We can distinguish two different groups of 'fusion expressions' depending on whether the verb (-ko) ha- 'do' can be recovered from the contracted expression concerned or not: recoverable and unrecoverable fusion expressions. Many expressions belonging to the former group show alternations between the [da]-type and the [dae]-type: e.g., o-nta-nta and o-ntae-nta '...says... is coming.' On the other hand, some expressions like ka-ntae can only be realized as the [dae]-type. The main purpose of this paper is to account for these [dae]-type expressions. First, we assume that they have an inaudible/invisible quotation $verb\;{\phi}-$, which takes as its complement a verb phrase with a neutral speech-level ending. This quotation verb is derived from the quotation verb ha-. Second, we assume that the quotation $verbs\;{\phi}-$ and ha- have the [j] sound as their stem-final element, which means that these verbs are actually represented as ${\phi}-j-$ and ha-j-, respectively. In this system, the [tae]-type expressions come out naturally from the behavior of the [j] sound. We do not employ any ad hoc phonological rules to derive the [dae]-type expressions from the corresponding [da]-type expressions.

For the recent several years, there has been much interest in lexical semantic network However it seems to be very difficult to evaluate the effectiveness and correctness of it and invent the methods for applying it into various problem domains. In order to offer the fundamental ideas about how to evaluate and utilize lexical semantic networks, we developed two automatic vol·d clustering systems, which are called system A and system B respectively. 68.455.856 words were used to learn both systems. We compared the clustering results of system A to those of system B which is extended by the lexical-semantic network. The system B is extended by reconstructing the feature vectors which are used the elements of the lexical-semantic network of 3.656 '-ha' verbs. The target data is the 'multilingual Word Net-CoroNet'. When we compared the accuracy of the system A and system B, we found that system B showed the accuracy of 46.6% which is better than that of system A. 45.3%.

Word Sense Disambiguation(WSD) is one of the most difficult problem in Korean information processing. We propose a WSD model with the capability to filter semantic information using the specific characteristics in dictionary dictions, and nth added information, useful to sense determination, such as statistical, distance and case information. we propose a model, which can resolve the issues resulting from the scarcity of semantic information data based on the word hierarchy system (thesaurus) developed by Ulsan University's UOU Word Intelligent Network, a dictionary-based toxicological database. Among the WSD models elaborated by this study, the one using statistical information, distance and case information along with the thesaurus (hereinafter referred to as 'SDJ-X model') performed the best. In an experiment conducted on the sense-tagged corpus consisting of 1,500,000 eojeols, provided by the Sejong project, the SDJ-X model recorded improvements over the maximum frequency word sense determination (maximum frequency determination, MFC, accuracy baseline) of $18.87\%$ ($21.73\%$ for nouns and inter-eojeot distance weights by $10.49\%$ ($8.84\%$ for nouns, $11.51\%$ for verbs). Finally, the accuracy level of the SDJ-X model was higher than that recorded by the model using only statistical information, distance and case information, without the thesaurus by a margin of $6.12\%$ ($5.29\%$ for nouns, $6.64\%$ for verbs).

The purpose of this paper is to build a semantic networks of the 'cooking class' verb (based on 'CoreNet' of KAIST). This proceedings needs to adjust the concept classification. Then sub-categories of [Cooking] and [Foodstuff] hierarchy of CoreNet was adjusted for the construction of verb semantic networks. For the building a semantic networks, each meaning of 'Cooking verbs' of Korean has to be analyzed. This paper focused on the Korean 'heating' verbs and 'non-heating'verbs. Case frame structure and argument information were inserted for the describing verb information. This paper use a Propege 3.3 as a tool for building "cooking verb" semantic networks. Each verb and noun was inserted into it's class, and connected by property relation marker 'HasThemeAs', 'IsMaterialOf'.

본고는 한국어의 양화사 유동 현상을 일반범주문법의 관점에서 통사론적, 의미론적으로 분석한다. '학생들이 넷이 술을 마셨다' 와 같은 문장에서 나타나는 유동 양화사는 통사론적으로 동사구수식어 (VP/VP)로 파악하고, 의미론적으로는 명사화된 속성이 관여하는 것으로 분석한다. 이 밖에도, 관련된 형태인 '넷' (NP/NP), '넷을' (TV/TV)등도 엄밀한 통사론적, 의미론적 분석을 시도한다. 성공적인 분석의 결과는 한국어 처리에 인접성 조건을 준수하는 범주문법의 사용가능성을 시사해 준다.

To build a Korean wordnet, we translated semi-automatically the English wordnet PWN into Korean verbs. During this process, we found that some of translation errors are related to the arbitrariness of PWN`s sense distinction in regard to the accusativity/inaccusativity of the same verb form in English. This study presents an empirically based method of remodeling the PWN for Korean wordnet and while revising the PWN`s hierarchical structure, it shows the necessity of classifying the Korean passive verbs as semantically autonomous.

한일 양언어의 복합문은 여러가지의 통어 현상을 가지며, 주어, 목적어 등의 생략 현상으로 문장의 표층상에 나타나지 않는 것이 있기 때문에 수식구조의 처리가 복잡해지고, 구문해석에 있어서 애매성의 요인이 된다. 따라서, 본 논문에서는 DPN에 의하여 한국어와 일본어의 수식 scope를 해석하는 방법에 대하여 설명한다. 먼저, 한일 양언어의 공통점과 차이점을 찾아내어, 한국어와 일본어의 보문을 표현형식으로 나타내고, 동사의 격정보로부터 DPN을 구성하여 DPN상에서 보문의 수식 Scope를 해석하는 방법에 대해서 설명한다.

MS-DOS 명령을 대신하는 자연어 인터페이스를 연구하였다. 자연어로 입력되는 한국어 문장을 형태소분석, 구문분석, 의미분석, 개념분석을 통해 대응되는 일련의 MS-DOS 명령을 생성한다. 형태소 분석에서는 Tabular Parsing법을 사용하였고, 구문분석에서는 문법적인 수식-피수식 관계를 확대하여 의미상의 수식-피수식 관계를 설정하고 이에 따라 문장을 몇개의 단위로 나눈다. 의미분석에서는 동사와 이들 단위들간의 관계와 단위를 구성하는 어절들간의 관계를 격관계로 설정하여, 개념망(semantic network)으로 문장의 의미를 표현한다. 이 개념망으로부터 MS-DOS 명령을 생성한다.
