Handling Ill-Formed Input: Session Introduction,
Abstract
This session consists of papers by Jensen and Heidorn; Marsh; and Granger et al. The paper by Jensen and Heidorn presents a particular heuristic for dealing with unparsable input. Since they have separate explicit heuristics for specific ungrammatical forms, a significant proportion of unparsable input in their system will be relatively ill-formed. Marsh's paper describes a technique for filling in material omitted from fragmentary inputs. Both syntactic information and domain-specific constraints on semantic classes are used. The paper by Granger et al. reports on NOMAD, a system for taking cryptic, errorful naval ship-to-shore messages and generating well-formed versions. The paper describes the methods used for processing unknown words, fragments, missing punctuation, and tense errors.
