KoreaMed MeSH 반자동 색인 시스템이 논문 제목, 초록 그리고 저자키워드를 활용하여 부여한 KoreaMed MeSH 체크태그와 NLM의 MeSH 색인전문가가 부여한 MEDLINE MeSH 체크태그와의 일치여부를 비교 분석하였다. KoreaMed 학술지중에서 MEDLINE에 등재된 15종 학술지의 2012년 마지막 호에 실린 논문 236편을 표본으로 선정하여 일치도를 분석한 결과 MEDLINE MeSH 체크태그와 KoreaMed MeSH 체크태그와의 일치율은 30.24%였다. 그러나 KoreaMed MeSH 체크태그를 기준으로 했을 경우 MEDLINE MeSH 체크태그와의 일치율은 84.24%에 달했다. 일치율은 종별이 가장 높았고, 동물명, 성별, 연령그룹순이었다. 연령그룹에 대하여 초록내 패턴을 발견하여 반자동색인 필터로 적용한다면 일치율을 높일 수 있다. 궁극적으로는 연구의 핵심적인 연구대상이나 재료를 특정적이고 구체적인 단어 혹은 MeSH로 표현하는 초록 작성 기술이 요청된다.

본 연구에서는 PubMed에 등재되었으나 Medical Subject Headings(MeSH)가 부여되지 않은 국내 의학학술지의 문헌을 대상으로 미국국립의학도서관 (NLM: National Library of Medicine)의 Medical Text Indexer(MTI)를 활용하여 MeSH 용어를 추천받은 후, PubMed 레코드의 유사주제문헌 (Relation Citations, PRC)에 부여된 MeSH와의 일치여부를 분석하였다. 또한 논문의 저자가 부여한 키워드(저자키워드)와 PRC MeSH의 일치여부도 비교하였다. PRC MeSH와 MTI MeSH 추천어의 일치율은 주표목이 21.1%였고, 체크태그는 18.1%, 부표목은 16.5%로 나타났다. 우리나라 의학논문에 나타난 저자키워드의 중요한 특징은 MeSH 주표목 위주이고, 체크태그와 부표목은 거의 사용하지 않는 것이다. 따라서 저자키워드와 PRC MeSH 주표목과의 일치율은 23.4%에 이르지만, 체크태그와 부표목의 일치율은 각각 1%, 2.1%였다. 색인전문가가 통제어휘를 사용하여 색인하는 과정에서 PRC와 MTI의 MeSH 주표목과 저자키워드가 일치하는 용어를 주표목으로 부여하고, PRC와 MTI가 추천하는 체크태그와 부표목을 활용하는 등 국내 의학문헌의 MeSH 용어 부여 작업을 반자동화(semi-indexing)하면, 정확하고 신속한 MeSH 부여 작업이 가능할 것이다.

The medical thesaurus, MeSH (Medical Subject Heading), has been used as a controlled vocabulary thesaurus for English medical paper indexing for a long time. In this paper, we propose an automatic cross language keyword assignment method, which assigns English MeSH index terms to the abstract of a Korean medical paper. We compare the performance with the indexing performance of human indexers and the authors. The procedure of index term assignment is that first extracting Korean MeSH terms from text, changing these terms into the corresponding English MeSH terms, and calculating the importance of the terms to find the highest rank terms as the keywords. For the process, an effective method to solve spacing variants problem is proposed. Experiment showed that the method solved the spacing variant problem and reduced the thesaurus space by about 42%. And the experiment also showed that the performance of automatic keyword assignment is much less than that of human indexers but is as good as that of authors.

Purpose: The purpose of this study was to analyze how accurately authors of the Journal of Korean Academy of Fundamentals of Nursing used MeSH terms as key words. Method: A total of 724 key words used in the 225 papers of Journal of Korean Academy of Fundamentals of Nursing from 2003 to 2007 were compared with MeSH terms. Results: Fifty nine point eight percent of total key words were completely coincident with MeSH terms, 13.5% were entry terms, and 21.8% were not MeSH terms. The coincidence rates for 2003 and 2007 separately were 38.5% and 70.9%. Also, 25.3% of papers precisely used MeSH terms as key words and 8% did not use any MeSH terms. Conclusion: The results show that the coincidence rate of key words with MeSH terms was at a moderate level and gradually increased according to year. However, there is a need for us to understand MeSH more specifically and accurately.

