Abstract

As the online commerce market continues to expand with an increase of diverse products and content, users find it challenging in navigating and in the selection process. Thereafter both platforms and shopping malls are actively working in conducting continuous research on recommendations system to select and present products that align with user preferences. Most existing recommendation studies have relied on user data which is relatively easy to obtain. However, these studies only use a single type of event and their reliance on time dependent data results in issues with reliability and complexity. To address these challenges, this paper proposes a recommendation system that analysis user preferences in consideration of the relationship between various types of event data. The proposed recommendation system analyzes the correlation of multiple events, extracts weights, learns the recommendation model, and provides recommendation services through it. Through extensive experiments the performance of our system was compared with the previously studied algorithms. The results confirmed an improvement in both complexity and performance.

매년 증가하는 온라인 상거래 시장과, 점차 다양해지는 상품과 콘텐츠로 인해 사용자들은 선택 과정에 어려움을 느낀다. 이에 여러 기업들은 온라인 쇼핑몰에서 사용자가 선호할 상품을 선별하여 제공하기 위해 추천 시스템에 대한 지속적인 연구를 진행하고 있다. 대다수의 추천 시스템 연구에서는 비교적 획득하기 쉬운 사용자의 이벤트 데이터를 기반하여 연구를 진행하였으나 한 종류의 사용자 행동만을 고려하기 때문에 사용자의 선호도를 파악하는 것에 오차가 발생한다. 이에 본 논문에서는 여러 종류의 사용자 행동 데이터의 상관관계를 고려하여 사용자의 선호도를 분석하는 추천 시스템을 제안한다. 제안하는 추천 시스템은 사용자의 사용자 행동 데이터의 상관관계를 분석하고 가중치를 생성하여 추천 모델을 학습한다. 실험에서는 기존 연구의 알고리즘과의 성능 비교를 통해 제안하는 시스템의 복잡도와 성능 향상을 확인하였다.
