Two different instantiations of the GRAELenvironment are described in this paper: in GRAEL1 large annotated corpora are used to bootstrap grammatical structure in a society of agents, who engage in a series of communicative attempts, during which they redistribute grammatical information to reflect useful statistics for the task of parsing. In GRAEL-2, agents are allowed to mutate grammatical information, effectively implementing grammar rule discovery in a practical context. A combination of both GRAEL-1 and GRAEL-2 can be shown to provide an interesting all-round optimization for corpus-induced grammars.","doi":null,"url":"https://ijcai.org/proceedings/2003/119","pdf":"https://ijcai.org/proceedings/2003/0119.pdf","markdown":"https://ijcai.org/proceedings/2003/119.md","bibtex":"https://ijcai.org/proceedings/2003/bibtex/119","volume":{"slug":"2003","title":"Proceedings of the Eighteenth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2003","url":"https://ijcai.org/proceedings/2003/","year":2003,"location":"Acapulco, Mexico","dates":"","editors":"Georg Gottlob","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":null,"track":"","number":119,"pages":{"first":823,"last":831},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
