Abstract

This study examined the characteristics of two keyword types expressing the topics in the intellectual structure analysis based on the co-word analysis, focused on overseas open access field. Specifically, the keyword set extracted from the LISTA database in the field of library and information science was divided into two types (controlled keywords and uncontrolled keywords), and the results of performing intellectual structure analysis based on co-word analysis were compared. As a result, the two keyword types showed significant differences by keyword sets, research maps and influences, and periods. Therefore, in intellectual structure analysis based on co-word analysis, the characteristics of each keyword type should be considered according to the purpose of the study. In other words, it would be more appropriate to use controlled keywords for the purpose of examining the overall research trend in a specific field from the perspective of the entire academic field, and to use uncontrolled keywords for the purpose of identifying detailed trends by research area from the perspective of the specific field. In addition, for a comprehensive intellectual structure analysis that reflects both viewpoints, it can be said that it is most desirable to compare and analyze the results of using controlled keywords and uncontrolled keywords individually.

본 연구는 동시출현단어 분석에 기초한 지적구조 분석에서 주제를 표현하는 두 가지 키워드 유형의 특성에 관하여 국외 오픈액세스 분야를 중심으로 살펴보았다. 구체적으로 문헌정보학 분야 LISTA 데이터베이스에서 추출한 키워드 집합을 두 가지 유형(통제키워드, 비통제키워드)으로 구분하고, 동시출현단어 분석에 기초한 지적구조 분석을 수행한 결과를 비교하였다. 그 결과, 각 키워드 유형별로 키워드 집합, 연구지도와 영향력, 그리고 시기에 따라 상당한 차이가 있는 것으로 나타났다. 따라서 동시출현단어 분석에 기초한 지적구조 분석에서는 연구 목적에 따라 키워드 유형별 특성을 고려하여야 한다. 즉 전체 학문분야 관점에서 특정분야의 전반적인 연구 동향을 살펴보는 목적으로는 통제키워드를, 해당 분야 관점에서 연구 영역별로 세부적인 동향을 파악하는 목적으로는 비통제키워드를 사용하는 것이 더 적절할 것이다. 또한 양자의 관점을 모두 반영하는 종합적인 지적구조 분석을 위해서는 통제키워드와 비통제키워드를 개별적으로 사용한 결과를 상호 비교하여 분석하는 것이 가장 바람직하다고 할 수 있다.
