The generating method of syntax analyzer using production language (PL) developed by Evans [1] is efficient method, but it's very difficult to construct PL. So, this paper deals with algorithm generating PL from given BNF ALGOL grammar.

속성에 할당된 새로운 조건을 통해 평가를 수행할 때 이미 산출된 부분을 재사용하기 위해서는 새로운 평가방법이 필요하다. 이 논문에서는 평가된 속성 값의 전파를 고려한 최적화 알고리즘을 제안하는 기존 속성 트리의 서브 트리와 새로운 속성 트리의 서브 트리를 비교하여 전파되는 속성 값과 노드가 일치할 경우 기존 속성 트리의 서브 트리를 새로운 속성 트리에서 사용이 가능한 최적화된 알고리즘을 제안하고 평가하였다.

본 연구에서는 전자상거래 데이터베이스를 대상으로 결합범주문법을 이용한 자연언어질의 인터페이스를 구현한다. 이를 위해 질의문을 분석하고 표현 방법을 논의한다. 또한 SQL 형식언어로 변환하기 위한 어휘 표현 및 유도 방법을 보인다. 제안하는 방법은 구문분석 과정에서 SQL 형식의 질의문을 직접 유도하는 것으로 기존 연구에서 제안됐던 중간논리언어 변환단계를 거치지 않으므로 과정이 간결해져 시스템의 성능향상을 가져올 수 있다. 시스템은 웹 기반과 client/server 구조로 구현된다.

The issues concerning the nature of the attitude toward the study of national language may vary from country to country, depending on the national or racial characteristics. The problem domains and the methodologies dealing with them may vary accordingly. Ever since the Korean language was equipped with a writing system in the year of 1443 through King Sejong's long-cherished desire, investigations have been constantly made into the real nature of the language itself in pursuit of a better method for representing the spoken language in written form. This is how the study of the Korean language began to take shape. Among such investigations are Hunmin-jeong-eum(the Korean script: 1446) compiled by Jiphyon-jon, the royal office of schloarly researches, Doongguk-jeonghun-yokhun (the orthodox script of Korean: 1448), Hongmu-jeonghun-yeokhun(interlinear gloss for the Chinese script of the Ming Dynasty: 1455), An Orthodox Approach to Written Korean (1909) by the institute of the National Script, Re Standardized Spelling System (1933) by Chosun Language Society, An Authorized Dictionary of Standard Korean (1936), How to Write Borrowed Words(1940), and A Grand dictionary of Korea (1947-57). Chu Shi-Gyung's Phonetics of the Korean Script(1908), Korean Grammar(1910), and Sound Patterns of Korean(1914) were all written in this vein; so was Choi Hyun-Bae's Uri-mal-bon (the rudiments of Korean Grammar: 1929/1937). All these achievements in the study of the Korean language are the end-products of the constant endeavor to solve the issues related to the spoken and written farms of the Korean language. And this is how the uniqueness and autonomy of the language study in korea have been established. It should be borne in mind, however, that, in seeking solutions to the problems inherent in the Korean linguistic studies of foreign countries. On the contrary, they have been very active in accommodating such results. While they have set up their problem domains on the basis of the korean language, they been progressively open-minded in looking for the solutions to the problems at hand.

For the effective study of Korean modernization from the 18th century to the present, three areas have been investigated in my paper: the age of dawn in recognizing the necessity of modernism, the era of experimentation from recognition to practice, and the development of modernism in literature: from the 1930s to the present. Through whole process of discussing those matters, Koreanity- identifying itself to be Korean - has been emphasized. While the so-called traditional values confronted with the whole turmoil of socio-political demolitions in the name of modernization, westernization, and culturalization, Korean intellectuals tried to emphasize how important it was to keep Korean identities, namely the Koreanity. Such examples can be seen in the activities of Northern School and Moderate School. Though Koreans had to have a short hair cut in contradiction with their traditional morality to be modernized/westernized/cultivated, it was a turning point for them to take a step toward the international world. During the period of Korean modernization through the impact of Western world, Korean language-hangul- has been cultivated to the highest level in comparison with two foreign languages: Japanese and English. Those Korean linguists who were familiar with these two languages made Korean grammar systematic and they understood the importance of preserving Koreanity in the course of pursuing modem western society. In this sense, Korean modernism is related to the cultural glocalism(globalism+ localism), not to the cultural globalism. Through the help of socio-political modernization, Korean literature in modernism has been full bloomed in the early years of 1930s. One of the leading poets was Sang Lee whose poetic heritage is inherited by those groups of 1950s and I 960s. Among many others, Chunsu Kim and Sunghun Lee were the main figures in realizing the fact the poetry is written in Korean which they considered the body, the soul, and the mother land.

A parallel communicating automata system is an accepting device based on the communications between more automata working in parallel. It consists of several automata corking independently but communicating with each other by request. We survey several variants of parallel communicating automata systems with respect to their computational power. Other aspects like decidability and complexity matters are also briefly discussed. Some open problem sand directions for future research are finally pointed out.

This paper analyzes succinct graph descriptions and its complexity of connectivity problems on context free graph languages under various restrictions. It defines SNLC(Simple Context Free Node Label Controlled) grammar and presents reduction method that solves graph problems without expanding the hierarchical description. It exemplifies the method by giving efficient solutions to connectivity problems on graphs and presents parallel algorithm for reduction and analyzes the complexity. Its results will help application of desing for NETWORK. CAD. VLSI and other engineering problems.

본 논문의 목적은 매개변항(parameter)과 부분집합원리(subset principle)를 재귀대명사 구조분석 및 습득에 적용하여 보편문법(Universal Grammar)과 언어습득의 상호관계를 검토하는 데에 있다. 본 논문은 첫째, 재귀대명사 '자기'를 매개변항이론에 근거하여 분석하고, 둘째, 재귀사의 구조를 부분집합원리에 적용하여 '자기'의 습득과정을 관찰한다. 본 논문의 목적을 위해 두 가지 가설을 세워 실험적으로 검증하였다. 실험결과, 선행사자격 습득단계의 가설이 확증되었으며, 지배변항 습득단계의 가설은 결정적 증거가 미비해 앞으로의 과제로 남아 있다.

본 논문에서는 한국어의 전산처리를 위한 문법 모형 개발의 일부분으로 HPSG에 기반한 문법 모형의 개발을 시도한다. 문법 모형의 개발에는 ALE(Attribute Logic Engine)를 이용하며, 보문 구조와 보조 용언 구문을 분석하기 위한 사전구조 및 문법 규칙을 제시한다. 그리고 문의 종류 (Sentence Type:ST)와 문계(Sentence Level: SL), 시제, 존대 등을 분석해서 표상하기 위한 유형 계층 및 어휘부, 문법 규칙, 문법 원리 등을 제시한다.

This paper discusses mixed agreement triggered by hybrid pronouns. Hybrid pronouns considered in this paper show number discrepancy in that they are plural in form but singular in meaning. When predicates agree with these hybrid pronouns, the puzzle of number agreement arises: finite verbs show syntactic agreement, while predicate adjectives show semantic agreement. This is explained by three factors in grammar of agreement, the feature specification of agreement controllers, the types of agreement targets, and the Agreement Marking Principle that mediates the relation of two poles of agreement, controllers and targets.