Purpose: The purpose of this study is to compare and analyze keywords of articles in the Korean Ophthalmic Optics Society to MeSH (Medical Subject Headings) terms. The study hopes to enhance the understanding and usage of MeSH and give fundamental information to the Korean Ophthalmic Optics Society in advance. Methods: A total of 1952 keywords from 409 informative articles published from 2004, Vol 9(1) to 2016, Vol 21(1) were compared with MeSH terms according to the criteria of complete coincidence, incomplete coincidence and complete incoincidence. Results: 439 keywords (22.4%) were completely coincident with MeSH terms, 815 keywords (41.8%) were incompletely coincident with MeSH terms and 693 keywords (35.5%) were completely incoincident with MeSH terms. The most used keyword in MeSH terms is in the order of Myopia, Astigmatism and visual acuity. For the incompletely coincident keywords Refractive error, Soft contact lens, and Phoria were used the most. Finally, the most used keywords in the category of completely incoincident were Accommodative lag and Pseudomonas aeruginosa. Conclusions: It is highly recommended that MeSH terms are selected as controlled keywords to increase usage of searced Korean Ophthalmic Optics Society articles in MEDLINE.

In order to analyze how accurately authors of Korean medical papers use MeSH terms, the key words of Korean medical papers assigned by authors (author terms) are compared with the MeSH terms listed in the corresponding MEDLINE records. A total of 1,826 author terms were used in the 415 Korean Journal of Parasitology papers published between 1989 and 1998. An average of 4.4. author terms and 9.9 MeSH terms were assigned to each paper. 35.5% of author terms matched exactly or partially with MeSH terms, the average being 1.6 terms per paper. The exact match terms consisted only 10.1%. The result of this study shows that the major difference between author terms and MeSH terms are in the use of subheadings and check tags. It indicates that the Korean authors in general do not have sufficient knowledge in selecting and using MeSH terms.

Purpose : We try to disclose how much the keywords of the papers from the Korean Journal of Emergency Medical Services with Medical Subject Headings(MeSH) terminologies and to understand the major subjects of the recent emergency medical technology research in Korea from keywords. Methods : We analyzed keywords from 524 articles of the Korean Journal of Emergency Medical Services that were published between 2005 and 2011. We investigated frequently used keywords and what percentages of keywords agree with MeSH terms using the MeSH browser. Results : There were on average 3.2 keywords per article. The most frequent key words were AED, Attitude, Cardiopulmonary Resuscitation, CPR, EMT, EMT students, External Defibrillator, Job satisfaction, Knowledge, 119 EMT in order. The number of terms in precise agreement with MeSH headings was 101(19.3%); 327 terms(62.4%) were not found in the MeSH browser and 96 terms(18.3%) partially matched MeSH terms. Conclusion : Many keywords used in the Korean Journal of Emergency Medical Services did not agree with MeSH terms. We conclude that contribution rules should be using MeSH terms and authors should be educated in the proper use of MeSH terms in their research and subsequent publication.

Medical Subject Headings (MeSH), a medical thesaurus created by the National Library of Medicine (NLM), is a useful resource for natural language processing (NLP). In this article, the current status of the Japanese version of Medical Subject Headings (MeSH) is reviewed. Online investigation found that Japanese-English dictionaries, which assign MeSH information to applicable terms, but use them for NLP, were found to be difficult to access, due to license restrictions. Here, we investigate an open-source Japanese-English glossary as an alternative method for assigning MeSH IDs to Japanese terms, to obtain preliminary data for NLP proof-of-concept.

The findings from this study are summarized as follows: 1. Hangul 2004 has 16,023 Chinese Character codes. Among them, 15,231 Chinese Character codes are searched by DB, the others are unsearchable codes. 2. Among 15,231 Chinese Character codes of Hangul 2004, 2,471 Chinese Character codes are converted into 2,232 Simplified Chinese Character codes by Traditional and Simplified Chinese Character Converting program in Hangul 2004. 3. The 5th edition TCM-MeSH has 6,385 thesauruses and 2,142 kinds of Chinese Characters. 4. If we use Simplified Chinese Character of Hangul 2004 to search for TCM-MeSH, we will find 94.3% of TCM-MeSH. But If we use Traditional Chinese Character of Hangul 2004 to search for TCM-MeSH, we will find only 34.2% of TCM-MeSH.

The purpose of this study is to analyze the equality between keywords used in the Journal of the Korean Academy of Pediatric Dentistry and medical subject headings (MeSH). A total of 4,353 English keywords in 1,165 papers from 1998 to 2014 were eligible for this study. We classified them according to equality to MeSH. We assayed patterns of errors in using MeSH, and reviewed frequently used non-MeSH terms. 24.9% of total keywords were completely coincident with MeSH terms, 75.1% were not MeSH terms. The results show that the accordance rate of keywords with MeSH terms in the Journal of the Korean Pediatric Dentistry is at a low level. Therefore, there is a need for authors to understand MeSH more specifically and accurately. Use of proper keywords aligned with the international standards such as MeSH is important to be properly cited. Authors should pay attention and be educated on the correct use of MeSH as keywords.
