In this paper we present some novel ap- plications of Explanation-Based Learning (EBL) technique to parsing Lexicalized Tree-Adjoining grammars. The novel as- pects are (a) immediate generalization of parses in the training set, (b) generaliza- tion over recursive structures and (c) rep- resentation of generalized parses as Finite State Transducers. A highly impoverished parser called a "stapler" has also been in- troduced. We present experimental results using EBL for different corpora and archi- tectures to show the effectiveness of our ap- proach.
