A flexible parser can deal with input that deviates from its grammar, in addition to input that conforms to it. Ideally, such a parser will correct the deviant input: sometimes, it will be unable to correct it at all; at other times, correction will be possible, but only to within a range of ambiguous possJbilities. This paper is concerned with such ambiguous situations, and with making it as easy as possible for the ambiguity to be resolved through consultation with the user of the parser - we presume interactive use. . | H uuiibirucuon-opeciTic Approacn to Focused Interaction in Flexible Parsing Philip J. Hayes Carnegie-Mellon University Pittsburgh PA 15213 Abstract1 A flexible parser can deal with input that deviates from its grammar in addition to input that conforms to it. Ideally such a parser will correct the deviant input sometimes it will be unable to correct it at all at other times correction will be possible but only to within a range of ambiguous possibilities. This paper is concerned with such ambiguous situations and with making it as easy as possible for the ambiguity to be resolved through consultation with the user of the parser - we presume interactive use. We show the importance of asking the user for clarification in as focused a way as possible. Focused interaction of this kind is facilitated by a constructionspecific approach to flexible parsing with specialized parsing techniques for each type of construction and specialized ambiguity representations for each type of ambiguity that a particular construction can give rise to. A construction-specific approach also aids in task-specific language development by allowing a language detinition that is natural in terms of the task domain to be interpreted directly without compilation into a uniform grammar formalism thus greatly speeding the testing of changes to the language definition. 1. Introduction There has been considerable interest recently in the topic of flexible parsing . the parsing of input that deviates to a greater or lesser extent from the grammar expected by the parsing system. This interest springs from very practical concerns with the increasing use of natural language in computer interfaces. When people attempt to use such interfaces they cannot be expected always to conform strictly to the interface s grammar no matter how loose and accomodating that grammar may be. Whenever people spontaneously use a language whether natural or artificial it is inevitable that they will make errors of .
