Responding To Semantically Ill-Formed Input
نویسندگان
چکیده
One cause of failure in natural language interfaces is semantic overshoot; this is reflected in input sentences which do not correspond to any semantic pattern in the system. We describe a system which provides helpful feedback in such cases by identifying the "semantically closest" inputs which the system would be able to understand.

Understanding Pragmatically Ill-Formed Input
An utterance may be syntactically and semantIcally well-formed yet violate the pragmatic rules of the world model. This paper presents a context-based strateEy for constructing a cooperative but limited response to pragmatlcally illformed queries. Sug~estlon heuristics use a context model of the speaker's task inferred from the preceding dialogue to propose revisions to the speaker's ill-formed...
متن کاملMeta-Rules as a Basis for Processing III-Formed Input
If natural language processing systems are ever to achieve natural, cooperative behavior, they must be able to process input that is i l l-formed lexically, syntactically, semantically, or pragmatically. Systems must be able to partially understand, or at least give specific, appropriate error messages, when input does not correspond to their model of language and of context. We propose meta-ru...
متن کاملSchema method: a framework for correcting grammatically ill-formed input
The schema method is a framework for correcting grammatically ill-formed input. In a natural language processing system ill-formed input cannot be overlooked. A computer assisted instruction (CAD system, in particular, needs to show the user's errors. This framework diagnoses ill-formed input, corrects it and explains the error, if an input is ill-~'ormed. The framework recognizes a sentence at...
متن کاملA Rule-Based Approach To Ill-Formed Input
Though natural language understanding systems have improved markedly in recent years, they have only begun to consider a major problem of truly natural input: ill-formedness. Quite often natural language input is ill-formed in the sense of being misspelled, ungrammatical, or not entirely meaningful. A requirement for any successful natural language interface must be that the system either intel...
متن کاملReflections on the Knowledge Needed to Process Ill-Formed Language
This paper reflects about the kinds of morphological, syntactic, semantic, and pragmatic knowledge needed to process ill-formed input. We conclude that an excellent start on processing ill—formed input has been exemplified in a number of concrete implementations, but that a substantial amount of fundamental work must still be done if our systems are to understand language robustly to the degree...
