Abstract

The purpose of this study is to find out whether image similarity between celebrities and brands on social network service be a determinant to predict advertising effectiveness. To this end, an advertising effect prediction model for celebrity endorsed advertising was created and its validity was verified through a machine learning method which is a big data analysis technique. Firstly, the celebrity-brand image similarity, which was used as an independent variable, was quantified by the association network theory with social big data, and secondly a multiple regression model which used data representing advertising effects as a dependent variable was repeatedly conducted to generate an advertising effect prediction model. The accuracy of the prediction model was decided by comparing the prediction results with the survey outcomes. As for a result, it was proved that the validity of the predictive modeling of advertising effects was secured since the classification accuracy of 75%, which is a criterion for judging validity, was shown. This study suggested a new methodological alternative and direction for big data-based modeling research through celebrity-brand image similarity structure based on social network theory, and effect prediction modeling by machine learning.

본 연구는 소셜 빅데이터에 기반을 둔 유명인과 브랜드의 이미지 유사도가 광고효과를 예측할 수 있는 결정변수가 될 수 있는지를 파악하기 위해, 광고효과 예측모형을 생성하고 빅데이터 분석기법인 기계학습 방법을 통해 그 타당도를 검증하는 것을 목적으로 하였다. 이를 위해 SNS상의 키워드 네트워크 구조에 기반하여 유명인-브랜드 이미지 유사도를 정량화하고, 학습 데이터를 통해 이미지 유사도를 독립변수로, 광고효과 데이터를 종속변수로 하는 다중회귀모형을 반복 실시하여 광고효과 예측모형을 생성하였다. 이렇게 생성된 예측모형의 정확도를 판단하기 위해 예측 데이터에서 얻은 광고효과 예측값과 비교 기준으로서의 서베이값을 비교한 결과, 타당도를 판단하는 기준치인 75%의 분류 정확도를 보였으므로 본 광고효과 예측 모델링의 타당성은 확보된 것으로 입증되었다. 본 연구는 유명인-브랜드 이미지 유사성 구조를 소셜 네트워크 구조로 설명하고 그 효과를 기계학습을 통한 예측 모델링으로 검증하여 빅데이터 기반 모델링 연구에 새로운 방법론적 대안과 방향을 제시하였다.
