Abstract

It became important to develop a wrapper for web information sources due to prevalence of information services through web information sources. We present a wrapper prototype that is a middleware to integrate web information sources. We present the derivation strategy of XML Schema from HTML documents and the query processing method based on XQJ. The usage example of wrapper API will show the usefulness of our prototype system.

최근 웹 정보원에서 제공하는 정보가 정보서비스의 주류를 이루면서 웹 정보원 랩퍼 개발의 중요성이 크게 부각되었다. 본 논문은 웹 정보원을 통합하기 위한 미들웨어로서의 웹 랩퍼를 설계, 구현한 결과를 제시한다. 특히 HTML 문서로부터 XML 스키마로 변환하는 방법을 제시하고, XQuery 질의어에 대한 파서와 XQJ 기반의 질의처리 과정을 제시한다. 그리고 개발된 랩퍼 API의 사용 예를 통하여 그 유용성을 보인다.
