Another powerful formalism for describing natural languages follows from a method for expressing grammars in logic, due to Colmerauer (1978) and Kowalski (1974) called definite clause grammars (DCG) (Warren, Pereira, 1 980) . Both formalisms are a naturalexte nsion o f context free grammars (CFG) . The aim of this paper is to show - how LPG ca n be translated into DCG that the procedural semantics of PROLOG provides an eff icient tool for LFG-implementations in that it allows the construction of function structures (f-structures) directly during the parsing process . I.e . it is not necessary to have a separate component which first derives a set of functional equations from the parse tree, and second ly generates a f-structure by solving these eq uations.","doi":null,"url":"https://ijcai.org/proceedings/1983/167","pdf":"https://ijcai.org/proceedings/1983/0167.pdf","markdown":"https://ijcai.org/proceedings/1983/167.md","bibtex":"https://ijcai.org/proceedings/1983/bibtex/167","volume":{"slug":"1983","title":"Proceedings of the Eighth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1983","url":"https://ijcai.org/proceedings/1983/","year":1983,"location":"Karlsruhe, West Germany","dates":"","editors":"Alan Bundy","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":"Natural Language","track":"Natural Language","number":167,"pages":{"first":693,"last":694},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
