Despite these advances , the quality of prose produced by explanation generators warrants significant improvement. Revision-based explanation generation offers a promising means for improving explanations at runtime. In contrast to singledraft exp lanation generation architectures, a revision-based generator could dynamically create, evaluate, and refine multiple drafts of explanations. However , because of the inherent complexity of revision , previous multisentential revision-based approaches have not scaled up . We have developed a scalable revision-based model of explanation generation that dynamically improves multi-sentential explanations. By operating on abstract discourse plans encoded in a minimalist representation, it combats both the conceptual complexities and the efficiency problems posed by revision . This approach has been implemented in REVISOR, a unification-based revision system. Evaluations of REVISOR's performance in generating a corpus of extended multi-sentential scientific explanations yielded encouraging results.","doi":null,"url":"https://ijcai.org/proceedings/1997/137","pdf":"https://ijcai.org/proceedings/1997/0137.pdf","markdown":"https://ijcai.org/proceedings/1997/137.md","bibtex":"https://ijcai.org/proceedings/1997/bibtex/137","volume":{"slug":"1997","title":"Proceedings of the Fifteenth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1997","url":"https://ijcai.org/proceedings/1997/","year":1997,"location":"Nagoya, Japan","dates":"","editors":"Martha E.
