Relation extraction plays a role in for the process of transforming a sentence into a form of knowledge base. In this paper, we focus on predicates in a sentence and aim to identify the relevant knowledge base properties required to elucidate the relationship between entities, which enables a computer to understand the meaning of a sentence more clearly. Distant Supervision is a well-known approach for relation extraction, and it performs lexicalization tasks for knowledge base properties by generating a large amount of labeled data automatically. In other words, the predicate in a sentence will be linked or mapped to the possible properties which are defined by some ontologies in the knowledge base. This lexical and ontological linking of information provides us with a way of generating structured information and a basis for enrichment of the knowledge base.

Accessible negative results are relevant for researchers and clinicians not only to limit their search space but also to prevent the costly re-exploration of research hypotheses. However, most biomedical relation extraction datasets do not seek to distinguish between a false and a negative relation among two biomedical entities. Furthermore, datasets created using distant supervision techniques also have some false negative relations that constitute undocumented/ unknown relations (missing from a knowledge base). We propose to improve the distinction between these concepts, by revising a subset of the relations marked as false on the phenotype-gene relations corpus and give the first steps to automatically distinguish between the false (F), negative (N), and unknown (U) results. Our work resulted in a sample of 127 manually annotated FNU relations and a weighted-F1 of 0.5609 for their automatic distinction. This work was developed during the 6th Biomedical Linked Annotation Hackathon (BLAH6).

관계 추출을 위한 원격 지도 학습은 사람의 개입 없이 대규모 데이터를 생성할 수 있는 효율적인 방법이다. 그러나 원격 지도 학습은 노이즈 데이터 문제가 있으며, 노이즈 데이터는 두 가지 유형으로 나눌 수 있다. 첫 번째는 관계 표현 자체가 없는 문장이 연결된 경우이고, 두 번째는 관계 표현은 있는 문장이지만 다른 관계 표현도 함께 가지는 경우이다. 주로 문장의 길이가 길고 복잡한 문장에서 두 번째 노이즈 데이터 유형이 자주 발견된다. 본 연구는 두 번째 경우의 노이즈를 줄임으로써 관계 추출 모델의 성능을 향상시키기 위해 확장된 최단 의존 경로를 사용하는 CNN 기반 관계 추출 모델을 제안한다. 본 논문에서 제안한 방법의 우수성을 입증하기 위해, 한국어 위키피디아와 DBpedia 기반의 원격 지도 학습 데이터를 수집하여 평가한 결과, 본 논문에서 제안한 방법이 위 문제를 해결하는데 효과적이라는 것을 확인하였다.

기계적 학습을 위해서는 일반적으로 많은 양의 수동 주석데이터(Manually Labeled Data)가 요구된다. 원격지도(Distant Supervision)는 현실적으로 부족한 주석데이터(Labeled Data)를 대신해 자동적으로 주석데이터를 수집하여 학습하는 접근 방식으로 관계 추출(Relation Extracion) 문제에 널리 활용되고 있다. 이때 필연적으로 많은 노이즈(Noise)가 발생되는데, 적합성 검증(Relevance Verification)을 통해 수집된 학습데이터를 정제함으로써 노이즈로 인한 변동성을 줄이고 결과적으로 향상된 성능을 보여주는 관계 추출 방법을 제시한다.

Health policy is directed to equity in the provision of primary care for rural people before the year of 2, 000. This study aimed to define and identify the need for physician's care by using empirical data, and suggested an alternative of the primary care delivery system in rural areas to the government. 1. Twenty percent of the study population wanted to obtain any form of medical care services. : 9.3 percent of the population was in need for physician's care; 15 percent of the need was met by physicians, while 85 percent remained unmet at the time of survey in 1979. 2. For meeting all the need for physician's primary care, 2.9 annual physician visits per capita are demanded. An alternative, which was devised in some favourable way at reasonable cost in rural settings, was suggested. It was to deploy the physician extender such as community health practitioner in the infrastructure of the health care delivery system, whose supervision is provided by physician, based on experience of the KHDI health demonstration project. 3. One physician, two community health practitioners and two community health aides should be assigned in distant locations for meeting all the estimated need for physician's primary care for 10, 000 rural underserved residents.

In accordance with the establishment of 200 nautical miles EEZ regime as a customary international law since the mid - 1980s, the area of global high seas became reduced relatively. On the other hand, the importance of high seas fishing ground became serious for the distant-water fishing states like Korea. But it can be expected that international dispute on the jurisdictional problem of the fishing vessels engaging high sea fishery will occur frequently owing to institutional inertia of the UNLOS Convention on this matter. "The Draft Agreement to Promote Compliance with International Conservation and Management Measures by Fishing Vessels on the High Seas" as an international code of conduct for responsible fishing which was adopted by FAO in 1993 is providing the more consolidating and definiting rules for jurisdictional responsibility of flag states to make completion the loophole of the UNLOS Convention. As a precondition for the effective control and enforcement of activities of the fishing vessels engaging high sea fishery, the Draft Agreement is providing some articles allowing the flag states to hold the rights of granting nationality, fishery permission, fishery supervision and control with punishment for the fishing vessels entitled to fly their own flag. Accordingly it can be evaluated that this Draft Agreement does not deviate on the whole from the traditional practice and the basic legal principle of the UNLOS Convention.

