초록

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.

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.
