prevent early commitment to plan goals and thereby reduce runtime. 1
