이 연구는 성격유형별로 선호하는 도서를 추천할 수 있는 키워드를 선별하고, 선별된 키워드가 실제 성격유형별 도서의 구분 및 추천에 활용 가능한지 여부를 밝히는데 목적이 있다. 유효성을 검증하기 위해 초등학생 5~6학년과 중학생 1학년 수준에 맞는 도서를 선정하여, 전문가 집단에 의뢰하여 성격유형별 선호도서로 분류하였다. 분류 결과, 전문가 집단 5인 이상 의견이 일치하는 도서가 절반에 해당하며 높은 일치도를 나타냈다. 또, 선정된 도서의 서평 데이터를 모아 어휘자동추출시스템으로 추출한 키워드로 도서를 성격유형별로 분류한 결과와 전문가 집단이 최종 판정한 결과를 비교하면, 소수의 도서를 제외하고 거의 유사한 결과를 보였다. 이로써 서평 키워드를 활용하여 성격유형별 선호도서로 구분하고, 성격유형별 도서추천에 유효성이 있음을 검증하였다.

현재 軍(육군) 입대 장병은 신병훈련소에서 신체에 대한 치수 측정(자동, 수동) 및 샘플 피복을 착용해 본 후, 희망하는 치수로 피복을 지급받고 있다. 하지만, 민간 평상복보다 상대적으로 매우 세분화된 치수 체계를 적용하고 있는 軍에서는 이와 같은 치수 측정 과정에서 발생하는 측정된 치수의 낮은 정확도로 인해 지급받은 피복이 제대로 맞지 않아 피복을 교체하는 빈도가 매우 빈번히 발생하고 있다. 뿐만 아니라 서구적으로 변화된 MZ 세대의 체형변화를 반영하지 않고, 10여 년 전(前)에 수집된 구세대 체형 데이터 기반의 치수 체계를 적용함으로써 재고량이 비효율적으로 관리되는 문제점이 있다. 즉, 필요한 규격의 피복은 부족하고 불필요한 규격의 피복재고는 다수 발생하고 있다. 따라서, 피복 교체빈도를 감소시키고 재고관리의 효율성을 향상하기 위해 딥러닝 기반의 신체 치수 자동측정과 빅데이터 분석 및 머신러닝 기반의 "입대 장병 개인 맞춤형 피복 자동 추천 시스템"을 제안한다.

데이터베이스 마케팅을 필두로 최근 마케팅 분야에서는 보다 고객에 적합한 제품이나 서비스를 제공하고 또한 이로 인해 그 마케팅 비용을 최소화하고 또한 그 매출효과를 극대화하고자 하는 움직임이 가속화되고 있으며, 극단적으로는 일대일 마케팅이라고까지 표현하고 있다. 더욱이 전자쇼핑몰에 있어서는 실제 판매원이 존재하지 않는 이상 보다 더 고객의 관심을 유도하고 궁극적으로 매출을 발생시키기가 더욱 어려운 실정이며 따라서 고객을 파악하기 또한 그 고객에 적합한 제품이나 서비스에 대한 정보를 즉각적 또는 사전적으로 추측 제시하여야 하는 역량이 매우 중요하다 하겠다. 그러나 이와 같은 즉시성의 추정이나 판단의 유효성을 제고하기 위해서는 전자쇼핑몰 입장에서 일단의 단편적 정보에 의존하는 방식보다는 이용가능한 모든 정보에 대한 통합적 고찰과 또한 고객에 대한 제안 여부와 추천 의사 결정을 개별적이고 순차적인 절차로 보는 관점보다는 하나의 통일된 관점에서 최대의 효과를 발생시킬 수 있도록 하는 상품 추천 방법론이 필요하다 하겠다. 본 연구는 이를 위해 전자쇼핑몰에서의 오프라인/온라인의 통합 정보를 바탕으로 추천 대상 고객 선정 및 추천 효과의 최적화를 목적으로 추천 상품 및 서비스 결정의 의사결정들에 대한 단일 의사결정 방법론 즉 상품 추천 방법론을 제안하며 이를 에이전트 기법을 바탕으로 설계하였다. 또한 이상의 방법론과 설계기법을 국내 유수의 전자쇼핑몰에 적용하여 그 실험적 성과를 제시하고 있다.

