    12. 12. Pilot comparison between API and Manual Webpage search WCU WEBOMETRICS INSTITUTE INVESTIGATING INTERNET-BASED POLITICSS WITH E-RESEARCH TOOLS WCU WEBOMETRICS INSTITUTE INVESTIGATING INTERNET-BASED POLITICSS WITH E-RESEARCH TOOLS Comparison was done using randomly selected Korean politicians as of 12 Aug 2009
    13. 13. <ul><li>There are always differences between the API’s results and the normal search results, but these are miniscule differences in comparison with the APIs of Google, Yahoo and Bing </li></ul>Pilot comparison between API’s and Manual WCU WEBOMETRICS INSTITUTE INVESTIGATING INTERNET-BASED POLITICSS WITH E-RESEARCH TOOLS WCU WEBOMETRICS INSTITUTE INVESTIGATING INTERNET-BASED POLITICSS WITH E-RESEARCH TOOLS

    15. 15. 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.

    19. 19. Output file WCU WEBOMETRICS INSTITUTE INVESTIGATING INTERNET-BASED POLITICSS WITH E-RESEARCH TOOLS WCU WEBOMETRICS INSTITUTE INVESTIGATING INTERNET-BASED POLITICSS WITH E-RESEARCH TOOLS The Naver API doesn't provide the real URL. Rather it supplies a 'Naver API’. But, user can visit an actual site when they put the api-based URL to the window browser of the Naver.
    20. 20. <ul><li>There are programming and time issues, but there are also issues regarding how service provider responds. </li></ul><ul><li>Naver is more protective of handing out API keys, in comparison with yahoo or Bing which provide Open APIs. </li></ul><ul><li>It is important that services are not abused. </li></ul>Ethical issues WCU WEBOMETRICS INSTITUTE INVESTIGATING INTERNET-BASED POLITICSS WITH E-RESEARCH TOOLS WCU WEBOMETRICS INSTITUTE INVESTIGATING INTERNET-BASED POLITICSS WITH E-RESEARCH TOOLS
