</SectionTitle>
    <Paragraph position="0"> Ill-formed input cannot be ignored by natural language processing systems. This paper has suggested a uniform framework for processing ill-formed input in the hope of providing a basis for standardizing work on ill-formedness.</Paragraph>
    <Paragraph position="1"> Our framework has several advantages: a) Well-formed interpretations are always preferred. b) Ill-formedness processing is explicitly related to the well-formedness rules.</Paragraph>
    <Paragraph position="2"> c) Only the constraint that seems to be violated is relaxed; all other well-formedness constraints are still effective for eliminating senseless interpretations and trimming search.</Paragraph>
    <Paragraph position="3"> d) Deviance notes record the aspect that deviates from well-formedness, thus allowing pragmatic inferences by later processing.</Paragraph>
    <Paragraph position="4"> e) Though our approach is uniform, it permits encoding as much specific knowledge into the diagnosis and recovery procedure as one desires for highly specialized cases.</Paragraph>
    <Paragraph position="5"> f) Though this paper has drawn most of its examples from ATN grammars and from case frame processing, as argued in Section 3.3., the framework is not dependent on a particular model of language processing. null g) The framework should be applicable to lexical, syntactic, semantic, and pragmatic constraints.</Paragraph>
