Abstract

This study aims to provide information about the research-trends in the area of Geospatial Information using text-mining methods. We derived the National R&D Reports and papers from NDSL(National Discovery for Science Leaders) site. And then we preprocessed their key-words and classified those in separable sectors. We investigated the appearance rates and changes of key-words for R&D reports and papers. As a result, we conformed that the researches concerning applications are increasing, while the researches dealing with systems are decreasing. Especially, with in the framework of the keyword, '3D-GIS', 'sensor' and 'service' xcept ITS are emerging. It could be helpful to investigate research items later.

본 연구의 목적은 텍스트마이닝 기법을 활용하여 공간정보 분야의 연구동향을 파악하는 것이다. 이를 위하여 국가과학기술도서관에서 국가연구개발보고서와 논문을 추출하여 키워드에 대한 전처리를 수행한 후 분야별로 정리하였다. 정리된 키워드들을 통해 보고서 및 논문에서 키워드의 시기별 출현 빈도 및 변화를 살펴보고 이를 통해 공간정보 분야의 연구동향을 확인하였다. 분석결과 공간정보 분야에서는 시스템 관련 연구가 줄어드는 반면 활용 관련 연구가 늘어가는 추세가 있음을 확인하였다.
