This study investigates the semantic and prosodic properties of the so-called contrastive topic. We posit two informational primitives, namely, topical feature [+-T] and focal feature [+-F], from which four different informational categories, i.e., [+T, +F], [+T, -F], [-T, +F], and [-T, -F], are yielded. It is proposed that the informational category of contrastive topic has focal property [+F] as well as topical property [+T]. Based on the semantic approach that regards the function of [+F] as identificational predication and that of [+T] as forming a semantic conditional clause, it is shown that the semantic function of contrastive topic, which is specified as [+T, +F], is the combination of these two functions, i.e., identificational predication in a semantic conditional clause. This is supported by a scrutinized exploration of the prosodic pattern of English contrastive topic.

This study aims to extract key topics through text mining of incident records (incident history, post-incident measures, preventive measures) from construction safety accident case data available on the public data portal. It also seeks to provide fundamental insights contributing to the establishment of manuals for disaster prevention by identifying correlations between these topics. After pre-processing the input data, we used the LDA-based topic modeling technique to derive the main topics. Consequently, we obtained five topics related to incident history, and four topics each related to post-incident measures and preventive measures. Although no dominant patterns emerged from the topic pattern analysis, the study holds significance as it provides quantitative information on the follow-up actions related to the incident history, thereby suggesting practical implications for the establishment of a preventive decision-making system through the linkage between accident history and subsequent measures for reccurrence prevention.

This study aims to analyze research trends regarding outdoor wear. For this purpose, the data-collection period was limited to January 2002-October 2022, and the collection consisted of titles of papers, academic names, abstracts, and publication years from the Research Information Sharing Service (RISS). Frequency analysis was conducted on 227 papers in total to check academic journals and annual trends, and LDA topic-modeling analysis was conducted using 20,964 tokens. Data pre-processing was performed prior to topic-modeling analysis; after that, topic-modeling analysis, core topic derivation, and visualization were performed using a Python algorithm. A total of eight topics were obtained from the comprehensive analysis: experiential marketing and lifestyle, property and evaluation of outdoor wear, design and patterns of outdoor wear, outdoor-wear purchase behavior, color, designs and materials of outdoor wear, promotional strategies for outdoor wear, purchase intention and satisfaction depending on the brand image of outdoor wear, differences in outdoor wear preferences by consumer group. The results of topic-modeling analysis revealed that the topic, which includes a study on the design and material of outdoor wear and the pattern of jackets related to the overall shape, was the highest at 30.9% of the total topics. The next highest topic was also the design and color of outdoor wear, indicating that design-related research was the main research topic in outdoor wear research. It is hoped that analyzing outdoor wear research will help comprehend the research conducted thus far and reveal future directions.

Most approaches to human action recognition is limited due to the use of simple action datasets under controlled environments or focus on excessively localized features without sufficiently exploring the spatio-temporal information. This paper proposed a framework for recognizing realistic human actions. Specifically, a new action representation is proposed based on computing a rich set of descriptors from keypoint trajectories. To obtain efficient and compact representations for actions, we develop a feature fusion method to combine spatial-temporal local motion descriptors by the movement of the camera which is detected by the distribution of spatio-temporal interest points in the clips. A new topic model called Markov Semantic Model is proposed for semantic feature selection which relies on the different kinds of dependencies between words produced by "syntactic " and "semantic" constraints. The informative features are selected collaboratively based on the different types of dependencies between words produced by short range and long range constraints. Building on the nonlinear SVMs, we validate this proposed hierarchical framework on several realistic action datasets.

