This paper introduce a Koran-Japanese machine translation system which is a module in the spoken language interpreting system It is implemented based on the TDMT(Transfre Driven Machine Translation). We define a new unit of translation so called TOKEN. The TOKEN-based translation method resolves nonstructural feature in Korean sentences and increases the quaity of translating results. In our system, we get rid of useless effort for traditional parsing by performing semi-parsing. The semi-parser makes the dependency tree which has minimum information needed generating module. We constructed the generation dictionaries by using the corpus obtained from ETRI spoken language database. Our system was tested with 600 utterances which is collected from travel planning domain The success-ratio of our system is 87% on restricted testing environment and 71% on unrestricted testing environment.

Korean and Japanese have same structure of sentences because they belong to same family of languages. So, The transfer driven machine translation is most efficient to translate each other. This paper introduce a method which creates a transfer dictionary for Token Based Transfer Driven Koran-Japanese Machine Translation(TB-TDMT). If the transfer dictionaries are created well, we get rid of useless effort for traditional parsing by performing shallow parsing. The semi-parser makes the dependency tree which has minimum information needed output generating module. We constructed the transfer dictionaries by using the corpus obtained from ETRI spoken language database. Our system was tested with 900 utterances which are collected from travel planning domain. The success-ratio of our system is $92\%$ on restricted testing environment and $81\%$ on unrestricted testing environment.

In the transfer machine translation, transfer dictionary decides the complexity of the transfer phase and the quality of translation according to the types and precision of informations supplied in the dictionary. Using the phrasal level translated informations within the human readable dictionary, human being translates a source sentence correctly and naturally. In this paper, we propose the verb transfer dictionary in which the various informations are constructed so the machine readable format that the Korean-to-English machine translation system can utilize them. In the proposed dictionary, we first provide the criterions by which an appropriate target verb is selected in phrase-to-phrase translations without an additional semantic analysis in transfer phase. Second, we provide the concrete sentence structure of a target verb so that we can resolve the expressive gaps between two languages and reduce the complexity of the various structure transfer in word-to-word translation.

대부분 자연 언어 이해 시스템이나 중간 언어 방식을 이용한 기계 번역 시스템에서 자연 언어 문장을 이해하고 번역하기 위해서는 대량의 지식을 이용한 의미 구조의 생성이 요구된다. 따라서 개념 그래프를 이용하여 한국어 문장의 내부 의미 구조를 생성하기 위해서는 각 단어에 해당하는 개념과 개념들 사이의 개념적 관계를 나타내는 지식들이 요구된다. 그러나 이를 위한 의미 구조 생성 방법과 요구되는 지식 베이스를 정확하게 구축하는 것은 어렵고 응용 도메인에 종속한다는 문제가 있다. 본 논문에서 우리는 문형 이론을 도입하여 문형을 중심으로 의미 구조 생성을 위한 변환 규칙을 설계하고 이를 이용하여 방대한 지식 베이스의 구축없이 의미 구조를 생성할 수 있는 방법에 논의한다. 또한 본 논문에서 문형을 이용하면 몇 가지 모호성 문제를 해결할 수 있음을 보이고 문형의 한계에 대해서도 살펴본다.
