개별화 웹 마케팅은 본질적으로 고객지향의 패러다임이다. 즉, 개별 고객의 특수한 니즈를 개별적으로 파악해서 각각의 고객에게 차별화된 서비스를 제공하는 것이 그 핵심이다. 웹 서버의 고객이 접근한 상품의 로그파일에 데이터마이닝의 연관규칙 기술을 이용하게 되면 고객행동 패턴의 파악 및 예측을 위한 기법으로 활용할 수 있다. 본 연구에서는 웹 사용자의 교차 판매를 위한 원투원 마케팅에 필요한 접근패턴을 분석하고자 하며, 이는 고객의 상품에 대한 접근이 기록된 액세스 로그 데이터베이스의 분석을 통하여 이루어진다. 이들 데이터 처리와 교차판매 지원을 위한 데이터마이닝 모델링, 이를 통한 원투원 마케팅 모델 제시, 그리고 이의 활용이 고객관계관리(eCRM)에 미치는 효과를 제시한다.

In a new technological environment such as big data and AI, LOD will link record information resources with various data from both inside and outside. At the heart of this connection is the interlinking technology, and interlinked LOD will realize the opening of record information as the highest level of open data. Given the ever-increasing amount of records, automation through interlinking algorithms is essential in building LODs. Therefore, this paper analyzed the structure of record information interlinking with the external data and characteristics of the record information to be considered when interconnecting. After collecting samples from the CAMS data of the National Archives, we constructed a record information's LOD. After that, we conducted a test bed that automatically interlinks the personal information of the record metadata with DBPedia. This confirms the automatic interlinking process and the performance and accuracy of the automation technology. Through the implications of the testbed, we have identified the considerations of the record information resources of the LOD interlinking process.

The new administrative capital construction project is an important national project implemented to relocate the national administrative capital, and the records produced during the construction have high historical value. However, Korea's management of these records related to the construction of the new administrative capital is insufficient; thus, finding a management plan is necessary. In contrast, Brazil is a country that collects, builds, and maintains both public and private records produced during the construction of Brasilia, the new administrative capital. Thus, Arquivo Publico do Distrito Federal (ArPDF), the Brazilian records management organization established to manage Brasilia's construction records, was selected as the case analysis subject in this study. By analyzing ArPDF's website and official publications, this study investigated the overall matters related to the management of new administrative capital construction records and derived implications applicable to the management of new administrative capital construction records in Korea.

A blog is a website, usually maintained by an individual, with regular entries of commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse chronological order. Blog search engines, like web search engines, seek information for searchers on blogs. Blog search engines sometimes output unsatisfactory results, mainly due to spam blogs or splogs. Splogs are blogs hosting spam posts, plagiarized or auto-generated contents for the sole purpose of hosting advertizements or raising the search rankings of target sites. This thesis focuses on splog detection. This thesis proposes a new splog detection method, which is based on blog post structure similarity and posting count per day. Experiments based on methods proposed a day show excellent result on splog detection tasks with over 90% accuracy.

Location information service using big data is continuously developing. In terms of navigation, the range of services from map API service to ship navigation information has been expanded, and system application information has been extended to SNS and blog search records for each location. Recently, it is being used as a new industry such as location-based search and advertisement, driverless cars, Internet of Things (IoT) and online to offline (O2O) services. In this study, we propose an information system that enables users to receive information about nearby stores more effectively by using big data when a user moves a specific route. In addition, we have designed this system so that local stores can use this system to effectively promote it at low cost. In particular, we analyzed web-based information in real time to improve the accuracy of information provided to users by complementing the data. Through this system, system users will be able to utilize the information more effectively. Also, from a system perspective, it can be used to create new services by integrating with various web services.

RIA(Rich Internet Application) has the best User Interface and easy way to use. It is used in many Application System and Web Application. This Paper introduces a RIA technology for Implementation of u-Hospital Application. This System uses a history of customers in the hospital and question about diseases, so we can improve the satisfaction of service. This paper shows that the u-Hospital System using RIA is more fast and easy than HTML application. Because RIA has special features that data can be obtained from server without reloading entire page and every user interaction does not require web server response. The proposed technology can improve the efficient u-Hospital System because it can be extended to ubiquitous mobile application.

