본 논문에서는 당 연구소 주관으로 연구개발정보센터(KORDIC), 서울대와 공동으로 개발중인 한영 기계번역 시스템, '에서로/KE'의 prototype system을 설명한다. 에서로/KE는 KORDIC에서 한국어 형태소 분석기와 Tagger를 개발하고, 서울대에서 한국어 구문해석기와 한영 변환기를 개발하고, SERI에서 영어 구문 생성기와 영어 형태소 생성기를 개발한다. 한국어 Tagger는 HMM에 기반하여 제작되었으며 sample 200문장에 대해 98.9%의 정확률을 보인다. 한국어 구문 해석기는 의존 문법에 기반하여 CYK 알고리즘을 사용하여 제작되었으며 중의성 해결을 위해 29개의 최적 parse 선택 규칙이 구현되어 있다. 한영 변환기는 collocation과 idiom에 기반하여 한영 변환을 수행한다. 영어 구문 생성기는 Tree 변환 언어인 GWL(Grammar Writing Language)를 사용하여 작성되었으며, 영어 형태소 생성기는 최종적으로 자연스러운 영어 표층문을 생성한다. 에서로/KE는 현재 1차년도 Prototype system이 Unix 환경에서 구현되어 있으며, 현재 각 모듈별 성능 개선과 대량 사전 구축을 통해 상용화될 예정이다.

As Internet and mobile technology is developing, the educational environment is changing from the traditional passive way into an active one driven by learners. It is important to construct the proper learner's profile for personalized education where learners are able to study according to their learning levels. The existing studies on ICT-based personalized education have mostly focused on vocabulary and learning contents. In this paper, learning profile is constructed with not only vocabulary but grammar to define a learner's learning status in more detailed way. A proficiency metric is defined which shows how a learner is accustomed to the learning contents. The simulational results present the suggested approach is effective to the evaluation essay data with each learner's proficiency that is determined after pre-learning process. Additionally, the proposed analysis technique enables to provide statistics or graphs of the learner's status and necessary data for the learner's learning contents.

This study suggests one of English teaching methods to improve English speaking proficiency for adult English learners. Contrary to the traditional English conversation teaching trends such as memorization of specific patterns or grammar-focused practices, the study introduces a storytelling based teaching of English speaking. To theoretically support the storytelling based English speaking teaching, the study investigates the possibility of the teaching method in three ways. First, the 12 speaking strategies focusing on contents of a story are introduced in the way of securing speech amounts as much as possible. Next, the five rhetoric components by Aristotle are introduced to relate to the storytelling teaching for the purpose of achieving the goal of speaking, which is to deliver what a speaker want to say more persuasively. Finally, through the investigation of the learner strategy uses, the possibility of storytelling English speaking teaching can be expected regardless of learners' low level of English proficiency.

This paper aims to explore the vocabulary difference between South and North Korean English textbooks as a first step toward a unified vocabulary list. To this end, both South and North Korean English textbooks in 2000s and 2010s are digitized into a corpus of text files, and a vocabulary list is constructed based on the corpus with reference to its concordances for the vocabulary use and contexts using AntConc 3.5.7. The vocabulary list of North Korean English textbooks are compared and found in their differences of quantity and quality of the English vocabulary in English education. Both quantitative and qualitative differences are found in between South and North Korean English textbook corpus. Both South and North aim that students learn about 3,000 words throughout the English education. North Korean English textbook contains more special academic vocabulary while South Korean English textbook is constrained by a strict vocabulary control which does not allow such a flexibility. Differences of vocabulary and their use are caused by the capitalistic market economy of South and the socialists' planned economy of North. Differences are also attributed to the religious words and grammatical vocabulary appearance.

The expression KES, one of the most commonly used words in the Korean language, has various usages. This expression is also used to express English-like cleft constructions. Korean seems to employ at least three different types of cleft constructions: predicational, identificational, and eventual. The paper tries to provide a constraint-based analysis of these three types of Korean cleft constructions and implement the analysis in the LKB(Linguistic Knowledge Building) system to check the feasibility of the analysis. In particular, the paper shows how a typed feature structure grammar, couched upon HPSG, can provide a robust basis for parsing Korean cleft constructions.

This Paper classified korean Parts-of-speech for korean-english machine translation and investigated morphological characters of each parts-of-speech. Korean standard grammar classified parts-of-speech by semantic, functional and formal character. Many rules make a difficulties the understanding of grammar structure and parts-of-speech classification and it is necessary to preprocess at machine translation. This paper classified korean parts-of-speech by one rule. The parts-of-speech suggested in this paper have a same syntactic role and same parts-of-speech with english dictionary, and express the structure of korean sentence. And also it can make target language by pattern matching in korean-english translation.

The purpose of this study is to suggest the effects of schema activation on reading comprehension. The subject of a sample survey was a 36 student experimental group and a 32 student control group, total 68 students at third grade class of C Middle School in Gwangju. Students ability to read English in the two groups were almost the same through, which was shown by pre-test administered before the beginning of the experiment. As a pre-reading activity, the experimental group was showed the pictures and vocabularies related to the text before reading. The other control group did Grammar Translation Method about text. The data needed for this study was obtained by the questionnaires with 25 questions about the English reading. The data analyzing method was t-test through the statistics program SPSS 12.0. The result of this study is as follows : First, the experimental group got a more meaningful score than the control group at the test. Second, pre-reading activities for providing prior knowledge of the text were affected by the student's English proficiency, peculiarly more effective on low level student than advanced level. Studying English reading through schema activation led the students to be present in classes with interests, so the experimental group showed more academic accomplishments than the control group.

This study focus on improving the text language proficiency regarding users' written text. In order to tone up accuracy improvement in writing, Computer Assisted Language Learning(CALL) can be primarily used as one of the most efficient tools. This study proposes a English Grammar Checking Application that can improve the accuracy over the current applications. The proposed system is capable of defining the difference between a Noun and a Noun Phrase which is critical in improving grammar accuracy for those who use Englilsh as a foreign language in English writing.

This research comes from the premise that a student-oriented English digital textbook's design should be age appropriate. Our study is intended for third-year elementary students, since that age is the onset of English education within the Korean national curriculum. Our proposal focuses on this age's need for concrete information. Three popular textbooks' designs were analyzed using Cress's "Grammar Flame of Visual Design [Cress 2006]," and the results reflected in our modified book design. Via two case studies, a focus group interview, questionnaire, and observation analysis, we learned that the design of an age-appropriate digital English textbook changes the effectiveness of the education. An age-appropriate modified digital English textbook improves student satisfaction and interest. Our research proposes a systematic textbook design guide for age-specific preferences and characteristics.

한국어의 띄어쓰기 현상은 단어별로 정형화된 띄어쓰기를 하는 영어나 띄어쓰기가 발달하지 않은 중국어, 일본어와는 다르게 독특한 형태로 발전되어 왔다. 기존에는 부분적인 띄어쓰기 오류를 바로잡아주는 형태의 연구가 많이 진행되었지만 이제는 문자인식이나 음성인식 등의 연구와 결합하여 띄어쓰기가 완전히 무시된 문장의 띄어쓰기를 자동으로 처리하는 방법에 대한 연구가 활발히 진행 중이다. 본 논문에서는 한국어의 띄어쓰기 현상과 띄어쓰기 복원 방법에 대한 기존의 연구에 대해서 살펴보고 기존의 방법으로는 저리하기 힘들었던 형태를 음절단위 결합범주문법으로 설명한다.
