사용자 맞춤 서비스를 위하여 온라인상에서 사용자의 관심 분야를 파악하고자 하는 경우에는 적은 수의 훈련 예제로 효율적인 학습이 가능한 능동적 학습이 적절하다. 능동적 학습을 효과적으로 적용하기 위하여 사용자에게 문의할 가치가 높은 예제를 선정하는 것도 중요하지만, 사용자 편의를 위해서는 문의 횟수를 가능한 최소화하여야 한다. 문의 횟수를 줄이면서도 많은 수의 훈련 예제를 획득하기 위해서는 복수의 문의 예제들을 사용자에게 한꺼번에 제시하고 그 관심 여부를 표한하게 하는 것이 효과적이다. 본 논문에서는 능동적 학습 적용 시 사용자에게 문의할 가치가 높은 복수 문의 예제들을 효과적으로 선정하기 위하여 가중치 반영 군집화를 적용하는 방안을 제안한다. 본 제안 방안은 먼저 각 예제의 문의 예제로서의 가치를 파악하고 이를 가중치로 삼아 군집화를 수행하여 상대적으로 유사한 예제들의 집합을 구성한다. 이어서 생성된 각각의 군집에서 가장 보편적인 예제를 문의 예제로 선정하면 선정된 각각의 문의 예지는 문의할 가치가 높으면서 함께 문의하게 될 예제들은 서로 충분히 달라 학습에 보다 유용하게 사용할 수 있는 훈련 예제들을 얻을 수 있다. 문서 분류 문제를 대상으로 본 제안 방안을 실험한 결과, 단순히 문의 가치가 높은 복수의 예제들을 함께 문의할 예제들로 선정하는 방안에 비해 학습 성능이 뛰어났으며, 한 번에 문의하는 예제 수를 증가시키더라도 분류기의 성능 저하가 적음을 확인하였다.

이 논문은 일상적인 직설 조건문에 대한 새로운 이해를 제시함으로써 반 맥기가 전건 긍정법에 대한 반례라고 주장하는 예들에 대한 체계적인 이해방식을 제시하고 이것들이 전건 긍정법의 반례가 아니라는 것을 보인다. 직설 조건문에 대한 새로운 이해란 그것이 전건인 경우 후건의 조건적 확률이 높다는 것을 주장하는 문장이며 따라서 이 조건적 확률이 높은 경우 참이 되는 문장으로 봄으로써 직설 조건문이 그 논리적 형식에 있어서 조건문이 아니라는 것이다. 또한, 이렇게 이해되었을 때 반 맥기가 염두에 두고 있던 직설 조건문의 세 가지 특징이 역시 설명될 수 있다는 것을 보임으로써, 이 새로운 이해방식이 타당함을 보인다.

이벤트 추출은 텍스트에서 구조화된 이벤트를 분석하는 것이다. 본 논문은 대화문에서 발생하는 다양한 종류의 이벤트를 다루기 위해 이벤트 스키마를 프레임넷으로 정한다. 대화문에서의 이벤트 논항은 이벤트가 발생하는 문장 뿐만 아니라 다른 문장 또는 대화에 참여하는 발화자에서 발생할 수 있다. 대화문 주석 데이터의 부재로 대화문에서의 프레임 파싱 연구는 진행되지 않았다. 본 논문이 제안하는 모델은 대화문에서의 이벤트 논항 구간이 주어졌을 때, 논항 구간의 역할을 식별하는 모델이다. 해당 모델은 이벤트를 유발한 어휘, 논항 구간, 논항 역할 간의 관계를 학습한다. 대화문 주석 데이터의 부족을 극복하기 위해 문어체 주석 데이터인 한국어 프레임넷을 활용하여 전이학습을 진행한다. 이를 통해 정확도 51.21%를 달성한다.

Zero anaphora occurs frequently in Korean complex sentences, and it makes the interpretation of sentences difficult. This paper proposes splitting algorithms and zero anaphora recovery rules for the purpose of handling zero anaphora, and also presents a resolution methodology. The paper covers quotations, conjunctive sentences and embedded sentences out of the complex sentences shown in the newspaper articles, with an exclusion of embedded sentences of auxiliary verb. We manage the quotations using the equivalent noun phrase deletion rule according to subject person constraint, the nominalized embedded sentences using the equivalent noun phrase deletion rule, the adnominal embedded sentences using the relative noun phrase deletion rule and the conjunctive sentences using the conjunction reduction rule in reverse. The classified table of the endings which relate to a formation of the complex sentences is used for splitting the complex sentences, and the syntactic rules, applied when being omitted, are used in reverse for recovering zero anaphora. The presented rule showed the result of 83.53% in perfect resolution and 11.52% in partial resolution.

