  • A topic segmentation module is to divide statements or conversations into certain topic units. Until now, topic segmentation has progressed in the direction of finding an optimized set of segments for a whole document, considering it all together. However, some applications need topic segmentation for a part of document which is not finished yet. In this paper, we propose a model to perform topic segmentation during the progress of the statement with a supervised learning model that uses a convolution neural network. In order to show the effectiveness of our model, we perform experiments of topic segmentation both on-line status and off-line status using C99 algorithm. We can see that our model achieves 17.8 and 11.95 of Pk score, respectively.

  • Objectives: This study was for analyzing the research about international marriage immigrant women and a trial to find the right direction for future research. Methods: Sixty articles published from June, 2004 to June, 2009 were reviewed and analyzed according to the general characteristics, major of author, and theme of health domains. Results: Most of them were master's thesis(71.7%) and journals(21.7%) and doctoral dissertation(6.7%) have been published mostly after thesis. Among 83.3% for quantitative research, descriptive(33.3%) and descriptive correlation(41.7%) methods were the most used and there were some qualitative researches(16.7%). The most frequently used data gathering method was questionnaire(81.7%) and the next was interview(16.7%). The major rates of the author were 61.7% for social welfare and 2.1% for nursing. The investigated variables in social health domain were adaptation(28.3%), and communication(1.7%). In psychological health domain, marriage satisfaction(16.7%), life satisfaction(11.7%), and depression(10.0%) were most researched. Utilization of medical center(5.0%) and health promotion behavior(1.7%) were investigated in physical health domain. Conclusions: Above this, most articles were researched about the adaptation of international marriage immigrant women. But the life in foreign countries can cause physical and psychosocial unhealthy conditions, so many-sided health related researches are supposed to be conducted for adaptation and prevention health problems of international marriage immigrant women.

  • This paper proposes an extraction method which extracts two different thematic maps, which have different line thickness from each other in a raster image that contains the two thematic maps. In the proposed method, the depth of each pixel is calculated according to the amount of pixels in its surrounding neighborhood, and then the thinning is performed. By using depth threshold, two thematic maps are first extracted from the thinning result. There are noise images and skeleton disconnection in the lines of each extracted thematic map. Each thematic map extraction is finally completed after removing the noise images and connecting the disconnected lines. Through the experiment, we showed that the proposed method could be used for the extraction of each thematic map of a raster image which included two thematic maps.

  • The construction of ontology defines as complicated semantic relations needs precise and expert skills. For the well defined ontology in real applications, plenty of information of instances for ontology classes is very critical. In this study, crawling algorithm which extracts the fittest topic from the Web overflowing over by a great number of documents has been focused and developed. Proposed crawling algorithm made a progress to gather documents at high speed by extracting topic-specific Link using URL patterns. And topic fitness of Link block text has been represented by fuzzy sets which will improve a precision of the focused crawler.

  • Purpose: Health technology research & development is an important area to leading future. This study examined the current trends for 'oncogene' based on the research subject network to deduce a research front. Method: Papers were extracted from PubMed database using MeSH term for studies on 'oncogenes' and further categorized as papers published by Korean. Keywords were collected from all of articles. Research subject network was generated by keywords. Research subject network was analyzed by weighted degree centrality based social network analysis and transition of research subjects was analyzed by the time series. Results: On 'oncogenes', 'Genes, ras', 'Apoptosis', 'Signal Transduction' had a high degree centrality and currently 'Antineoplastic Agents', 'Prognosis', and 'Tumor Markers, Biological' were widely conducted. Conclusion: Consistency of research trend pattern was found by analyzing oncogene network with compromised to international vs. domestic trends. Analyzing keyword networks in various subject area, those will allow us to predict the research progress and propose evidence of research & developmental strategy.

  • 본 논문에서는 텍스트 문서의 주제어를 추출하고 문서를 주제별로 분류하기 위해 확률적 그래프 모델을 사용하는 방법을 제안하였다. 텍스트 문서 데이터를 문서와 단어의 쌍으로(dyadic)표현하여 확률적 생성 모델을 학습하였다. 확률적 그래프 모델의 학습에는 정의된 likelihood를 최대화하기 위한 EM(Expected Maximization)알고리즘을 사용하였다. TREC-8 AdHoc 텍스트 에이터에 대하여 학습된 확률 그래프 모델의 성능을 실험적으로 평가하였다. 이로부터 찾아 낸 문서에 대한 주제어가 사람이 제시한 주제어와 유사한 지와, 사람이 각 주제에 대해 분류한 문서가 이 확률모델로부터의 분류와 유사한 지를 실험적으로 검토하였다.

  • 본 논문은 웹 문서가 특정 주제와 관련된 정보를 담고 있는지를 특정 주제의 단어와 다른 주제의 단어들 사이의 관계를 이용해 평가할 수 있는 방법을 제시하고자 한다. 특정 주제와 관련된 웹 문서에 단어$_{A}$와 단어$_{B}$가 그렇지 않은 웹 문서보다 나온 수가 더 많다면, 단어$_{A}$와 단어$_{B}$의 연결 관계는 특정 주제에 대해 Positive하다고 볼 수 있다. 반대의 경우에는 Negative하다고 볼 수 있다. 이러한 단어와 단어의 연결 관계를 수치화하여 특정 주제와 관련된 웹 문서의 평가에 사용할 수 있도록 WordNet과 BFN을 이용해 보고자 한다.
