TAILIEUCHUNG - Báo cáo khoa học: "LIMITED DOMAIN SYSTEMS FOR LANGUAGE TEACHING"

This abstract describes a natural language system which deals usefully with ungrammatical input and describes some actual and potential applications of it in computer aided second language learning. However, this is not the only area in which the principles of the system might be used, and the aim in building it was simply to demonstrate the workability of the general mechanism, and provide a framework for assessing developments of it. BACKGROUND The really hard problem in natural language processing, for any purpose, is the role of non-linguistic knowledge in the understanding process. . | LIMITED DOMAIN SYSTEMS FOR LANGUAGE TEACHING s G Pulman Linguistics EAS University of East Anglia Norwich NR4 7TJ UK. This abstract describes a natural language system which deals usefully with ungrammatical input and describes some actual and potential applications of it in computer aided second language learning. However this is not the only area in which the principles of the system might be used and the aim in building it was simply to demonstrate the workability of the general mechanism and provide a framework for assessing developments of it. BACKGROUND The really hard problem in natural language processing for any purpose is the role of non-linguistic knowledge in the understanding process. The correct treatment of even the simplest type of non-syntactic phenomena seems to demand a formidable amount of encyclopedic knowledge and complex inferences therefrom. To date the only systems which have simulated understanding to any convincing degree have done so by sidestepping this problem and restricting the factual domain in which they operate very severely. In such limited domains semantic or pragmatic processing to the necessary depth can be achieved by brute force as a last resort. However such systems are typically difficult to transpđrt from one domain to another. In many contexts this state of affairs is unsatisfactory - something more than fragile toy domain dependent systems is required. But there are also situations in which the use of language within a limited factual domain might well be all that was required. Second language learning especially during the early stages is one where quite a lot of the time what is important is practice and training in correct usage of basic grammatical forms not the conveying of facts about the world. If someone can be taught to use the comparative construction when talking about say lions and tigers he is not likely to encounter much difficulty of a linguistic nature when switching to talk about cars and buses .
