Classification of utterances concerning speaker's meaning. DPs present background information of language use in order to derive an appropriate expression from speaker's meaning. In Japanese, IFTs can be derived a u t o m a t i c a l l y t h r o u g h syntactical constraints. To generate appropriate expressions, language-specific communication strategies related to DP values should be given a priori. The whole process is performed in a unification-based framework. | A Descriptive Framework for Translating Speaker s Meaning - Towards a Dialogue Translation System between Japanese and English - Masako KUME Gayle K.

IFTs are a certain kind of classification of utterances concerning speaker s meaning. DPs present background information of language use in order to derive an appropriate expression from speaker s meaning. In Japanese IFTs can be derived automatically through syntactical constraints. To generate appropriate expressions language-specific communication strategies related to DP values should be given a priori. The whole process is performed in a unification-based framework. 1. Introduction In devising a machine translation system of telephone dialogues one of the problems is how to adequately translate the underlying meaning of the source utterance or the speaker s intention into the target language. Such a concern is rarely observed in conventional machine translation research which has focused on strictly grammatical translation divorced from consideration of the speaker s situation and intentions Tsujii and Nagao 1988 . However in dialogue smoothness of communication depends on perceiving the speaker s intention. Especially when dealing with different language family pairs such as Japanese and English it is necessary to have a methodology of treating language-specific communication strategies in a universal framework. Although the input of our machine translation system is spoken dialogue here we leave aside the issues of speech processing and limit our discussion to linguistic processing. Extra-grammatical sentence patterns such as intra- .
