Structuralizing biomedical abstracts with discriminative linguistic features
Nam, S.,Jeong, S.,Kim, S.K.,Kim, H.G.,Ngo, V.,Zong, N. Pergamon Press ; Elsevier Science Ltd 2016 Computers in biology and medicine Vol.79 No.-
Objective: Nearly 75% of the abstracts in MEDLINE papers present in an unstructured format. This study aims to automate the reformatting of unstructured abstracts into the Introduction, Methods, Results, and Discussion (IMRAD) format. The quality of this reformatting relies on the features used in sentence classification. Therefore, we explored the most effective linguistic features in MEDLINE papers. Methods: We constructed a feature set consisting of bag of words, linguistic features, grammatical features, and structural features. In order to evaluate the effectiveness, which is the capability of the sentence classification with the features, three datasets from PubMed Central Open Access Subset were selected and constructed: (1) structured abstract (SA) for training, (2) unstructured RCT abstract (UA-1) and (3) unstructured general abstract (UA-2). F-score and accuracy were used to measure the effectiveness on IMRAD section level and the overall classification. Results: Adding linguistic features improves the classification of the abstract sentence from 1.2% to 35.8% in terms of accuracy in three abstract datasets. The highest accuracies achieved were 91.7% in SA, 86.3% in UA-1, and 77.9% in UA-2. Linguistic features (dimensions=15) had fewer dimensions than bag-of-words (dimensions= 1541). All representative linguistic features (n-gram and verb phrase, and noun phrase) for each section are identified in our system (available at http://abstract.bike.re.kr). Conclusion: Linguistic features can be used to effectively classify sentence with low computation burden in MEDLINE abstract.

이 글의 목적은 포스텍 학생들이 쓴 실험보고서의 분석을 통해서 이공계에 특화된 과학 글쓰기 교육의 방법론을 마련하고자 하는 것이다. 이러한 목적에 도달하기 위해 이 글은 세 단계의 구성을 취한다. 첫째, 이공계에 특화된 글쓰기 교육 시스템 및 연구의 현황을 검토함으로써 실험보고서에 대한 연구와 교육의 필요성을 증명하고자 했다. 둘째, 현재 대다수의 글쓰기 교육 담당자들이 인문사회계열 출신이기 때문에 이공계 실험과목이 어떻게 운영되는지, 실험보고서의 실제는 어떠한지에 대한 정보가 부족하다는 점을 고려하여 이공계 실험과목의 운영체계와 실험보고서의 실제를 살펴보았다. 셋째, 포스텍 1학년 필수과목인 물리실험Ⅱ의 실험보고서에 나타나는 오류의 분석을 바탕으로 이공계열 1학년 학생을 대상으로 한 기초 글쓰기과정에 도입할 수 있는 프로그램을 제안하였다. The purpose of this thesis is to devise the Technical Writing training program for the students in science and engineering departments through the analysis of the experimental reports written by Postech's students. For this goal, this thesis is composed of three steps. First, I tried to demonstrate the necessity of study and education on experimental reports by way of examining writing education system for the students in science and engineering departments. Second, because the major of the most writing educators are the humanities and therefore they don't have necessary informations about experimental class or experimental reports, so I investigated practical experimental reports and the system of experimental class. Third, I suggested the Technical Writing program to train the composition of experimental reports. This program is devised to be applied to the primary writing lecture for the freshman in science and engineering departments.
