  • 19대 총선에서 특정 후보를 홍보하기 위한 목적으로 개인 맞춤형 위치기반소셜네트워크서비스(LBSNS, Location Based Social Network Service) 앱(App)을 기획하여 개발하고 선거기간 동안 활용함으로써 선거 전후 해당 후보의 지지율 변화에 어느 정도 기여했는지 그 영향을 분석하였다. 대전광역시 6개 지역구 24명의 후보를 대상으로 개인 맞춤형 LBSNS 앱을 활용한 후보와 그렇지 않은 후보를 구분하여 선거운동 기간 동안 언론에 공개적으로 발표된 지지율과 개표 결과를 바탕으로 개인별 지지율 변화를 비교하였다. 해당 앱을 활용한 3명의 후보는 각각 12.6%, 11.4% 및 11.2%씩 두 자리 수의 지지율 상승이 있었지만 나머지 21명의 후보들은 지지율 변화는 모두 3% 이내로 머물러 개인맞춤형 스마트폰 앱을 활용함으로써 후보 지지율 상승에 상당한 효과가 있었음이 밝혀졌다.

  • During 19th general election the customized LBSNS(Location Based SNS) application for some candidates of the National Assembly planned and developed based on the object identification, ePosition, comprising the candidate's name have been applied for an election campaign. The approval rating change before and after 19th election campaign period for each candidate was quantitatively studied how it would be affected by the candidate custom LBSNS application. Only 3 out of 24 candidates in 6 local electorates in the Daejon Metropolitan City have adopted the customized LBSNS application and the rest 21 candidates have not, whose approval rating change before and after an election campaign has been analyzed comparatively candidate by candidate. The approval rating for 3 candidates adopting LBSNS application went up by 12.6%, 11.4%, 11.2% respectively, but those for the rest 21 candidates all changed within 3%.

  • We compared and analyzed the relationship between vote intention, vote expectation, and party approval rate using the 19th Presidential Election and the 7th Nationwide Simultaneous Local Election (Regional Local Government Election) poll data. The case study provides an alternative method of predicting the winner using vote expectation and a party approval rate that can improve the accuracy of election forecasting.

  • 현재 인터넷 공간은 사람들의 관심사나 사회적인 이슈들을 반영하고 있다. 사회적으로 어떤 사건이 발생하면 그 사건에 관한 뉴스 기사나 관련된 다양한 콘텐츠들이 생성되어 여러 사람들에게 소비되고 공유된다. 뿐만 아니라 이와는 반대로 인터넷 공간에서 사람들에게 많은 관심을 받거나 이슈가 된 사건이 사회적인 관심거리가 되기도 한다. 최근에는 인터넷 공간에서 발생하는 정보 검색이나 콘텐츠 생성 패턴을 분석하여 실제 사회에서의 이슈나 트렌드를 예측하려는 연구가 활발히 진행되고 있다. 이 논문에서는 인터넷을 기반으로 분석한 자료와 전문 기관에서 분석한 자료의 상관관계를 분석하고자 한다. 그 중 최근 뉴스나 콘텐츠가 많이 생산되는 2012년 대통령 선거 후보에 관한 인터넷 뉴스 기사량과 전문조사 기관에서 발표한 각 후보의 지지율을 보이고 두 자료 간의 상관관계를 분석한다. 그리고 실험 결과로 대선 후보들의 기사 점유율과 발표된 지지율에 높은 상관관계가 있음을 보인다.

  • For 2007 Korea presidential election, most polls by telephone surveys indicated Lee Myung-Bak led the second runner-up Jung Dong-Young by certain margin. The margin between two candidates can be estimated accurately by averaging individual poll results, provided there exists no systematic bias in telephone surveys. Most Korean telephone surveys via telephone directory are based on quota samples, with the region, the gender and the age-band as quota variables. Thus the surveys may result in certain systematic bias due to unbalanced factors inherent in quota sampling. The aim of this study is to answer the following questions by the analytic methods adopted in Huh et al. (2004): Question 1. Wasn't there systematic bias in estimates of support rates. Question 2. If yes, what was the source of the bias? To answer the questions, we collected eighteen surveys administered during the election campaign period and applied the iterated proportional weighting (the rim weighting) to the last eleven surveys to obtain the balance in five factors - region, gender, age, occupation and education level. We found that the support rate of Lee Myung-Bak was over-estimated consistently by 1.4%P and that of Jung Dong-Young was underestimated by 0.6%P, resulting in the over-estimation of the margin by 2.0%P. By investigating the Lee Myung-Bak bias with logistic regression models, we conclude that it originated from the under-representation of less educated class and/or the over-representation of house wives in telephone samples.

  • Survey reports of election opinions consist of numerous cross-tabulations between socio-demographic variables and political opinions including preferred candidates. Since socio-demographic variables are related each other, duplicate interpretations arise. The aim of this study is twofold: The first is to separate the effects of socio variables such as education, occupation and income from the effects of demographic variables such as region, sex and age. The second is the visualization of multiple cross-tabulations in low-dimensional space by extended doubling technique of correspondence analysis. Survey researchers may get some help from this study to present their survey results more lucidly and visually.

  • The 2018 midterm elections were considered a referendum for Trump Presidency, especially because Latino community has been feeling that the anti-immigration, anti-Latino policies of Trump administration are harmful to the community. News Media and pundits predicted the boost of the Latino turnout and its positive effects on Democratic candidates at all levels. The purpose of this paper is to provide an overview of Latino demographics and Latino public opinion and to analyze the election results with exit poll data and actual aggregate data. The data analysis shows that, compared to 2014 midterm elections, Latino turnout and the support for Democratic candidates actually increased in most counties and precincts, which is more salient in the areas with heavy Latino concentration.

  • It is very important to obtain objective and credible information through election polls in order to contribute to the correct voting behavior of the voters or to establish appropriate election strategies for candidates or political parties. Therefore, many related organizations such as political parties, media organizations, and research institutions have been making efforts to improve the accuracy of the results of the polls and the election prediction. Kim et al. (2017) analyzed whether the non-response group responded that there is no support candidate in the election survey to increase the accuracy of the estimation of the vote rate. As a result, it has been confirmed that the accuracy of the estimation of the vote rate can be significantly improved by performing an appropriate classification on the non-response layer. In this study, we propose a method to estimate the turnout by each strata (sex, age group) under the condition that the total turnout rate is given for a specific district (region) and propose a procedure to predict the vote rate by reflecting the turnout. In addition, case studies were conducted using data gathered through telephone interviews for the 20th National Assembly elections in 2016.

  • The existing system consumes a considerable amount time and cost for extracting the patterns from whole sequences or misaligned sequences. In this paper, We propose the classification system, which creates the partition sequence sections using multiple sequence alignment method and extracts the sequential patterns from these section. These extracted patterns are accumulated motif candidate sets and then used the training sets of SVM classifier. This proposed system predicts a HPV-type(high/low) using the learned knowledges from known/unknown protein sequences and shows more improved precision, recall than previous system in 30% minimum support.

  • Local governments within the boundaries of a state need increasing flexibility to satisfy diverse economic, social, and environmental goals in their particular geographical setting. However, many candidates in the local election in South Korea tend to see local politics as an extension of national-level politics. In particular, this paper mainly deals with how the voters' evaluation of a president's performance has influenced subnational elections in South Korea. Our analysis suggests that the fate of candidates in subnational elections is shaped by the performance of the incumbent president in both economic development and foreign affairs.
