With the rise of Web 2.0, API-based software has appeared. This article examines the API-based search tool created for the Korean search engine Naver: Webonaver (Webometrics Tool for Naver). The software is able to collect large amounts of data automatically and can easily distinguish between different types of information on the web, which was impossible before. In particular, Internet researchers can improve efficiency of data analysis within a specified timeframe using this tool. This paper illustrates how to use WeboNaver and tries to verify the usability and reliability through several case studies. In this article, Korean National Assembly Members’ web presence was analyzed, as was the web presence of the term H1N1. Web 2.0의 도래와 함께 Open API를 응용한 소프트웨어 프로그램이 등장하면서 더 이상 사용자들은 웹에서 정보를 수동으로 검색하면서 일일이 살펴보는 번거로움을 겪지 않아도 된다. 공개된 API를 활용해 몇 번의 간단한 조작으로 방대한 데이터를 체계적으로 수집하고 관리할 수 있다. 본 논문은 Open API를 응용해 개발한 검색전문 프로그램 WeboNaver(Webometrics Tool for Naver)를 소개한다. 이는 한국에서 가장 영향력 있는 검색엔진 중의 하나인 네이버를 이용해 방대한 데이터를 카테고리별로 자동수집하여 저장해주는 프로그램이다. 연구자들은 이를 활용해 데이터 관리와 처리, 분석 과정에 정확성과 고도의 효율성을 기할 수 있을 것이다. 논문의 목적은 WeboNaver의 사용을 원하는 학생, 일반인, 연구자의 이해를 돕고자 실제 사례들을 통하여 분석절차를 구체적으로 제시해 그 유용성을 입증하는 것이다. 이 프로그램을 사용하여 18대 국회의원 292명의 웹가시성을 조사하였다. 또한 신종플루와 관련된 단어들의 웹 가시성을 분석하였다.

Issues in multiple hits WCU WEBOMETRICS INSTITUTE INVESTIGATING INTERNET-BASED POLITICSS WITH E-RESEARCH TOOLS WCU WEBOMETRICS INSTITUTE INVESTIGATING INTERNET-BASED POLITICSS WITH E-RESEARCH TOOLS The multiple hits reflect the numbers displayed in pages of the Naver. It’s not program error. The Webonaver show actual different numbers of the results from the Naver. The last hits show actual results Webonaver can extract. It’s not the only case of the Naver, but also other search engines such as yahoo display different results as an each webpage.
