  • 본 논문은 분산, 독립적인 다수의 문서 컬렉션으로부터의 검색결과를 병합하는 컬렉션 융합(collection fusion)문제에 대한 효과적인 랭킹방법을 제시한다. 일반적인 컬렉션 융합 문제란 분산되어 있는 다수의 문서 컬렉션에서 독립적이고 능동적인 검색기들의 검색결과를 효과적으로 랭킹(ranking) 병합하는 것인데, 각기 다른 특성을 가진 다수의 컬렉션을 동일한 검색기를 통하여 검색된 결과를 병합하는 환경과 서로 다른 알고리즘을 갖는 검색기를 통한 검색 결과 병합 환경으로 나누어 질 수 있다. 본 논문에서는 서로 다른 특성을 갖는 다수의 컬렉션을 서로 다른 알고리즘을 갖는 검색기들을 통하여 검색한 결과를 병합하는 방법을 제시한다. 각 컬렉션에 학습 질를 넣어 얻은 정보를 토대로, 실제 질의를 넣었을 때 각각의 컬렉션에서 나온 결과가 통합 결과 집합에서 차지하는 비율과 각 문서의 순위를 결정한다. 기존 연구에서 사용한 방법들은 랜덤성에 의존한 비결정적인 랭킹 방법을 제시하거나, 단순하게 검색결과 집합의 문서 수를 바탕으로 인터리빙(interleaving)하는 방법을 제시하였다. 본 논문에서는 학습 질의에서 나온 정보를 기반으로 결정적이면서도 보다 효과적인 랭킹 방법을 제시한다.

  • The exponential growth of information on the web far exceeds the capacity of present day information retrieval systems and search engines, making information integration on the web difficult. In order to overcome this, semantic web technologies were proposed by the World Wide Web Consortium (W3C) to achieve a higher degree of automation and precision in information retrieval systems. Semantic web, with its promise to deliver machine understanding to the traditional web, has attracted a significant amount of research from academia as well as from industries. Semantic web is an extension of the current web in which data can be shared and reused across the internet. RDF and ontology are two essential components of the semantic web architecture which support a common framework for data storage and representation of data semantics, respectively. Ontologies being the backbone of semantic web applications, it is more relevant to study various approaches in their application, usage, and integration into web services. In this article, an effort has been made to review the research work being undertaken in the area of design and development of ontology supported information systems. This paper also briefly explains the emerging semantic web technologies and standards.

  • Most recent web search engines perform effective keyword-based multimedia contents retrieval by investigating keywords associated with multimedia contents on the Web and comparing them with query keywords. On the other hand, most music and compilation albums provide professional artwork as cover art that will be displayed when the music is played. If the cover art is not available, then the music player just displays some dummy or random images, but this has been a source of dissatisfaction. In this paper, in order to automatically create cover art that is matched with music contents, we propose a music album cover art creation scheme based on music contents analysis and result synthesis. We first (i) analyze music contents and their lyrics and extract representative keywords, (ii) expand the keywords using WordNet and generate various queries, (iii) retrieve related images from the Web using those queries, and finally (iv) synthesize them according to the user preference for album cover art. To show the effectiveness of our scheme, we developed a prototype system and reported some results.

  • Objectives : To review to determine difference in the effect of age, gender, location of electrode, test meal and period of recording that influence Electrogastrography (EGG) parameters and to study its oriental medical application. Methods : We investigate the research results through internet search engines, Pub Med, Karger, Mary Ann Libert and Pro Quest. Results : Age and gender influence postprandial Dominant Frequency Instability Coefficient (DFIC). Body mass index (BMI) influence fasting and postprandial EGG parameters. Menstrual cycle phase influence fasting Dominant Frequency (DF). Test meal volume and composition influence postprandial EGG parameters. But reduced-calorie test meal have no effect on EGG parameters. Conclusions : Because the amplitude of surface-recorded SW(slow wave) is very weak, EGG is influenced by many factors. Age, gender, BMI, menstrual cycle phase, test meal volume and test meal composition influence EGG parameters. but reduced-calorie test meal have no effect on EGG parameters.

  • Purpose: This study was to analyze the characteristics and effect size of intervention studies applied to cancer-related fatigue in Korea. Methods: For meta-analysis, a total of 963 studies were retrieved from search engines. And 19 studies with a total of 721 participants published from 1990 to 2010 were selected upon their satisfaction with the inclusion criteria. Two authors independently extracted data from the selected studies and assessed the methodological quality. The data was analyzed by the RevMan 5.0 program of Cochrane library. Results: Intervention studies included 4 studies on foot-reflexo-massage (21.1%), comprehensive program (21.1%), and exercise (21.1%), respectively, 3 for hand-reflexo-massage (15.8%), and 4 for others. The effect size of the intervention studies shown higher effect size in order of exercise (d=-1.80), and foot & hand-reflexo-massage (d=-0.55). Conclusion: This study suggest that exercise can reduce the intensity of cancer-related fatigue, even though the number of intervention studies and randomized controlled trials were very few. There is limited evidence that reflexo-massage is effective in reducing cancer-related fatigue.

  • Purpose: This study reviewed the common conditions associated with displacement of inferior alveolar nerve canal. Materials and Methods: General search engines and specialized databases including Google Scholar, Pub Med, Pub Med Central, Science Direct, and Scopus were used to find relevant studies by using keywords such as "mandibular canal", "alveolar canal", "inferior alveolar nerve canal", "inferior dental canal", "inferior mandibular canal" and "displacement". Results: About 120 articles were found, of which approximately 70 were broadly relevant to the topic. We ultimately included 37 articles that were closely related to the topic of interest. When the data were compiled, the following 8 lesions were found to have a relationship with displacement of mandibular canal: radicular/residual cysts, dentigerous cyst, odontogenic keratocyst, aneurysmal bone cyst, ameloblastoma, central giant cell granuloma, fibrous dysplasis, and cementossifying fibroma. Conclusion: When clinicians encounter a lesion associated with displaced mandibular canal, they should first consider these entities in the differential diagnosis. This review would help dentists make more accurate diagnoses and develop better treatment plans according to patients' radiographs.
