Abstract

As web service technologies are widely used, there have been many efforts to develop approaches for recommending appropriate web services to users in complex and dynamic service environments. In addition, for the effective development of service mashups, service recommender systems that are specialized for service composition have been developed. However, existing service recommender systems for service mashups are not effective at recommending services in a personalized manner that reflect developers' preferences. To deal with this issue, we propose an approach that recommends services based on the similarities between mashup developers who have developed similar service mashups. The proposed approach is then evaluated by using the mashup data retrieved from ProgrammableWeb. The evaluation results clearly show that the proposed approach is an effective way of improving service recommendations compared to the traditional user-based collaborative filtering algorithm.

웹 서비스 기술이 각광받고 그 사용이 확대됨에 따라, 복잡하고 동적인 서비스 환경에서 사용자에게 적절한 서비스를 추천하는 방법에 대한 연구가 활발히 진행되고 있다. 또한 효과적인 서비스 매쉬업 개발을 위해 서비스를 추천하는 방법이 제안되었으나, 기존의 매쉬업 단위 서비스 추천 방식은 여러 매쉬업 개발자의 성향을 분석하여 그에 맞는 서비스를 추천하지는 못하였다. 이에 본 논문에서는 매쉬업 개발자들이 만든 서비스 매쉬업의 집합들과 추천 대상 개발자의 매쉬업 집합 사이의 유사도를 측정하고 유사한 매쉬업 집합들로부터 서비스를 추천하는 방법을 제안한다. 그리고 ProgrammableWeb에서 수집된 매쉬업 데이터로 실험한 결과를 비교 분석하여 본 연구의 방법이 사용자 기반 협업 필터링 알고리즘보다 높은 정확도와 재현율을 보임을 확인하였다.