우리는 1 인 가구가 늘어나고 있고 주거 침입 사고도 많이 발생하고 있는 현재 사회에 맞게 도어락에 보안을 강화하고, 집안에 CCTV 를 설치하여 감시하는 서비스를 제공하여 거주자의 불안감을 덜어내도록 한다. 사용한 H/W 는 아두이노와 지문인식센서로 도어락의 지문인증에, 라즈베리파이와 웹 캠은 도어락의 얼굴인증, CCTV 에 사용하여 구축했다. 또한 도어락 인증에 성공하면 집 모형의 문을 열어주기 위해 서보 모터를 사용했다. 사용한 S/W 는 데이터 저장, 얼굴 인증은 AWS 클라우드 서비스를 활용했고, 스마트폰 알람은 FCM 을 사용하였다. OpenCV 를 사용해 움직임 감지를 하고, Flask, Ngrok 를 활용해 실시간 스트리밍이 가능하도록 했다. 어플에서는 관리자가 데이터를 관리(조회, 추가, 삭제)를 할 수 있다.

Recently, the web service environment has changed from document-centered to data-oriented focus, and the Linked Open Data (LOD) exists at the core of the new environment. Specific procedures and methods were examined to build the LOD of records information in accordance with this trend. With the service sustainability of small-scale archive in consideration, an exemplification on LOD building process by utilizing open source software was developed in this paper. To this end, a 5-step service framework for LOD construction was proposed and applied to a collection of diary records from 'Human and Memory Archive'. Proof of Concept (POC) utilizing open source softwares, Protege and Apache Jena Fuseki, was conducted according to the proposed 5 step framework. After establishing the LOD of record information by utilizing the open source software, the connection with external LOD through interlinking and SPARQL search has been successfully performed. In addition, archives' considerations for LOD construction, including improvement on the quality of content information, the role of the archivist, were suggested based on the understanding obtained through the LOD construction process of records information.

최근 e-러닝에서 대두되고 있는 중요한 문제는 곳곳에 산재되어 있는 학습자의 포트폴리오 정보를 표준화 하여 기록하고 이를 학습자의 학습에 다시 활용해야 한다는 것이다. 이를 위해서는 학습자의 포트폴리오의 공유를 위해 포트폴리오의 표준화와 통합 및 관리하는 방법이 필수적이다. 본 연구에서는 개인의 학습이 여러 기관이나 여러 이러닝 사이트를 통해 이루어 지는 상황을 가정하고 포트폴리오를 IMS에서 발표한 ePortfoliio로 표현하며, 이를 Apache Axis를 사용하여 웹 서비스로 관리한다. 기록된 포트폴리오는 필요에 의해 하나로 통합하고 이를 기반한 역량 온톨로지로 변환되어 학습자의 다음 학습에 필요한 콘텐츠를 제시하는 근거로 활용할 수 있도록 하였다.

Dead Link의 노출 최소화는 웹 검색 서비스의 품질 유지에 있어 매우 중요하다. 따라서 색인 내 Soft 404 오류의 정확한 판별은 필수적이지만, 리다이렉션 정보에 의존하거나 텍스트 혹은 HTML 자질 만을 고려하는 기존 방법의 활용만으로는 판별 가능한 Soft 404 오류의 유형이 한정될 수 있다는 문제가 있다. 이에 본 연구에서는 보다 범용성이 높은 Soft 404 오류 판별 기술의 개발을 위해, 404 오류 안내 페이지 고유의 형태적 특성을 오류 판별에 사용할 것을 제안한다. 제안 방법은 오류 안내 문서의 형태적 특성을 이미지 인식 모형에 기반해 학습한 후 이를 Soft 404 오류 판별에 사용하며, 리다이렉션 등 특정 정보에 의존하는 기존 방법에 비해 보다 폭넓게 적용 가능하다는 장점이 있다. 실험에서 제안 방법은 87.6%의 정확률과 92.7%의 재현율을 기록하는 등 높은 인식 성능을 보였다.