The overall study of Samsaebulhoedo (painting of the Assembly of Buddhas of Three Ages) at Yongjusa Temple has focused on dating it, analyzing the painting style, identifying its painter, and scrutinizing the related documents. However, its greater coherence could be achieved through additional support from empirical evidence and logical consistency. Recent studies on Samsaebulhoedo at Yongjusa Temple that postulate that the painting could have been produced by a monk-painter in the late nineteenth century and that an original version produced in 1790 could have been retouched by a painter in the 1920s using a Western painting style lack such empirical proof and logic. Although King Jeongjo's son was not yet installed as crown prince, the Samsaebulhoedo at Yongjusa Temple contained a conventional written prayer wishing for a long life for the king, queen, and crown prince: "May his majesty the King live long / May her majesty the Queen live long / May his highness the Crown Prince live long" (主上殿下壽萬歲, 王妃殿下壽萬歲, 世子邸下壽萬歲). Later, this phrase was erased using cinnabar and revised to include unusual content in an exceptional order: "May his majesty the King live long / May his highness the King's Affectionate Mother (Jagung) live long / May her majesty the Queen live long / May his highness the Crown Prince live long" (主上殿下壽萬歲, 慈宮邸下壽萬歲, 王妃殿下壽萬歲, 世子邸下壽萬歲). A comprehensive comparison of the formats and contents in written prayers found on late Joseon Buddhist paintings and a careful analysis of royal liturgy during the reign of King Jeongjo reveal Samsaebulhoedo at Yongjusa Temple to be an original version produced at the time of the founding of Yongjusa Temple in 1790. According to a comparative analysis of formats, iconography, styles, aesthetic sensibilities, and techniques found in Buddhist paintings and paintings by Joseon court painters from the eighteenth and nineteenth centuries, Samsaebulhoedo at Yongjusa Temple bears features characteristic of paintings produced around 1790, which corresponds to the result of analysis on the written prayer. Buddhist paintings created up to the early eighteenth century show deities with their sizes determined by their religious status and a two-dimensional conceptual composition based on the traditional perspective of depicting close objects in the lower section and distant objects above. This Samsaebulhoedo, however, systematically places the Buddhist deities within a threedimensional space constructed by applying a linear perspective. Through the extensive employment of chiaroscuro as found in Western painting, it expresses white highlights and shadows, evoking a feeling that the magnificent world of the Buddhas of the Three Ages actually unfolds in front of viewers. Since the inner order of a linear perspective and the outer illusion of chiaroscuro shading are intimately related to each other, it is difficult to believe that the white highlights were a later addition. Moreover, the creative convergence of highly-developed Western painting style and techniques that is on display in this Samsaebulhoedo could only have been achieved by late-Joseon court painters working during the reign of King Jeongjo, including Kim Hongdo, Yi Myeong-gi, and Kim Deuksin. Deungun, the head monk of Yongjusa Temple, wrote Yongjusa sajeok (History of Yongjusa Temple) by compiling the historical records on the temple that had been transmitted since its founding. In Yongjusa sajeok, Deungun recorded that Kim Hongdo painted Samsaebulhoedo as if it were a historical fact. The Joseon royal court's official records, Ilseongnok (Daily Records of the Royal Court and Important Officials) and Suwonbu jiryeong deungnok (Suwon Construction Records), indicate that Kim Hongdo, Yi Myeong-gi, and Kim Deuksin all served as a supervisor (gamdong) for the production of Buddhist paintings. Since within Joseon's hierarchical administrative system it was considered improper to allow court painters of government position to create Buddhist paintings which had previously been produced by monk-painters, they were appointed as gamdong in name only to avoid a political liability. In reality, court painters were ordered to create Buddhist paintings. During their reigns, King Yeongjo and King Jeongjo summoned the literati painters Jo Yeongseok and Kang Sehwang to serve as gamdong for the production of royal portraits and requested that they paint these portraits as well. Thus, the boundary between the concept of supervision and that of painting occasionally blurred. Supervision did not completely preclude painting, and a gamdong could also serve as a painter. In this light, the historical records in Yongjusa sajeok are not inconsistent with those in Ilseongnok, Suwonbu jiryeong deungnok, and a prayer written by Hwang Deok-sun, which was found inside the canopy in Daeungjeon Hall at Yongjusa Temple. These records provided the same content in different forms as required for their purposes and according to the context. This approach to the Samsaebulhoedo at Yongjusa Temple will lead to a more coherent explanation of dating the painting, analyzing its style, identifying its painter, and interpreting the relevant documents based on empirical grounds and logical consistency.