The Gwanghwamun Gate of the Gyeongbokgung Palace was established in 1866 when Heungseon Daewongun rebuilt the Gyeongbokgung Palace. In Gwanghwamun, a large platform, woldae was established to reveal its hierarchy. The Gwanghwamun Woldae was equipped with stone railings on the left and right sides, fishing routes in the center, and stairs and slopes to the south. The Yongdu Stone was installed on the south side of the slope, which connected to the woldae, to express the path of the king in a formative manner. The Woldae King Road in Gwanghwamun was expanded in 1915 as the Joseon Promotion Conference was held at the Gyeongbokgung Palace and the woldae was destroyed around 1925. Since then, the figure has not been found since the time before the Gwanghwamun Gate. In the Donggureung royal tombs, there are many stones that are not placed in the royal tombs, including voussoir arch stones, Munsojeon Gugi-bi, as well as Nangan-Seokju, Dongja-seok, and Juk-seok, which are elements of the stone railings. These stone railings and Yongdu-seok are seen as stone objects of the Gwanghwamun Woldae, which can be found through the analysis of the style of the times and comparison with modern photographs.

This paper examines the petition to the king of Doam(陶菴) Leejae(李縡), one of the key figures of 18th century. He wrote a total of 49 he petition to the king, mostly resignation petition to the king. He emphasized the genuine feelings and emphasized the accurate persuasion logic when he was writing a petition to the king. It is not contradictory to these elements, looking at his actual situation he wrote. He wrote the resignation petition to the king three times to resign Daejehak (大提學), he changed his persuasion logic in each of the resignation petition to the king. We can look at the aspect of transforming persuasion logic on the same topic. His resignation petition to the king, for the first time, was particularly well structured in terms of composition, and used a proper accent method. His resignation petition to the king has the beautiful literary art of gomun(古文), such as the expression of the so-called munjongjasoon(文從字順) and the composition of paragraph organically corresponding. The best work of his resignation petition to the king is Maneonso(萬言疏). The contents criticized Yeongjo(英祖)'s tangpyeongchaek(蕩平策) while evaluating Sinimoksa(辛壬獄事). It consists of a total of 5,300 letters. This work repeatedly used the irony, the method of seolui(設疑), and the incremental method to criticize the tangpyeongchaek(蕩平策), and put Yeongjo(英祖)'s position to the corner. This work is an example of other the resignation petition to the king.

Identifying citing sentences from article full-text is a prerequisite for creating a variety of future academic information services such as citation-based automatic summarization, automatic generation of review articles, sentiment analysis of citing statements, information retrieval based on citation contexts, etc. However, finding citing sentences is not easy due to the existence of implicit citing sentences which do not have explicit citation markers. While several methods have been proposed to attack this problem for English, it is difficult to find such automatic methods for Korean academic literature. This article presents a rule-based approach to identifying Korean citing sentences. Experiments show that the proposed method could find 30% of implicit citing sentences in our test data in nearly 70% precision.

Door is an important object to understand given environment and it could be used to distinguish with corridors and rooms. Doors are widely used natural landmark in mobile robotics for localization and navigation. However, almost algorithm for door recognition with camera is difficult real-time application because feature extraction and matching have heavy computation complexity. This paper proposes a method to recognize a door in corridor. First, we extract distinguished lines which have high possibility to comprise of door using Hough transformation. Then, we detect candidate of door region by applying previously extracted lines to first-stage visual fuzzy system. Finally, door regions are determined by verifying knob region in candidate of door region suing second-stage visual fuzzy system.

This study was carried out to evaluate the feasibility of using HDF as surface panels as well as core materials for flush door manufacturing. Six core constructions were developed and applied to manufacture door specimens and conventional skin door specimen was also manufactured for comparison. Door specimens were tested under changing interior environmental condition for 3~4 months during winter and summer seasons. During the test period, deformation of doors were measured weekly, and temperature and relative humidity of testing area were also recorded. From this study, it was concluded that HDF can be used to manufacture quality flush doors and core construction developed in this study showed good quality compared to conventional skin door. Deformation of doors increased as temperature and relative humidity of the surrounding environment increased. Flush doors generally showed less deformation than skin doors, and evaluated to be stable and good quality when compared to skin door.
