This study examined the method for adding related to "stomach neoplasms" as filters to the Medical Subject Headings (MeSH) for search as well as a method for improving the search efficiency through a word-proximity search by measuring the distance of co-occurring terms. A total of 8,625 articles published between 2007 and 2016 with the major topic terms "stomach neoplasms" were downloaded from PubMed article titles. The vocabulary to be added to the MeSH for search were analyzed. The search efficiency was verified by 277 articles that had "Stomach Neoplasms" indexed as MEDLINE MeSH in KoreaMed. As a result, 973 terms were selected as the candidate vocabulary. "Gastric Cancer" (2,780 appearances) was the most frequent term and 7,376 compound words (88.51%) combined the histological terms of "stomach" and "neoplasm", such as "gastric adenocarcinoma" and "gastric MALT lymphoma". A total of 5,234 compounds words (70.95%), in which the co-occurring distance was two words, were found. The matching rate through the MEDLINE MeSH and KoreaMed MeSH Indexer was 209 articles (75.5%). The search efficiency improved to 263 articles (94.9%) when the search filters were added, and to 268 articles (96.7%) when the 13 word-proximity search technique of the co-occurring terms was applied. This study showed that the use of a thesaurus as a means of improving the search efficiency in a natural language search could maintain the advantages of controlled vocabulary. The search accuracy can be improved using the word-proximity search instead of a Boolean search.

This study evaluated the applicability of the static hierarchic clustering model to clustering query results in OPAC. Two clustering methods(Between Average Linkage(BAL) and Complete Linkage(CL)) and two similarity coefficients(Dice and Jaccard) were tested on the query results retrieved from 16 title-based keyword searchings. The precision of optimal dusters was improved more than 100% compared with title-word searching. There was no difference between similarity coefficients but clustering methods in optimal cluster effectiveness. CL method is better in precision ratio but BAL is better in recall ratio at the optimal top-level and bottom-level clusters. However the differences are not significant except higher recall ratio of BAL at the top-level duster. Small number of clusters and long chain of hierarchy for optimal cluster resulted from BAL could not be desirable and efficient.

The purpose of this study was to propose the improvements for high quality of National Library of Korea (NLK) Subject Headings List which was developed as a subject access tool in 2002. For this study, literature review, case study for subject headings lists of national libraries, and data analysis of headings and relationships were performed. Several problems were found as follows: inconsistency of subject headings descriptions, unclear and unnecessary relationships among headings, inconsistency of hierarchical relationships, lack of currency, incorrectness of classification numbers, duplication of newly requested terms, and assignment of non-preferred and unregistered terms in bibliographic records. Focusing on these problems, modifications of subject headings and bibliographic records, installation and operation of an review committee on subject headings, and supplementation of a manual were suggested to improve NLK Subject Headings List.

We propose a method to search for similar images by using outline lines and viewpoints. In the first test, the three-dimensional image, which can't control the motion, has lower search accuracy than the static flat image. For the cause analysis, six specific tropical fish data were selected. We made a 3D graphics of tropical fishes of each kind, and we made 144 image outline lines with 12 stage viewpoints of top, bottom, left and right. Tropical fish by type were collected and sorted by time of search through similar search. Studies have shown that there are many unique viewpoints for each species of tropical fish. To increase the accuracy of the search, a User Interface was created to select the user's point of view. When the user selects the viewpoint of the image, a method of showing the result in consideration of the range of the related viewpoint is proposed.

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.

Although traditional printed materials m indexed and abstracted by human beings with tools like thesaurus or controlled vocabulary, information resources on World Wide Web(WWW) are automatically indexed and abstracted without human beings efforts. It would be useful to investigate what major differences are in processes and in elements of indexing and abstracting between traditional printed materials and information resources on WWW. After discussing how WWW search engines work, six major WWW search engines were chosen for this study. Then, 17 indexing elements, 11 abstracting elements, and 2 meta elements were examined. Overall trends and issues for the future development of indexing and abstracting on WWW are also discussed.

