지식iN 등의 지식검색 서비스는 잘못된 답변으로 인한 낮은 신뢰성과 다수의 중복 답변 등의 문제점을 가진다. 질의문 '세상에서 가장 큰 나라'에 대해서 관련된 모든 질문과 답변을 제시하지 않고 질의문과 관련된 다수의 답변을 분석하여 답변 '러시아'를 추천하여 제시할 수 있다면 지식검색의 효용성과 신뢰성이 크게 향상될 수 있다. 본 논문에서는 질문-답변의 유형을 단어, 글, 도표, 목록의 네가지로 분류하고, 그 중 단어 유형에 대한 답변 추천 방법을 제시한다. 질의문에 대해 검색된 질문을 군집화하고, 질문에 대한 답변들에 대해서 TF, IDF, 어휘간 거리 정보를 다양하게 결합하여 어휘의 점수를 계산한다. 각 군집에서 가장 높은 점수를 가지는 어휘를 해당 군집에서 가장 중요한 어휘로 보고 추천 정답으로 제시한다. 단어 유형인 질문 100개에 대한 네이버 지식iN에 대한 시스템 평가에서 추천된 상위 1위에 대해서는 68%의 정답률을, 상위 5위까지에 대해서는 89%의 정답률을 보였다.

This experimental study proposes a multi-document summarization method that produces optimal summaries in which users can find answers to their queries. In order to identify the most effective method for this purpose, the performance of the three summarization methods were compared. The investigated methods are sentence clustering, passage extraction through spreading activation, and clustering-passage extraction hybrid methods. The effectiveness of each summarizing method was evaluated by two criteria used to measure the accuracy and the redundancy of a summary. The passage extraction method using the sequential bnb search algorithm proved to be most effective in summarizing multiple documents with regard to summarization precision. This study proposes the passage extraction method as the optimal multi-document summarization method.

Automatic swing door for an automotive application is considered. The equation of motion for a driver side swing door is introduced and gravity cancellation control scheme is adapted. The control scheme supposed to cancel the moment due to the tilt of the car. A speed control is suggested for door operation automation but the output of the speed control is not suppose to be precise as for the manufacturing system control. In the frame of the velocity control of the door, feedback linearization was applied for collision detection. The collision detection performance is satisfactory. The estimate of the magnitude of disturbance due to the collision is close to the actual magnitude of disturbance. Simulation study has been performed to gain insight into the system behavior. Also real test on the prototype hardware has been performed for verification purpose.

Recently, door locks have become popular. However, it is often more difficult to recognize the vulnerability of the door lock than to recognize it as more convenient and secure than a mechanical key. Therefore, in this study, the function of the door lock was improved and the weak points were reinforced. Door lock is vulnerable to heat when a fire occurs, so that the door may not open. Therefore, the door is automatically opened when the internal temperature of the fire site exceeds a predetermined temperature by attaching a heat sensor. In the room, the door was automatically opened without having to press the password. Through the proposed function, it can be expected to prevent the casualties in case of fire.

In this paper, we deal with implementation issues of an unknown word classifier for middle-school level English writing test. We define the type of unknown words occurred in English text and discuss the detection process for unknown words. Also, we define the type of swear words occurred in students's English writings, and suggest how to handle this type of words. We implement an unknown word classifier with a swear detection module for developing an automatic English writing scoring system. By experiments with actual test data, we evaluate the accuracy of the unknown word classifier as well as the swear detection module.

본 논문에서는 기호로 둘러싸인 내포문이 포함된 문장의 번역 성능을 높이는 방법을 제안한다. 입력 문장에서 내포문을 추출하여 여러 문장으로 나타내고, 각각의 문장들을 번역한다. 그리고 번역된 문장들을 복원정보를 활용하여 최종 번역 문장을 생성한다. 이러한 방법론은 입력 문장의 길이를 줄여주며, 그로 인하여 문장 구조가 단순해져 번역 품질이 향상된다. 본 논문에서는 한국어-베트남어 통계 기반 번역기에 대하여 제안한 방법론을 적용하고 실험하였다. 그 결과 BLEU 점수가 약 1.5 향상된 것을 확인할 수 있었다.

본 연구의 목적은 문-스펜서 색채조화영역별로 피부색과 복장색의 배색이미지를 분석하여 피부색을 기준으로 한 복장색의 의복이미지를 파악하는 것이다. 연구결과 첫째, 피부색과 복장색의 배색은 3가지 차원의 인상으로 구성되었다(평가, 활동, 조화). 둘째, 문-스펜서의 색채조화론을 적용하여 시각적 평가의 차이를 분석한 결과 조화영역들은 비슷하게 지각됨을 알 수 있었다. 부조화영역간에는 평가차원과 활동차원이 달리 지각됨을 알 수 있다. 셋째, 샛체조화론의 적용으로 분류되는 조화영역별 배색이미지를 분석한 결과, 동일색상들의 배색은 대체로 미도가 높은 편이었다. 제2부조화색상들의 배색은 미도가 낮았다. 유사색상중 빨강색 계열의 배색은 미도가 높았으며 노랑색 계역의 배색은 미도가 낮았다. 제2부조화색 계열, 청녹색 계열의 배색은 미도가 높은 편이며 남색 계열, 보라색 계열의 배색은 대체로 미도가 높았다. 무채색 계열의 배색은 세련된, 아름다운, 사고싶은, 보기좋은, 마음에 드는, 조화된, 멋있는 피부색과 어울리는, 매력있는, 인물이 돋보이는 이미지를 가지고 있다.

This paper describes the hybrid document summarization using the indicative summarization and the query-based summarization. The learning models are built from teaming documents in order to extract topic phrases. We use Naive Bayesian, Decision Tree and Supported Vector Machine as the machine learning algorithm. The system extracts topic phrases automatically from new document based on these models and outputs the summary of the document using query-based summarization which considers the extracted topic phrases as queries and calculates the locality-based similarity of each topic phrase. We examine how the topic phrases affect the summarization and how many phrases are proper to summarization. Then, we evaluate the extracted summary by comparing with manual summary, and we also compare our summarization system with summarization mettled from MS-Word.

Future science fiction science film science fiction film can easily see the appearance of the futuristic inquiry. Even if a person does not open the door by force, the door is opened and closed by the system. Even now, such a door can be found easily. However, in the past, people who have not been able to perceive people have been used only in public places such as department stores and marts, where there are many people who are inundated. However, a lot of researches are being done now, and we are pursuing convenience in everyday life by integrating the image processing technology that has been developed and developed many times, by implementing the automatic door which is not infringed by the personal life and is impossible for anyone to access.

The present study was based on the specimens collected from the Yellow Sea between Sept. 17 and Oct. 2, 1992 within the framework of Korea-China Yellow Sea Research Joint Program. Additional materials were also provided from the benthic samples collected from the tidal mud flats surrounding Inchon, Korea and from the subtidal shallow waters of the Kwang-yang Bay in the southern coast of Korea. Paraonid polychaetes have not been previously reported form Korea waters. Here, a total of six species in two genera are described and illustrated, and they are newly recorded in Korea polychaetous fauna : Cirrophorus furcatus, Cirrophorus armatus, Cirrophorus branchiatus, Aricidea (Aedicira) pacifica, Aricidea (Aricidea) wassi, adn Aficidea (Acesta) assimilis.
