Parsing speech, having to process a lattice of word hypotheses instead of a string of words, involves a tremendous amount of search and the generation of a high number of phrase hypotheses. The aim is, while using powerful and flexible formalisms for syntax and semantics, to generate \"compact\" phrase hypotheses, each one accounting for many syntactic rules simultaneously. The proposed method is able to cope with, and to take advantage from, the fact that short words are often missing from the lattice. A detailed example is given to clarify this method. Finally experimental data are presented and discussed, showing the effectiveness of the proposed technique.","doi":null,"url":"https://ijcai.org/proceedings/1991/144","pdf":"https://ijcai.org/proceedings/1991/0144.pdf","markdown":"https://ijcai.org/proceedings/1991/144.md","bibtex":"https://ijcai.org/proceedings/1991/bibtex/144","volume":{"slug":"1991","title":"Proceedings of the Twelfth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1991","url":"https://ijcai.org/proceedings/1991/","year":1991,"location":"Sydney, New South Wales, Australia","dates":"24-30 August 1991","editors":"John Mylopoulos and Ray Reiter","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":"Natural Language","track":"Natural Language","number":144,"pages":{"first":979,"last":984},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