현재 서비스 산업에서는 급변하는 고객의 욕구를 맞추기 위해 기업 간의 서비스 경쟁 심화 및 다양한 각도에서의 최상의 고객서비스를 제공하기 위한 노력이 지속적으로 시도되고 있다. 서비스 종사자들도 기업과 고객이 기대하는 고객 중심 서비스 제공에 기여하고 있다. 과도한 서비스 제공은 서비스 종사자의 감정적 스트레스 등과 같은 부작용을 발생시키고 있는데, 기업과 고객과의 접촉 채널로서의 중요한 역할에 임하는 콜센터 상담사들의 스트레스 해소는 업무 향상에 있어서 필요하다. 스트레스 해소를 위한 정신적인 긍정어 즉, 역경을 이겨내는 긍정의 힘이 '회복탄력성'으로서, 콜센터 상담사의 회복탄력성을 분석한 결과 근무경력과 업무 유형에 따라 차이를 보였다. 회복탄력성의 구성요소 중 감정통제력, 충동통제력, 원인분석력, 공감능력, 자기효능감은 근무경력에 따라 차이를 보였고, 낙관성, 공감능력은 업무 유형에 따라 차이가 나타났다.

Different users or the same user using controlled versus free-text vocabularies could generate different queries for the same information need. It has been known in the information retrieval literature that different query representations may retrieve different sets of documents. In this paper, we first generate multiple query vectors from a given information problem by using different relevance feedback methods. Then, we combine the multiple query vectors into a single query vector. We also show through experiments that significant improvements can be achieved by the combination of the multiple query vectors.

중등 지구과학교과서와 대학 교재에서 학습하는 광물과 암석 이름은 대부분 영어, 한자, 일본어에서 도입한 용어이다. 이 용어에 대한 어원과 말뜻에 대한 분석이나 연구가 되지 않은 상태에서 바로 사용해왔기 때문에 지질학 초보자들이 학습하기에 아주 어렵다. 광물과 암석이름의 어원과 말뜻을 잘 알지 못하고 단순히 외우거나 학술적인 이름이나 의미만을 생각하고 사용하고 있으며, 한 광물이나 암석에 대하여 여러 가지 이름을 사용하기도 한다. 심지어 전혀 엉뚱한 암석 이름이 대중 사이에서 사용되고 있지만 이를 통제하지도 못하고 그 명칭이 틀렸다는 것도 모르고 있다. 예를 들면 영어로 Shale을 중등 교과서와 대학 교재에서 영어 발음을 따라 한국어로 셰일이라고 표기하지만 중국과 일본에서는 혈암(頁岩)으로 표기한다. 우리나라의 대중 매체의 인터넷 사전과 대중들이 사용하는 용어는 중국어 혈암(頁岩)을 공공연하게 '혈암'으로 표기하고 있다. '혈(頁)'을 한자 사전에서 찾아보면 '머리 혈'과 '책 면 엽'으로 정리되어 있다. 그러면 셰일의 암석학적 특징으로 볼 때 혈암이라고 해야 하나? 엽암이라고 해야 하나? 과학과의 다른 분야에서는 어려운 한자를 쉬운 한글로 표준화하는 연구와 실행을 꾸준히 진행해오고 있다. 생물의 경우 생물의 어려운 학명을 이미 쉬운 한글로 표준화했으며, 그 학명이 학생과 대중들에게 널리 알려져 있다. 지구과학의 교과서 문장에 나오는 단어와 전문용어가 한자를 한글로 표기한 경우가 많은데 이 단어들을 하루 속히 한글로 표준화하여 전문가들이 먼저 사용하는 동시에 학생과 대중들에게 알려 주어야 한다. 이렇게 되면 지구과학의 내용보다 용어가 어렵다는 인식을 바꾸어 줄 것이고 지구과학을 전공하고자 하는 학생들에게 희망과 용기를 줄 것이다. 그 일환으로 광물과 암석 이름의 어원을 조사해 보고 한글 표준화의 가능성을 타진해 보고자 한다.

In order to index documents, a thesaurus which consists of terms and relationships between terms is used. When an index term is selected, retrieval performance in the information retrieval system could be improved by using the relationship between the terms in the thesaurus. Recently, the usage of a thesaurus are extended from information retrieval to language and knowledge engineering, but term relationships in a thesaurus are simply represented in equivalence, hierarchy, and association. Particularly the associative relationship is vague in its definition and range as compared with the other relationships, i.e. equivalence, hierarchy, therefore the terms that are selected through associative relationship aren't well controlled. This study examines the relationships of existing thesauri, especially the types and ranges of associative relationship, and suggests the adequate type of associative relationship.
