Abstract

Since realtime search keywords of portal sites are arranged in descending order by instant increasing rates of search numbers, they easily show issues increasing in interests for a short time. But they have the limits extracted different results by portal sites and not shown issues by a period. Thus, to find key issues from the whole realtime search keywords for certain period, and to show results of summarizing them and analyzing differences, is significant in providing the basis of understanding issues more practically and in maintaining consistency of them. This paper analyzes differences of week key issues extracted from week analysis of realtime search keywords provided by two typical portal sites. The results of experiments show that the portal group means of realtime search keywords by the independent t-test and the survival functions of realtime search keywords by the survival analysis are statistically significant differences.

포털사이트의 실시간 검색키워드는 검색횟수의 순간증가율이 높은 순서대로 나타나므로 짧은 시간에 관심도가 급상승하는 이슈는 쉽게 보여주지만, 포털사이트별로 다른 결과가 도출되고 일정기간에 대한 이슈는 나타내지 못하는 한계가 있다. 따라서, 일정기간 동안의 전체 실시간 검색키워드에서 핵심 이슈를 찾고 각 포털사이트별로 집계한 결과와 이들의 차이를 분석한 결과를 보여주는 것은 이슈를 보다 실제적으로 이해할 수 있는 근거를 제공하고 자주 변화하는 실시간 검색키워드에 대한 일관성을 유지할 수 있게 해준다는 측면에서 의미가 있다. 이를 위해 본 논문에서는 대표적인 두 개의 포털사이트에서 제공하는 실시간 검색키워드의 주간 분석을 통하여 주간 핵심 이슈를 추출하고 이들의 차이를 분석한다. 두 포털사이트의 실시간 검색키워드 중요도 점수에 대한 독립표본 t검정과 실시간 검색키워드 생존함수에 의한 생존분석 결과, 두 포털사이트는 차이가 있다는 것을 보였다.
