It uses a hybrid, modular knowledge representation, a so called geometric tree being its essential part. This tree is used to perform a best-first search in combination with a \"hypothesize & test\"strategy. It produces an internal, editable description of the entire document and its constituents. The system has been implemented for the analysis of single-sided business letters in Common Lisp on a SUN 3!60 Workstation. It is running for a large population of different business letters. The results obtained have been very encouraging and have convincingly confirmed the soundness of the approach.","doi":null,"url":"https://ijcai.org/proceedings/1989/200","pdf":"https://ijcai.org/proceedings/1989/0200.pdf","markdown":"https://ijcai.org/proceedings/1989/200.md","bibtex":"https://ijcai.org/proceedings/1989/bibtex/200","volume":{"slug":"1989","title":"Proceedings of the Eleventh International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1989","url":"https://ijcai.org/proceedings/1989/","year":1989,"location":"Detroit, Michigan, USA","dates":"August 20-25 1989","editors":"N.
