초록
과학에서 지식의 불확실성은 명제가 현재 상태로는 참도 거짓도 아닌 불확실한 상태를 의미한다. 기존의 연구들은 학술 문헌에 표현된 명제를 분석하여 불확실성을 의미하는 단어를 수동적으로 구축하고 구축한 코퍼스를 대상으로 규칙 기반, 기계 학습 기반의 성능평가를 수행해왔다. 불확실성 단어 구축의 중요성은 인지하고 있지만 단어의 의미를 분석하여 자동적으로 확장하고자 하는 시도들은 부족했다. 한편, 계량정보학이나 텍스트 마이닝 기법을 이용하여 네트워크의 구조를 파악하는 연구들은 다양한 학문분야에서 지적 구조와 관계성을 파악하기 위한 방법으로 널리 활용되고 있다. 따라서, 본 연구에서는 기존의 불확실성 단어를 대상으로 Word2Vec을 적용하여 의미적 관계성을 분석하였고, 영어 어휘 데이터베이스이자 시소러스인 WordNet을 적용하여 불확실성 단어와 연결된 상위어, 하위어 관계와 동의어 기반 네트워크 분석을 수행하였다. 이를 통해 불확실성 단어의 의미적, 어휘적 관계성을 구조적으로 파악하였으며, 향후 불확실성 단어의 자동 구축의 확장 가능성을 제시하였다.

Abstract
Uncertainty in scientific knowledge means an uncertain state where propositions are neither true or false at present. The existing studies have analyzed the propositions written in the academic literature, and have conducted the performance evaluation based on the rule based and machine learning based approaches by using the corpus. Although they recognized that the importance of word construction, there are insufficient attempts to expand the word by analyzing the meaning of uncertainty words. On the other hand, studies for analyzing the structure of networks by using bibliometrics and text mining techniques are widely used as methods for understanding intellectual structure and relationship in various disciplines. Therefore, in this study, semantic relations were analyzed by applying Word2Vec to existing uncertainty words. In addition, WordNet, which is an English vocabulary database and thesaurus, was applied to perform a network analysis based on hypernyms, hyponyms, and synonyms relations linked to uncertainty words. The semantic and lexical relationships of uncertainty words were structurally identified. As a result, we identified the possibility of automatically expanding uncertainty words.
