The problem whether a given grammar G generates an LL language or not is investigated in respect of LL transformable grammars. The previous work involves a nondeterministic intricated parser construction for the characterization of LL transformable grammars. The method hence does not give the intuitive understanding of the essence of LL languages. This paper suggests a characterization of LL transformable grammars based on grammatical derivations instead of the complicated parser construction. The new characterization contributes to intuitive understanding of the essence of LL languages.

This study is to examine grammar understanding with beginner English speakers according to presentational methods of grammatical content. 18 English-speaking Korean beginners were randomly assigned and divided into two groups. We first examined if there was a statistically significant difference between the two groups in grammar comprehension with and without illustrations. It was found that the group given the presentation illustrations showed greater understanding than the group without them. Second, no statistically significant difference in grammar understanding was found between the groups with and without materials marked for their awareness. Third, no statistically significant difference was found between the groups with the order of presenting content elements related to grammatical items. This study is to affirm the importance of illustrations as a component of Korean textbooks.

An attribute grammar is a set of semantic rules added to the syntax rules. This attribute grammar uses two attributes. It is difficult to write by its additional rules to the existing syntax rules with two attributes understanding the parsing steps. So this paper analyses attributes and an attribute grammar to construct the attribute grammar easily proposing three definitions and shows a possibility that an attribute grammar can be written with only one attribute in some cases.

인간과 컴퓨터의 대화(interaction)에 있어서 가능하다면 인간이 쓰는 언어로 인간이 원하고자 하는 소정의 작업을 지시하고 그 출력을 제공받을 수 없을까하는 목표를 두고 세계각국이 모국어의 컴퓨터처리 이론 및 알고리즘개발에 열중하고 있다. 이 논문은 우리의 국어인 한글을 컴퓨터가 처리하는 지적처리를 목표로, 연구중인 한글 이해 시스팀의 구축을 위한 이론과 그 처리 알고리즘에 대해서 논하고 있다. 구체적으로는 최신의 이론언어학의 문법이론을 도입하여 국어의 언어현상에 대한 형식화 모델을 제시하고 있다. 우리의 모델은 각각의 이질적인 언어현상에 대한 지식을 통일적 지식표현과 그 이용법을 체계적으로 기술하고 있다. 그 결과 우리의 접근법이 세계 어느 언어권의 형식화 수준보다 선진하고 있음을 제시한다.

Today, art education needs education of media image production or media in the extended field. The purpose of this study is to develop the basic visual grammar and communication ability. We developed and applied the teaching plan for the interview video production as the fusion lesson. 3 classes were conducted for 30 middle school students. The results obtained through the analysis of the pre & post questions and student works are as follows. First, the students used the shot size and stable composition through the interview video production. As a result, this class was effective for the acquisition of the basic video grammar. Second, students improved their ability to ask and listen, understand and organize through interview. As a result, students were able to apply the basic video grammar through the interview video production lesson, effectively producing the interview image.

One of the methodologies for the type-checking of an expression is the attribute grammar. But this attribute grammar is difficult to write because two attributes should be used with the full understanding of parsing steps. So this paper proposes a methodology to construct an expression attribute grammar easily. It shows the possibility to check the type of an expression with only one attribute through a grammar construction method.

본고는 텍스트로 제시된 한국어 문장의 형태통사론적 오류와 의미적 논항결합시 하위범주화요건을 위배하는 논항선택 오류의 인식 및 판단에 따른 ERP(Event-Related Potential)를 검출하여, 이에 대한 문장이해과정의 시간추이적 양상을 연구의 대상으로 하였다. 참여한 피험자로부터 각각의 유형에 대한 통계분석 결과, 통사적 오류 추출에서 의미적 오류 추출에 이르기까지 기존의 연구에서 제시된 오류패턴 요소들(ELAN, N400, P600)을 확인하였으며, 아울러 한국어 문장이해과정의 특이성을 관찰할 수 있었다. 이를 통해 문장묵독시 일어나는 여러 종류의 문법오류에 대한 개별적 성격규명과 함께, 이들의 문법틀 내에서의 상호관계에 대한 일련의 가설설정이 이루어질 수 있으며, 또한 문장이해 메커니즘의 신경적 기전의 특성 규명으로 부수될 인간지능 모사가능성에 생리학적 토대가 더해 질 것으로 추정되는 바, 언어이해와 대뇌기전지형을 결정짓는 또 다른 규준이 될 것이다.

In accordance with his belief that philosophical problems arise from misunderstandings of the logic of our language, Wittgenstein's philosophical investigations were always focused on the problems of logic of language. Indeed, it can be said that his investigations were logical investigations. But what was the logic as conceived by him? He regarded logic as grammar from the beginning, but between his two different philosophical periods, there were important changes in his conceptions of grammar. In his earlier period, he understood the logic of language as the truth-functional syntax realizable in an ideal notation, while in his later period he regarded logic as the rules of language-use in various language games. It was a change from viewing logic as an ideally strict and universal system in which every logical possibilities are determined to viewing logic as an open system of non-strict grammatical rules specific to each language game. This paper deals with the gists of his earlier and later views on logic and the reasons for the change of his views, including specifically the reasons for the change of his views concerning the autonomy and necessity of logic as grammar.

The attribute grammar is a grammar for static semantic rules to overcome the difficulties of type checking. But this attribute grammar is difficult to write and understand by its additional rules. A grammar would be preferable if it has simple and small size of an attribute grammar. This paper shows how to decrease the size of an attribute grammar for an expression using LH method. This approach considers the types of an expression. That is, the construction of a semantic relation between the types of the expression can make it possible that an attribute grammar be written with its simpler and smaller size.

한국어나 일본어는 영어 등 서구의 언어와 비교하여 매우 발달된 경어 체계를 가지고 있다. 그러나 이러한 경어 체계는 이들 언어를 모국어로 사용하지 않는 사람들을 포함하여 모국어로 사용하는 많은 사람들까지도 정확하게 구사하기는 어려워 하는 것이 현실이다. 그럼에도 불구하고 경어 체계의 정확한 구사 능력은 적절한 어휘 선택 능력과 함께 자연스러운 의사 소통을 위한 중요한 언어 능력으로 간주되고 있다. 특히 기계번역기나 문법검사기를 구현하고자 할 때 이러한 경어 체계를 정확하게 이해하는 시스템의 구현은 한 차원 높은 자연스러운 표현을 제공하기 위하여 필수적이라고 할 수 있다. 본 논문에서는 한국어의 경어 체계를 조사하고 결합범주문법을 통하여 이를 검증하는 시스템을 소개한 뒤 사극 대본을 대상으로 하여 이 시스템의 성능을 확인한다.
