'형태소 깎는 노인'은 국어사 자료를 처리하는 고성능 자동 형태분석기의 개발이 난항을 겪고 있는 상황에서 수동으로 형태분석 작업을 하는 연구자들을 지원하기 위하여 개발된 형태분석 보조기이다. 인간과 기계의 분업을 통해 인간의 피로를 최대한 줄이고, 단순 반복 형태에 대해서는 정답을 확실하게 제안할 수 있다는 것이 특징이다. 국어사 자료에는 한국어 정보처리를 위해 필요한 어휘 사전이 없으므로, 문법형태소 사전을 만들어 이를 단서로 조사/어미부와 어간부를 구분하도록 하였다. 이를 통해 구축된 소규모 형태분석 말뭉치들이 장기적으로는 자동 형태분석기의 성능 개선에 일조할 수 있을 것으로 기대한다.

최근 고객에게 개인화된 서비스를 제공하기 위한 방법의 하나인 CRM 시스템에 대한 연구가 활발히 이루어지고 있다. 본 논문에서는 룰 기반 CRM에서의 효율적인 룰 매칭을 목적으로 하는 시간요소를 고려한 룰 모델을 제안하고자 한다. 룰 매칭 시점관련조건을 고객관련조건과 구분함으로써 룰의 의미를 구조적으로 명백히 파악할 수 있고 룰 매칭 시에 룰 매칭 시점관련조건을 고객관련조건보다 먼저 수행할 수 있으므로 현재 시점에 룰 매칭을 해야 하는 룰들만을 대상으로 전체 고객 데이터를 검색할 수 있다. 이 때 룰 매칭 시간요소조건을 분류하기 위하여 필요한 카데고리 정보를 저장하고 계산 로직의 반복 수행을 막기 위한 목적으로 어휘를 정의하여 사용하는 방법에 대해서 설명한다.

The present study aims to investigate how teachers evaluate the Korean textbook they use for teaching primary students with multicultural background. Faced with the rich variety of materials available, it is often a challenging task for language teachers to select the most suitable coursebook. It is required that they carry out a detailed and comprehensive analysis of coursebooks and evaluate them with a set of criteria to guide the process. 32 Korean teachers took part in the primary KSL textbook evaluation that aimed to identify improvement areas. They used a pro-forma specified with 51 criteria. The teachers' responses to the questions in the pro-forma were statistically analyzed to draw implications for material evaluation. The findings of the analysis suggest that the KSL textbook for primary multicultural students need to be improved at the internal and external levels. Implications are discussed with focus on material evaluation and development, and KSL teacher professional development by helping them gain good and useful insights into the nature of the textbook, and sensitizing them to features to look for in teaching and learning materials.

The purpose of this study was to explore the characteristics of defining concrete and abstract nouns for the elderly. A total of 382 elderly participated in this study and they were classified into four age groups (i.e., over 55 to under 64, over 65 to under 74, over 75 to under 84, and over 85 year-old group). They performed the word definition task, composed of five concrete and five abstract nouns. The total scores and numbers and ratio of core/supplementary meanings were compared among four elderly groups. The frequency and ratio of error types were also examined. The results showed that all four groups had statistically significant differences in total scores, numbers and ratio of core and supplementary meaning of concrete noun definition task. In addition, abstract noun definition performances revealed group differences except the two groups (over 75 to under 84 and over 85-year-old group). The oldest group showed a sharp increase in error production. The highest ratio of error types were personal experience in over 55 to under 64-year-old group, and over 65 to under 74 year-old groups; and for the target word repetition in over 75 to under 84 year-old group; and no response in over 85 year-old group. In conclusion, both concrete and abstract word defining abilities had age-related deterioration. This decline results from impairment in spreading semantic knowledge within semantic network, which is vulnerable to aging. Characteristics of word definition for elderly can provide basic information to understand various neurolinguistic disorders associated with age.

