초록

개인화 추천시스템은 각 개인의 관심사나 선호도를 분석하여 이에 맞는 정보나 제품을 추천해주는 것을 의미한다. 이러한 개인화 추천을 통해 소비자들은 본인에게 필요한 제품들을 보다 빠르게 접함으로써 정보 탐색에 소모하는 시간을 단축할 수 있으며, 기업들은 소비자들의 필요에 맞는 적절한 제품을 추천해줌으로써 기업 이윤을 증가시킬 수 있다. 본 연구에서는 대표적인 개인화 추천 기법들인 협업 필터링, 행렬 요인화, 딥러닝을 사용하여 소비자에게 제품을 추천해준다. 이를 위해 원데이터 (Raw data)인 쇼핑몰 상품 구매 후기 데이터세트를 추천시스템의 입력으로 전달하기 위한 형태로 전처리하고, 전처리한 데이터세트를 다각도로 분석해본다. 또한, 각각의 모델들이 추천한 결과에 대해 검증 및 성능 비교를 수행하고 최적의 성능을 보이는 모델을 탐색하여 이후 해당 쇼핑몰에서 추천시스템 구축 시 어떤 모델을 사용하는 것이 좋을지를 제시한다.

The personalization recommendation system means analyzing each individual's interests or preferences and recommending information or products accordingly. These personalized recommendations can reduce the time consumers spend searching for information by accessing the products they need more quickly, and companies can increase corporate profits by recommending appropriate products that meet their needs. In this study, products are recommended to consumers using collaborative filtering, matrix factorization, and deep learning, which are representative personalization recommendation techniques. To this end, the data set after purchasing shopping mall products, which is raw data, is pre-processed in the form of transmitting the data set to the input of the recommended system, and the pre-processed data set is analyzed from various angles. In addition, each model performs verification and performance comparison on the recommended results, and explores the model with optimal performance, suggesting which model should be used when building the recommendation system at the mall.