이 연구는 2019년 판문점 남북미 정상 회동 트윗을 타임 시퀀스와 함께 수집하여 시퀀셜 토픽모델링인 DTM으로 분석하였다. 트위터와 같은 마이크로 블로깅 서비스는 단일 이벤트에 뉴스와 오피니언이 혼재된 비정형 데이터가 대규모로 동시에 발생하고, 정보와 반응이 동일 메시지 형식으로 생산된다. 때문에 토픽 트렌드를 파악하려면 시퀀셜 데이터의 특성을 반영하여 패턴 분석을 해야 맥락적 의미를 알 수 있다. 토픽 일관성 점수를 구해 LDA를 평가한 후 DTM을 계산한 결과, 뉴스 보도와 오피니언 관련 토픽 30개가 도출되었고, 각 토픽과 키워드는 시간에 따라 발생 확률이 역동적으로 진화하고 있었다. 결론적으로 DTM은 특정 이벤트에 대한 사회 전반에 나타난 통합적 토픽 추이를 시간에 따라 분석하는데 적합한 모델임을 밝혔다.

The subject of the simultaneous measuring system of base pattern and deposition pattern is a new research topic on a defect inspection of OLED. In this paper, we propose a new OLED inspection method that simultaneously measures standard and deposition pattern images. This method reduces unnecessary processes and tac time during OLED inspection. For an additional reduction of the tac time during pattern measurement, the ROI was configured to measure only in the designated ROI area instead of measuring the entire area of an image. During the ROI set-up, the value of effective deposition pattern area is included so that if the deposition pattern is out of the ROI zone, it would be treated as a defect before measuring the size and center point of the pattern. As a result, the tac time and inspection process could be shortened. The proposed method also could be applied to the OLED manufacturing process. Production of OLED could be increased by reducing tac time and inspection process.

과학적 지식을 얻는 과정은 연구자의 연구를 통해 이루어진다. 연구자들은 과학의 불확실성을 다루고 과학적 지식의 확실성을 구축해나간다. 즉, 과학적 지식을 얻기 위해서 불확실성은 반드시 거쳐가야 하는 필수적인 단계로 인식되고 있다. 현존하는 불확실성의 특성을 파악하는 연구는 언어학적 접근의 hedging 연구를 통해 소개되었으며 컴퓨터 언어학에서 수작업 기반으로 불확실성 단어 코퍼스를 구축해왔다. 기존의 연구들은 불확실성 단어의 단순 출현 빈도를 기반으로 특정 학문 영역의 불확실성의 특성을 파악해오는데 그쳤다. 따라서 본 연구에서는 문장 내 생의학적 주장이 중요한 역할을 하는 생의학 문헌을 대상으로 불확실성 단어 기반 과학적 지식의 패턴을 시간의 흐름에 따라 살펴보고자 한다. 이를 위해 생의학 온톨로지인 UMLS에서 제공하는 의미적 술어를 기반으로 생의학 명제를 분석하였으며, 학문 분야의 패턴을 파악하는데 용이한 DMR 토픽 모델링을 적용하여 생의학 개체의 불확실성 기반 토픽의 동향을 종합적으로 파악하였다. 시간이 흐름에 따라 과학적 지식의 표현은 불확실성이 감소하는 패턴으로 연구의 발전이 이루어지고 있음을 확인하였다.

복잡한 의미관계를 정의하는 온톨로지를 구축하는 일은 매우 정밀하고 전문적인 작업이다. 잘 구축된 온톨로지를 응용 시스템에 활용하기 위해서는 온톨로지 클래스에 대한 많은 인스턴스 정보를 구축해야 한다. 본 논문은 온톨로지 인스턴스 정보 추출을 위하여 방대한 양의 웹 문서로부터 주어진 주제에 적합한 문서만을 추출하는 주제 중심 웹 문서 수집 알고리즘을 제안하고, 이 알고리즘을 바탕으로 문서 수집 시스템을 개발한다. 제안하는 문서 수집 알고리즘은 URL의 패턴을 이용하여 주제에 적합한 링크만을 추출함으로써 빠른 속도의 문서 수집을 가능하게 한다. 또한 링크 블록 텍스트에 대한 퍼지집합으로 표현된 주제 적합도는 문서의 주제 관련성을 지능적으로 판단하여 주제 중심 문서 수집의 정확도를 향상시킨다.
