As the trend of the Web is changing toward 'Web 2.0', OpenAPIs, Web 2.0's core technology, are used in many web sites. In the past, services in websites are used in its own, but recently it is possible to use services in other websites by using OpenAPI. In u-GIS many vendors also can provide combined service by using OpenAPI. There are already lots of OpenAPIs and the numer of OpenAPI increases very fast. So it is difficult to find a service that we want to use, and also difficult to find services for mashup. In this paper, we developed retrieval methods for OpenAPIs and mashup capable services based on similarity. First we define the integrated service information model to cover various protocols of OpenAPI, then developed a retrieval methods based on it. By implementing system according these methods by using relational database and JSP, we prove that the system can provide an ranked result sets based on similarity, OpenAPI's integration retrieval results and mashup capable service retrieval results.

This paper studied and proposed a XML document storing-and-retrieval framework based on a variant k-ary complete tree and a RDF metadata, which is composed of an effective storing module to store xml documents, a retrieving module to retrieve xml documents, and a connecting module to make this system intemperate in the web environment. In this storing module, DTD independent DOM based decomposition model using a method of addressing unique ill using a variant k-ary complete tree is adopted and is implemented. Query Processing Module includes a XPath query process and a content based retrieval function using word index for content information. To retrieve more exactly data, a structural retrieval using RDF metadata is adopted and implemented. In order to implement effectively XML document storing and retrieval system in the web environment, API using XML-RPC, API using HTTP's GET, PUT, POST and API using SOAP have been adopted and implemented.

Web based simulation service is utilized to computationally analyze various phenomena in real world according to the progress of network and computing technology. To provide suitable simulation service, web based simulation service will be improved by analyzing execution data. Especially, an API for data retrieval is designed, because every analyst needs different data. In this paper, we design the retrieval API for a user to analyze the web based simulation execution data, which is used on CFD (Cumputational Fluid Dynamics) and Chemistry. The designed retrieval API provides an simulation execution data depending on an user requirement such as a user type, an execution period, and an affiliation, which is based on the core information such as an user, a simulation program, and a cyberlab. Besides, a developer can provides a suitable information for a user to execute a simulation well such as a simulation statistics, an execution trend, and a frequent error.

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.

In recent years, several technologies have brought many changes in the field of education. Nonetheless, it is difficult to get freely medical and professional knowledge in the educational environment. In this paper, we study a free medical education system for medical education through service to the Mashup offers a meta-search system. Received permission to use the system API to retrieve the content API, data retrieval systems and video content via the API to design a system, based on this medical education, meta-search system is implemented.

The Semantic Web enables machines to achieve an effective retrieval, integration, and reuse of web resources. The keyword search method currently used has a limit to accurate search results because of a simple string matching method in web environment. This paper proposes an Ontology-Based Information Retrieval which can solve the problems and retrieve better search results through semantic relations. In this system, we implemented the Cultural Assets Ontology based on OWL with RDQL and Jena API. we also suggest a method to handle properties stored in a database.

WebChemDB is an integrated chemical database retrieval system that provides access to over 8 million publicly available chemical structures, including related information on their biological activities and direct links to other public chemical resources, such as PubChem, ChEBI, and DrugBank. The data are publicly available over the web, using two-dimensional (2D) and three-dimensional (3D) structure retrieval systems with various filters and molecular descriptors. The web services API also provides researchers with functionalities to programmatically manipulate, search, and analyze the data.

본 논문은 시맨틱 기술을 활용한 OpenAPI 조합가능 서비스 검색 기법 개발을 위해 관련 연구들을 분석하여 적용방안을 도출하였다. OpenAPI 조합가능 서비스 검색이란 선택된 서비스의 출력과 매칭이 되는 입력을 가진 서비스나 선택된 서비스의 입력과 매칭되는 출력을 가진 서비스를 찾는 것이다. 본 논문에서는 기존의 키워드 기반의 조합 가능 서비스 검색 기법의 한계를 시맨틱 기술을 활용하여 해결하기 위한 관련연구로 SAWSDL-MX2와 LOG4SWS.KOM에 관한 논문들을 분석했다. SAWSDL-MX2에서는 세가지 매칭 기법과 이에 따른 유사도 분석 기법을 제시하였고, LOG4SWS.KOM에서는 두가지 매칭 기법과 이에 따른 유사도 분석 방법을 제시하였다. 관련 연구들에서 분석된 내용을 바탕으로 OpenAPI 조합 가능 서비스에 대한 매칭 기법의 정의, 유사도 분석 기법의 정의가 추후 진행되어야 한다.

인터넷의 발전으로 인터넷을 통해 미디어 콘텐츠를 제공하는 OTT 서비스의 이용자가 점점 증가하고 있다. 본 논문에서는 OTT 서비스 이용자의 검색 편의성을 위한 Vision API를 활용한 영상 속 랜드마크 검색 시스템을 제안한다. 이는 영상을 시청하는 사용자가 영상을 보다가 궁금한 장소가 있으면 따로 검색하지 않고, 바로 해당 장소의 정보를 얻도록 하는 것이다. 본 논문에서 개발한 영상 속 랜드마크 검색 시스템은 사용자가 원하는 영상을 검색 및 재생할 수 있고 재생 중 바로 화면을 캡처할 수 있다. 해당 캡처 이미지를 랜드마크를 기계 학습한 Vision API를 통해 어떤 랜드마크인지 파악하고 결과를 표시한다, 또한 동일 영상에서 다른 사용자가 검색한 이력이 있는 경우 이력을 표시하여주며, 검색한 랜드마크가 나온 다른 영상을 검색하여 보여준다.

The SQL CLl (Call Level Interface) is a database application programming interface (API) that fits the client-server environment, and its de facto standards such as ODBC and JDBC are widely employed in various applications. The current SQL CLl standards, however, do not specify enough features for efficient retrieval of large objects (LOBs) that constitute the multimedia data. In this paper, we propose the LOB caching through the SQL CLl and describe the extension of the SQL eLl to achieve such a goal. We implement our proposal by extending the SQL CLl library for BADA - II DBMS developed at ETRI, and evaluate the performance of LOB retrieval through the cache compared to that of LOB retrieval conducted solely with the functions specified in the current SQL CLl standards.