Tracking the most recent advances in Coronavirus disease 2019 (COVID-19)-related research is essential, given the disease's novelty and its impact on society. However, with the publication pace speeding up, researchers and clinicians require automatic approaches to keep up with the incoming information regarding this disease. A solution to this problem requires the development of text mining pipelines; the efficiency of which strongly depends on the availability of curated corpora. However, there is a lack of COVID-19-related corpora, even more, if considering other languages besides English. This project's main contribution was the annotation of a multilingual parallel corpus and the generation of a recommendation dataset (EN-PT and EN-ES) regarding relevant entities, their relations, and recommendation, providing this resource to the community to improve the text mining research on COVID-19-related literature. This work was developed during the 7th Biomedical Linked Annotation Hackathon (BLAH7).

According to the increase of internet application, the marketing process as well as the research and survey, the education process, and administration of government are very depended on web bases. All kinds of goods and sales which are traded on the internet shopping malls are extremely increased. So, the necessity of automatically intelligent information system is shown, this system manages web site connected users for effective marketing. For the recommendation system which can offer a fit information from numerous web contents to user, we propose an automatic recommendation system which furnish necessary information to connected web user using statistical learning theory and bayesian fuzzy clustering. This system is called collaborative CRM in this paper. The performance of proposed system is compared with the other methods using real data of the existent shopping mall site. This paper shows that the predictive accuracy of the proposed system is improved by comparison with others.

Automatic document classification may differ significantly according to the characteristics of documents that are subject to classification, as well as classifier's performance. This research identifies e-mail document's characteristics to apply a three-step preprocessing algorithm that can minimize e-mail document's atypical characteristics. In the first 5go, uncertain based sampling algorithm that used Mean Absolute Deviation(MAD), is used to address the question of selection learning document for the rule generation at the time of classification. In the subsequent stage, Weighted vlaue assigning method by attribute is applied to increase the discriminating capability of the terms that appear on the title on the e-mail document characteristic level. in the third and last stage, accuracy level during classification by each category is increased by using Naive Bayesian Presumptive Algorithm's Dynamic Threshold. And, we implemented an E-Mail Recommendtion System using a three-step preprocessing algorithm the enable users for direct and optimal classification with the recommendation of the applicable category when a mail arrives.

Computer-Assisted Pronunciation Training system is considered to be a useful tool for pronunciation learning for students who received elementary level English pronunciation education, especially for students who have difficulty in correcting their pronunciation in front of others or who are not able to receive face-to-face training. The conventional Computer-Assisted Pronunciation Training system shows the word to the user, the user pronounces the word, and then the system provides phoneme or audio feedback according to the pronunciation of the user. In this paper, we propose a Computer-Assisted Pronunciation Training system that can practice on the varying pronunciation according to positions of adjacent phonemes. To achieve this, the proposed system is implemented by recommending a series of words by focusing on adjacent phonemes for simplicity and clarity. Experimental results showed that word recommendation considering adjacent phonemes leads to improvement of pronunciation accuracy.

Because the quantitative relationships between welding parameters and welding result are not yet blown, optimal values of welding parameters for $CO_2$ robotic arc welding is a difficult task. Using the various artificial data processing methods may solve this difficulty. This research aims to develop an expert system for $CO_2$ robotic arc welding to recommend the optimal values of welding parameters. This system has three main functions. First is the recommendation of reasonable values of welding parameters. For such work, the relationships in between the welding parameters are investigated by the use of regression analysis and fuzzy system. The second is the estimation of bead shape by a neural network system. In this study the welding current voltage, speed, weaving width, and root gap are considered as the main parameters influencing a bead shape. The neural network system uses the 3-layer back-propagation model and a generalized delta rule as teaming algorithm. The last is the optimization of the parameters for the correction of undesirable weld bead. The causalities of undesirable weld bead are represented in the form of rules. The inference engine derives conclusions from these rules. The conclusions give the corrected values of the welding parameters. This expert system was developed as a PC-based system of which can be used for the automatic or semi-automatic $CO_2$ fillet welding with 1.2, 1.4, and 1.6mm diameter the solid wires or flux-cored wires.
