초록

추천 시스템은 과도한 정보제공으로 인한 정보 수용자의 결정 제약을 극복하고, 정보 제공자에게는 이윤과 평판을 최대화 시킬 수 있는 해결책으로 등장하였다. 추천 시스템은 다양한 접근법으로 구현이 가능하지만, 추천 대상 객체의 리뷰에서 생성되는 다양한 소셜 정보를 적절히 활용하는 방안은 연구되지 못하였다. 본 논문에서는 기존의 접근법과는 다르게 온라인 리뷰에서 생성되는 클러스터 정보를 이용하여 추천 시스템의 성능을 향상시키는 방식을 제안하였다. 제안하는 방식을 구현하고 실제 데이터를 활용하여 실험한 결과 기존의 방식들보다 성능이 월등히 향상됨을 확인하였다.

The recommender system (RS) has emerged as a solution to overcome the constraints of excessive information provision and to maximize profit and reputation for information providers. Although the RS can be implemented with various approaches, there is no study on how to appropriately utilize the information generated from the review of the recommended object. We propose a method to improve the performance of RS by using cluster information generated from online review. We implemented the proposed method and experimented with real data, and confirmed that the performance is significantly improved compared to the existing approaches.
