Title Semantic Construction From Parse Forests
Venue International Conference on Computational Linguistics
Session Main Conference
Year 1996

The paper describes a system which uses packed parser output directly to build semantic representations. More specifi- cally, the system takes as input Packed Shared Forests in the sense of Tomita (l_bmita, 1985) and produces packed Underspeeified Discourse Representation Structures. The algorithm visits every node in the Parse Forest only a bounded number of times, so that a significant in- crease in efficiency is registered for am- biguous sentences.
