XML Web Service is a new distributed computing paradigm for combining all computer systems through the on-line standardized open network, so it is expected that companies can get the results of increasing profits and reducing costs through this. Especially XML Web Service is essential in mobile environment. In this paper, a new XML Web Service is proposed and it is based on WIPI-based XML standard technology and mobile web service standard. The proposed XML Web Service embodied XML Parser which can be used in WIPI environment and made HTTP communication. In addition, as an example of the practical application, it was applied to an inventory Management, Book Store using JAVA language for WIPI.

M2M can provide the bi-directional services between applications and objects which have the attached telecommunication module. It consists of the objects, platform, and (web based) applications. M2M can realize In-Transit Visibility and Asset Visibility combined with GIS. Although many applications of M2M, such as metering, monitoring, controlling, tracking et al., are being serviced, the interoperability among the M2Ms is not considered. In this paper, we described the interoperability. Specially, ROA, which is the state of art technology in mash-up, more than SOA, and URN, which is based on Open API in RESTful service, more than URL are studied. As the message protocol between platform and applications, MPM was defined.

We classify SNS into two categories and describe the merits and demerits of them. In order to combine the merits of each kind of SNS, we propose the social information sharing system for social network service using social content channel. It makes user share information faster and gather information more effectively. In this paper, we present AskMyFriend. It opens a channel aggregating users' interaction and recommends person who is most likely to know about topic of the question.

GeoRSS is RSS which contains geospatial information, and it supports to supply diverse kinds of data through mash-up map service like the google map. It helps to implement efficient web service with simple java-scripts, but sometimes initial page loading takes too much time and causes heavy traffic when it includes lots of multimedia data. In this paper, we propose a splitting method of GeoRSS for fast accessing. As the result of experiments, we achieved improvement of browsing speed and reducing of initial data traffic.

본 논문은 오픈 API를 이용하여 다국어 정보검색 시스템을 모델링하는 방법론을 제시한다. 웹 2.0이 대두되면서 웹 2.0의 개념을 활용한 기술들이 발달하고 있는데, 그 중 한 기술이 오픈 API이다. 기업에서 개발한 새로운 서비스나 기능, 데이터 등을 API로 공개함으로써 사용자들이 공개된 API를 이용하여 새로운 서비스를 쉽게 개발할 수 있게 되었다. 본 연구에서는 구글, 플리커, 유튜브, 네이버, 다음 등의 사이트에서 제공하는 오픈 API를 이용하여, 다국어 정보 검색 시스템을 구현하였다. 구글 번역 API를 이용하여 한국어 질의어를 검색 대상 언어(영어, 일본어, 중국어 등)로 번역한 후, 소설 웹 사이트(플리커, 유튜브, 다음, 네이버 등)의 정보를 검색하고, 검색된 결과 내 텍스트를 다시 한국어로 번역한 후, 통합된 검색 결과를 사용자에게 보여준다.

매쉬업은 공개된 Open API들을 이용하여 두 가지 이상의 서로 다른 자원을 섞어서 완전히 새로운 가치의 서비스를 만드는 것이다. 매쉬업은 미래 IT 융합 서비스의 효과적인 구현 방법으로써 그 관심도가 점점 높아지고 있으나 컴퓨팅 파워가 떨어지는 스마트폰 환경에서 매쉬업을 성공적으로 개발하기 위해서는 한정된 스마트폰 성능과 고성능 무선 인터넷 활용에 대한 이슈들을 고려해야만 한다. 본 논문에서는 다양한 Open API들을 이용하여 스마트폰에서 활용 가능한 위치기반 모바일 매쉬업을 개발한다. 이는 클라우드 컴퓨팅 개념을 접목하여 별도의 솔루션을 구축하지 않고도 저비용 고효율적으로 스마트폰 응용 프로그램을 제작할 수 있는 방법을 제시하고 있다.

2.0 시대에 도래하면서 웹에 대한 새로운 패러다임이 생성되었다. 이러한 웹 2.0의 주요 기술은 OpenAPI인데, OpenAPI는 간단한 프로토콜로 정의되어 사용되기 때문에 많은 사용자들이 손쉽게 서비스를 만들 수 있는 장점이 있다. 하지만 빠르게 증가하는 OpenAPI를 효과적으로 검색할 수 있는 여전히 연구중이다. 본 논문은 이러한 OpenAPI에 대해 키워드 기반 검색보다 한단계 발전한 시맨틱 기반의 검색을 제공하기 위해 관련 표준 및 기술에 대해 설명하였다. 이러한 시맨틱을 활용한 OpenAPI의 검색기법은 OpenAPI를 통해 많이 사용되는 매쉬업(Mashup)을 위한 서비스 검색에도 활용될 수 있다.

This research proposes a prototype for visualizing radar rainfall data using the unity 3D engine. The mashup of radar data with topographic information is necessary for the 3D visualization of the radar data with high quality. However, the mashup of a huge amount of radar data and topographic data causes the overload of data processing and low quality of the visualization results. This research utilized the Unitiy 3D engine, a widely used engine in the game industry, for visualizing the 3D topographic data such as the satellite imagery/the DEM(Digital Elevation Model) and radar rainfall data. The satellite image segmentation technique and the image texture layer mashup technique are employed to construct the 3D visualization system prototype based on the topographic information. The developed protype will be applied to the disaster-prevention works by providing the radar rainfall data with the 3D visualization based on the topographic information.

Recently many of earlier GIS services are changing to the form of user-participated dynamic geoweb service like many new impressive web 2.0 services substitute for earlier old-fashioned web 1.0 services. Many relevant technologies are necessary to be developed so as to integrate a number of geospatial data and functions all around into the useful geoweb services. It is also necessary to make the integration easy and to cope with the rapid changes in geoweb environment. In this study, the trend of relevant geoweb technologies were reviewed before, and the development of open geospatial service platform were carried out. As a result, open 2D/3D map service engine, user-participated mashup engine, Open API search engine and so on were im plemented as the core components of that platform. The platform will be able to be used as the common platform among a number of applications in the fields such as public/private GIS integration, u-city projects and GIS/LBS services etc.

This paper introduces a new search model which can retrieve information instantly and easily about a given search word on Internet and control search spaces diversely. In the existing web searches, because the user has to stop his work, run web browsers, connect to special internet sites, and type the search word by keyboard. it is a long way and not a simple way. Also the search result is too much. The user suffers difficulties of multiple searches for different categories such as dictionary, image, video clips, etc. The software implemented in this paper enables for the user to select search word simply at any documents on the screen and make search started by simply pressing CRTL key and left button of the mouse simultaneously. The software is a mash up style using the Open API which is provided by a web site and can be freely available in any other sites. By calling different Open APIs of several web sites, the mash-up software can integrate search functions of many different sites. We evaluate that the software implemented in this paper will be a good reference of mash-up as one with characteristics of easy and instant search, simple result, diversity of search category, and scalability of search functions.
