Twitter has been a popular social media platform where people post short messages of 140 characters or less via the web. A hashtag is a word or acronym created by Twitter users to open a discussion about certain topics and issues that have a very high percentage of trending. Since the hashtag posts are sorted by time, not relevancy, people who firstly use Twitter have had difficulty understanding their context. In this paper, we propose a HBase-based automatic summary system in order to reduce the difficulty of understanding. The proposed system combines an automatic summary method with a fuzzy system after storing the streaming data provided by Twitter API to the HBase. Throughout this procedure, we have eliminated the duplicate of contents in the hashtag posts and have computed scores between posts so that the users can access to the trending topics with relevancy.

The opinion mining is that to use the existing data mining technology also uploaded blog to web, to use product comment, the opinion mining can extract the author's opinion therefore it not judge text's subject, only judge subject's emotion. In this paper, published opinion mining algorithms and the text using speech recognition API for non-voice data to judge the emotions suggested. The system is open and the Subject associated with Google Voice Recognition API sunwihwa algorithm, the algorithm determines the polarity through improved design, based on this interview, speech recognition, which implements the model.

This paper describes an advanced unified communication system. The advanced unified communications mean a service that integrates basic communications such as call, SMS, email, and chatting with social networking service considered as a new communication channel, presenting a unified user interface. The advanced unified communication system is composed of advanced UC(Unified Communications) applications, open UC service platform, and UC back-end servers. The advanced UC applications consist of web-based application and smart phone application. The open UC service platform provides a variety of service components that enable the third party applications to access basic communications and social network services within an enterprise. The UC back-end servers provide server functionalities for call, SMS, email, and chatting.

Microsoft released motion sensing device named Kinnect on early 2010, which is available for developing Xbox 360 game and entertainment software. Also many third party libraries and applications are developed for Kinnect. In this paper, we studied and developed guitar rhythm game on Kinnect using three sensor units on it. Rhythm game is the most popular game genre for many game devices including PC, console device, and smart phone. The main reasons for their popularity depends on their simplicity, short learning time and physical activity with rhythms. We developed the game screen and layout on DirectX 11, also we used OpenNI library for recognize physical activity of gamer's body and fingers, and OpenGL for body gestures on the game.

본 연구에서는 각종 웹사이트와 이메일을 통해 전달되는 회의공지에 포함된 회의장소를 나타내는 문자열로부터 실제 위치를 추정하는 시스템을 설계 및 구현하였다. 직접 구현한 NER과 Relation-type Classification 모듈을 사용하였으며, 장소에 대한 모델은 기존의 지리정보시스템들과의 상호 운용성을 위하여 OpenStreetMap[6]과 Geonames[7]의 데이터 구조를 참조하여 설계되었고, 실제 위치를 구하기 위하여 내부자원 외에도, 각종 오픈API들을 외부자원으로 활용하였다.

WWW의 편리한 인터페이스, 뛰어난 접근성과 공유성으로 인해 웹을 이용한 GIS 서비스는 필수적으로 여겨지고 있으며, 기존의 다양한 시스템간의 상호 운용성 또한 점점 강조되어 지고 있다. 웹을 이용한 GIS 서비스를 제공하기 위해서는 1) 기존에 구축되어 있는 다양한 GIS 서버를 이용할 수 있어야 하며, 2) 방대한 양의 지도 데이타 전송으로 인한 응답시간 지연을 해결해야 한다. 이 논문에서는 Open API를 이용한 개방형 클라이언트와 클라이언트에서의 지도 데이터 캐슁 메카니즘을 제시한다. 본 논문에서 제시하는 WWW 기반 GIS는 소프트웨어간의 분산 객체 기술인 CORBA를 이용하는 3계층 구조이다.

장애인은 정보 접근 제한과 편의시설 부족의 요인 등으로 인하여 여행 참여율이 낮아 비장애인과 동일한 여행 서비스를 경험하기에 어려움이 있다. 본 연구에서는 장애 요소 조건을 기반으로 가중기반의 알고리즘에 따라 콘텐츠를 추천하는 서비스를 제안하고 이에 따른 애플리케이션을 구현한다. 기존의 흩어져있던 여행지에 관한 정보와 지도 Open API를 이용하여 여행지에 대해 추천을 하는 애플리케이션 개발을 기획한다. 비장애인은 가중 조건과 관계없이 장애인의 경우에는 장애의 분류, 그 경도에 따라 여행 시 고려해야 할 조건에 따른 가중치를 두어 여행콘텐츠를 상단에 띄어 추천해 주는 방식에 대한 연구 결과를 제공하여 누구든 비장애 여행이 가능해지도록 한다.

Along with the growth of Blockchain, DApp (Distributed Application) is getting attention. As interest in DApp grows, market size continues to grow and many developers participate in development. Many developers are using API(Application Programming Interface) services to mediate Blockchain nodes, such as Infura, for DApp development. However, when using such a service, there is a serious risk that the API service operator can violate the user's privacy by 1 to 1 matching the account address of the Transaction executed by the DApp user with the IP address of the DApp user. It can have an adverse effect on the reliability of public Blockchains that need to provide users with a secure DApp service environment. The proposed Blockchain platform is expected to provide user privacy protection from API services and provide a reliable DApp use environment that existing Blockchain platforms did not provide. It is also expected to help to activate DApp and increase the number of DApp users, which has not been activated due to the risk of an existing privacy breach.
