ABSTRACT SNOMED CT is a standard clinical terminology to provide a standardized way to record and manage clinical records for EMR or EHR. The structure of SNOMED CT is very complex because of huge expressive power and its internal design mechanism. Although there are some SNOMED CT browsers for browsing and searching SNOMED CT concepts, they are less effective because they do not consider such complexity of SNOMED CT. This paper depicts problems of current SNOMED CT browsers and analyze SNOMED CT dataset. Then, this paper analyze requirements of SNOMED CT browser which improves searching and selecting of appropriate clinical terms. ํ‚ค์›Œ๋“œ : SNOMED CT, ์˜ํ•™์šฉ์–ด, ๊ฒ€์ƒ‰๋ธŒ๋ผ์šฐ์ €, ์š”๊ตฌ๋ถ„์„ Key word : SNOMED CT, Clinical Terms, Search Browser, Requirement Analysis ์ ‘์ˆ˜์ผ์ž : 2014. 10. 01 ์‹ฌ์‚ฌ์™„๋ฃŒ์ผ์ž : 2014. 10. 31 ๊ฒŒ์žฌํ™•์ •์ผ์ž : 2014. 11. 05 * Corresponding Author Wooseok Ryu (E-mail:wsryu@cup.ac.kr, Tel:+82-51-510-0611) Department of Health Care Management, Catholic University of Pusan, Busan, 609-757, Korea Open Access http://dx.doi.org/10.6109/jkiice.2014.18.11.2691 print ISSN: 2234-4772 online ISSN: 2288-4165 This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License(http://creativecommons.org/li-censes/ by-nc/3.0/) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.
