Abstract

The study is to investigate research trends and knowledge structures in the Smart Farm field. To achieve the research purpose, keywords and the relationship among keywords were analyzed targeting 104 Korean academic journals related to the Smart Farm in KCI(Korea Citation Index), and topics were analyzed using the LDA Topic Modeling technique. As a result of the analysis, the main keywords in the Korean Smart Farm-related research field were 'environment', 'system', 'use', 'technology', 'cultivation', etc. The results of Degree, Betweenness, and Eigenvector Centrality were presented. There were 7 topics, such as 'Introduction analysis of Smart Farm', 'Eco-friendly Smart Farm and economic efficiency of Smart Farm', 'Smart Farm platform design', 'Smart Farm production optimization', 'Smart Farm ecosystem', 'Smart Farm system implementation', and 'Government policy for Smart Farm' in the results of Topic Modeling. This study will be expected to serve as basic data for policy development necessary to advance Korean Smart Farm research in the future by examining research trends related to Korean Smart Farm.

본 연구의 목적은 토픽모델링과 언어네트워크분석을 활용하여 한국의 스마트팜 분야 연구 동향과 지식구조를 파악하는 것이다. 연구목적을 달성하기 위하여 KCI(Korea Citation Index)의 스마트팜 관련 국내 학술지 104편을 대상으로 핵심어와 핵심어들의 연결 관계를 분석하고, LDA 토픽모델링 기법을 이용하여 연구주제와 관련된 토픽들을 분석하였다. 언어네트워크분석 결과, 국내 스마트팜 관련 연구 분야의 주요핵심어는 '환경', '시스템', '사용', '기술', '재배' 등이 나타났으며, 연결중심성, 매개중심성, 위세중심성 결과도 제시하였다. 토픽모델링분석결과, Topic 1은 '스마트팜 도입 분석', Topic 2는 '친환경 스마트팜과 스마트팜의 경제적 효율성', Topic 3은 '스마트팜 플랫폼 설계', Topic 4는 '스마트팜 생산 최적화', Topic 5는 '스마트팜 생태계', Topic 6은 '스마트팜 시스템 구현', Topic 7은 '스마트팜 관련 정부 정책'으로 나타났다. 본 연구는 국내 스마트팜 관련 연구 동향을 살펴봄으로써, 향후 국내의 스마트팜을 발전시키는 데 필요한 정책개발과 연구 방향성을 설정하는데 기초자료가 될 것으로 기대한다.
