The s y stem is designed to process the text of handprinted formal languages, such as programming languages and mathematical notation. The system is syntax-directed in that a contextual processor for a particular language is constructed by a one-time, algorithmic analysis of the language grammar. The resulting analysis engine massages the classifier output by successive vocabulary matching, namespacet clustering, and syntactic analysis to produce as output a syntactically valid interpretation of the text, with as many errors corrected as possible. A more complete description of the system can be found in Darden.","doi":null,"url":"https://ijcai.org/proceedings/1969/52","pdf":"https://ijcai.org/proceedings/1969/0052.pdf","markdown":"https://ijcai.org/proceedings/1969/52.md","bibtex":"https://ijcai.org/proceedings/1969/bibtex/52","volume":{"slug":"1969","title":"Proceedings of the First International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1969","url":"https://ijcai.org/proceedings/1969/","year":1969,"location":"Washington, DC, USA","dates":"May 7-9, 1969","editors":"Donald E.
