CLEval: Character-Level Evaluation for Text Detection and Recognition Tasks

Abstract: Despite the recent success of text detection and recognition methods, existing evaluation metrics fail to provide a fair and reliable comparison among those methods. In addition, there exists no end-to-end evaluation metric that takes characteristics of OCR tasks into account. Previous end-to-end metric contains cascaded errors from the binary scoring process applied in both detection and recognition tasks. Ignoring partially correct results raises a gap between quantitative and qualitative analysis, and prevents fine-grained assessment. Based on the fact that character is a key element of text, we hereby propose a Character-Level Evaluation metric (CLEval). In CLEval, the \textit{instance matching} process handles split and merge detection cases, and the \textit{scoring process} conducts character-level evaluation. By aggregating character-level scores, the CLEval metric provides a fine-grained evaluation of end-to-end results composed of the detection and recognition as well as individual evaluations for each module from the end-performance perspective. We believe that our metrics can play a key role in developing and analyzing state-of-the-art text detection and recognition methods. The evaluation code is publicly available at this https URL.

Relationship between Service Design Tools and Service Innovation - Focused on Korean Healthcare Cases

Abstract: In this paper, we have determined the strategic service design tools and methods by examining the associations among different size of health and medical service industry and investigate if service design tools and methods are positively related to service innovation. The categorized service design tools and methods in the service design will be used to examine the associations among two different types of health and medical service providers which are classified according to the operational regulations and sizes in Korea: clinics and general hospitals as a case study. Findings support that health and medical service industry may improve their performance winning the challenges associated with using the most appropriate strategic service design tools and methods in the service design.

The Relationship Between Psychological Health and Self-rated Oral Health on Convergence Study

Abstract: 본 연구는 우리나라 성인의 정신건강과 주관적 구강건강과의 관련성을 알아보고자 제5기(2012년) 국민건강영양조사를 이용하여 19세 이상 55세 이하의 성인 3,591명을 연구대상으로 하였다. 정신건강에 따른 주관적 구강건강의 위험도와 95% 신뢰구간은 다변량로지스틱회귀분석을 통해 산출하였으며, 주요결과는 다음과 같다. 본인인지 구강건강상태에서는 스트레스를 많이 받는 경우(OR=1.62; 95% CI=1.36-1.95), 치통경험에서는 2주 이상 연속 우울감이 있는 경우(OR=1.40; 95% CI=1.06-1.85), 저작불편호소경험에서는 정신문제상담 경험이 있는 경우(OR=2.31; 95% CI=1.28-4.18), 악관절 증상경험에서는 2주 이상 연속 우울감이 있는 경우(OR=1.83; 95% CI=1.39-2.42), 말하기 문제의 경우 정신문제 상담을 받은 경우(OR=4.80; 95% CI=2.10-10.94)에서 위험도가 가장 높게 나타났다. 따라서 스트레스인지, 우울증상 경험, 정신문제 상담경험이 주관적 구강건강과 관련성이 있는 것으로 나타났다. 성인의 정신건강을 고려한 구강건강 증진 프로그램을 개발한다면 두 가지 영역에 융합적으로 많은 도움이 될 것으로 생각된다. 【This study is conducted to confirm a correlation between psychological health and self-rated oral health on. 3,591 people aged from 19 to 55 were studied through the Korean National Health and Nutrition Survey. Self-rated oral health risk in relation to psychological health and 95% confidence interval are calculated through multi-variate regression analysis, and the results were as in the following. Self-rated oral health OR was the most when subjects had felt stressed. Toothache experience, OR was the most when subjects had suffered depression more than 2-weeks straight. In terms of mastication problem, OR was the most when subjects had had psychological consultation experience. In terms of TMJ symptom experience, OR was the most when subjects had suffered depression more than 2-weeks straight. In terms of talk problem, OR level was particularly high when subjects had had psychological consultation experience. Therefore, daily stress, depressed conditions, and psychological consultation experience have a correlation with self-rated oral health. developing a oral health promotion program considering psychological health would help those two domains.】

Component-based web application development framework used for creating web page

Abstract: The present invention relates to a user interface server framework and a method of using the framework, which supports a user interface developer to develop a final user interface based on components. The component-based web application development framework used for creating a web page comprises a runtime engine for executing a method of a business object and returning a result of executing the method in response to a user's request; a script component for performing a preprocessing on a user input value before executing the method of the business object, performing a post-processing on the result of executing the method after executing the method of the business object, and dynamically arranging a user interface object; and a core component for initializing the framework and confirming whether the user's request can be processed in the framework.

Method of advertising while playing multimedia content

Abstract: An advertising method and system displaying a context advertisement when the context advertising associated with a contents page which does not match with an advertising keyword or has no text, is provided. The advertising method which displays context advertising information includes: maintaining a context advertising database including the context advertising information; maintaining a user input keyword database including an input query set of keywords inputted by a user; and retrieving and displaying context advertising information associated with the input query set from the context advertising database, when the user visits a contents page which does not match with an advertising keyword or has no text.
