초록
불확실성이란 정보의 합의나 현존하는 지식 부족으로 인해 명제의 지식이 불완전한 상태를 의미한다. 과학적 지식의 불확실성을 연구하는 학술문헌의 양은 시간이 흐름에 따라 기하급수적으로 증가하고 있으며, 이에 따라 새로운 지식이 발견되고 연구가 발전하고 있다. 이처럼 시간의 흐름은 지식의 불확실성의 패턴을 발견하는데 중요한 요인이 될 수 있음에도 불구하고 기존의 연구들은 불확실성 단어의 단순 출현 빈도를 기반으로 특정 학문 영역에서 불확실성의 특성을 파악해왔다. 따라서, 본 연구에서는 구축한 불확실성 단어를 생의학 영역의 불확실성 연구에 적용하여 시간의 흐름에 따른 불확실성의 변화와 패턴을 파악하고자 한다. 시간의 흐름에 따른 생의학 지식의 패턴을 분석하기 위해 대표 개체 페어, 동사 유형, 대표 개체의 패턴을 살펴보았으며 선형 회귀 분석을 통해 유의성 검증을 수행했다. 개체 페어 분석에서는 17건 중 7건의 개체 페어가 유의하게 감소하는 패턴을 보였다. 10개의 대표적인 동사 유형은 모두 시간이 흐름에 따라 유의하게 감소했다. 대표 개체의 연도별 상대적 중요도 분석에서는 유의하게 상승과 하강 패턴을 보이는 개체들의 불확실성 증감을 분석했다.
Abstract
Uncertainty means incomplete stages of knowledge of propositions due to the lack of consensus of information and existing knowledge. As the amount of academic literature increases exponentially over time, new knowledge is discovered as research develops. Although the flow of time may be an important factor to identify patterns of uncertainty in scientific knowledge, existing studies have only identified the nature of uncertainty based on the frequency in a particular discipline, and they did not take into consideration of the flow of time. Therefore, in this study, we identify and analyze the uncertainty words that indicate uncertainty in the scientific literature and investigate the stream of knowledge. We examine the pattern of biomedical knowledge such as representative entity pairs, predicate types, and entities over time. We also perform the significance testing using linear regression analysis. Seven pairs out of 17 entity pairs show the significant decrease pattern statistically and all 10 representative predicates decrease significantly over time. We analyze the relative importance of representative entities by year and identify entities that display a significant rising and falling pattern.
