Abstract

Measuring nation images was a challenging task when employing offline surveys was the only option. It was not only prohibitively expensive, but too much time-consuming and therefore unfitted to this rapidly changing world. Although demands for monitoring real-time nation images were ever-increasing, an affordable and reliable solution to measure nation images has not been available up to this date. The researcher in this study developed a semi-automatic ontology construction algorithm, named "double-crossing double keyword collection (or DCDKC)" to measure nation images from Wikipedia in real-time. The ontology, WikiOnto, can be used to reflect dynamic image changes. In this study, an instance of WikiOnto was constructed by applying the algorithm to the big-three exporting countries in East Asia, Korea, Japan, and China. Then, the numbers of page views for words in the instance of WikiOnto were counted. A collection of the counting for each country was compared to each other to inspect the possibility to use for dynamic nation images. As for the conclusion, the result shows how the images of the three countries have changed for the period the study was performed. It confirms that DCDKC can very well be used for a real-time nation-image monitoring system.

이 연구에서는 국가이미지를 실시간 측정하기 위하여 위키피디아의 키워드를 추출하여 반자동 동적 온톨로지를 구축하는 알고리즘을 개발하였다. 이 DCDKC (double-crossing double keyword collection)라 명명된 알고리즘에 의해 추출된 국가이미지 온톨로지인 위키온토 (WikiOnto)는 동적으로 변화하는 국가이미지를 실시간으로 자동 측정하여 제공할 수 있도록 하였다. 따라서 국가이미지 관리에 효율성을 기하고 뜻밖에 있을 지도 모르는 국가이미지의 급박한 변화에 선제적으로 대응할 수 있는 도구를 개발하고자 하였다. DCDKC 알고리즘은 과거 오프라인 설문조사에 상당부분 의존하던 각종 국가브랜드지수 모델과는 달리 온라인 실시간 동적 국가이미지 모니터링 시스템에 잘 적용될 수 있음을 보여주었다. DCDKC 알고리즘을 적용한 시스템의 유용성을 검증하기 위하여 아시아의 3대 수출국인 한중일 삼국의 국가이미지를 측정하기 위한 동적 온톨로지 위키온토를 구축하고 국가 이미지의 동적 변화를 실시간으로 추적가능함을 확인하였다. 결론적으로 DCDKC를 이용한 위키온토의 구축을 통한 국가이미지 실시간 관리체계에 대한 가능성을 확인하였을 뿐더러 저렴하고 탁월한 솔류션이 될 수 있음을 증명하였다.