In this paper, OUIG IDL CFE, provided by Sunsoft, is used to take a IDL definitions as inputs and parse those. OmniORB3 is introduced to support functionality of the ORB. Suns CFE produce AST after parsing inputs. Actually, the node of AST Is instances of classes which are derived from CFE classes. As the compiler back end visit the node of the AST using iterator class, UTL_ScopeActiveIterator, it dumps codes of output. During processing, two files are generated. Routines of generating code are invoked by BE_produce.cc and codes are produced while visiting root of AST, idl_global->root(). The dump* functions which dump codes is called according to the type of node. In this paper, Mapping C++ of IDL definition is experimented and results In the same as that of omniidl which is provided by omniORB3. The code of results behavior correctly on omniORB3. In the future, we are interested in optimizing the performance of marshalling code via IDL compiler.

The purposes of this study are to analyze sentence structures of word problems suggested in educational math programs for the 2nd grade elementary students and error patterns in sentence interpretation, and examine how sentence structures influence on errors during sentence comprehension. Based on the results of the analysis on 168 word problems suggested in math textbooks for the 2nd grade elementary students and error patterns observed while 160 the 2nd grade elementary students attempted to solve math word problems, easy and simple vocabularies are repeatedly used in the sentence structures of word problems and specific real life materials such as fruits, books, the number of people and etc. were repeatedly used. 51.56% of errors in sentence interpretation observed was higher than 39.20% of calculation errors and backtracking operation, a length of sentences, the numbers used in questions and off were analyzed to be involved in the errors in interpretation. Therefore, it is very important to make word problems from a student's points of view rather than a teacher's point of view and the study suggests that teachers help students learn basic sentence interpretation skills.

Current word sense disambiguation techniques employ various machine learning-based methods. Various approaches have been proposed to address this problem, including the knowledge base approach. This approach defines the sense of an ambiguous word in accordance with knowledge base information with no training corpus. In unsupervised learning techniques that use a knowledge base approach, graph-based and similarity-based methods have been the main research areas. The graph-based method has the advantage of constructing a semantic graph that delineates all paths between different senses that an ambiguous word may have. However, unnecessary semantic paths may be introduced, thereby increasing the risk of errors. To solve this problem and construct a fine-grained graph, in this paper, we propose a model that iteratively constructs the graph while eliminating unnecessary nodes and edges, i.e., senses and semantic paths. The hybrid similarity estimation model was applied to estimate a more accurate sense in the constructed semantic graph. Because the proposed model uses BabelNet, a multilingual lexical knowledge base, the model is not limited to a specific language.

한국어 문장을 구조 분석할 때에 모호성을 발생시키는 유형 중의 하나가 나열 및 병렬형이다. 문장 구조 복잡도를 증가시키는 나열 및 병렬형을 구조 분석 전에 미리 하나의 단위로 묶어서 처리하는 것이 문장 구조 분석의 정확도를 높이는데 중요하다. 본 연구에서는 형태소 태그를 이용한 기본 규칙으로 문장을 청크 단위로 분할하고 분할된 청크 중에서 나열형을 인식하여 해당되는 청크들을 하나의 나열 청크로 통합하여 청크의 개수를 줄인다. 병렬형에 대해서는 반복되는 병렬 청크의 범위와 생략된 용언을 복원한다. 이러한 인식은 첫 단계로 기호(symbol)를 중심으로 구축된 간단한 규칙으로 인식을 하고 이러한 규칙에 해당되지 않는 형태의 나열 및 병렬형은 Maximum Entropy 모델을 이용하여 적용한다. ME모델은 어휘자질, 형태소 품사 자질, 거리 자질, 의미자질, 구 단위 태그 자질(NP:명사구, VP:동사구, AP:형용사구), BIO 태그(Begin, Inside, Outside) 자질에 대한 ME(Maximum Entropy) 모델을 이용하여 구축되었다.
