Abstract

The purpose of this study was to find the characteristics of the foreign and domestic travels and to seek out the significance of the study, by grouping the geotweets users who moved abroad, according to the average and the standard deviation of moving distances. Geotweets which caused foreign and domestic travels occurred divided, after building a data mart and the moving distances of users were measured by using the Haversine formula. It has moved more often among groups of foreign travelers in countries that use the same language and have similar lifestyles. There has been a lot of movement in developed countries with well-established infrastructure in a group of domestic travelers. This study tried to draw common features, by calculating the travel distances by each user and grouped users according to the characteristics of user's moving distances. There are significant differences in national economic power, age, jobs, etc. among users from a total of 21 countries analyzed by this study, so a more precise analysis would be able to be conducted, only if the whole conditions are considered. A future study should additionally consider real factors.

본 연구는 국가 간 이동이 발생한 지오트윗 사용자를 이동거리평균과 이동거리표준편차에 따라 그룹화하여, 국가 간 이동과 자국 내 이동에서 나타나는 특징을 발견하고 연구의 의의를 찾고자 하였다. 데이터마트를 구축 후 국가 간 이동과 자국 내 이동이 발생한 지오트윗을 분리하였고, 해버사인공식을 이용해 사용자의 이동거리를 측정하였다. 국가 간 이동 집단에서는 동일한 언어를 사용하며 생활방식이 비슷한 국가 사이에서 많이 이동하였고, 자국 내 이동에서는 인프라가 잘 구축된 선진국 위주의 국가에서 많은 이동이 발생하였다. 본 연구는 사용자별 이동거리를 계산하여 공통된 특징을 도출하고자 하였으며, 사용자의 이동거리 특성에 따라 그룹화하였다. 본 연구에서 분석한 21개국은 국가별 경제력이나 나이, 직업 등에서 차이가 커 많은 제반 사항이 고려되어야 정밀한 분석이 가능할 것이다. 향후에는 현실적인 사항을 추가한 연구가 진행되어야 할 것이다.
