Abstract

Many personalized services that provide users with adaptive information according to users' preferences have been researched and developed. Push services are especially expected to be more economic impact because push services satisfy user's potential needs even if the user does not require anything. In this paper, we propose Semantic Web approach in order to enhance the performance of push services. Our approach provides infrastructure to recommend contents based on semantic association by enabling information of contents and user preferences to be described on service-specific ontologies that reflect features of each service. In addition, our approach can recommend users with adaptive information based on information represented in our description model. Our approach enables information of contents and user preferences to be described with rich expressiveness, and it provides semantic interoperability.

사용자 선호에 따라 적합한 정보를 제공해 주는 개인화서비스에 대한 많은 연구와 개발이 진행되어왔다. 특히 푸시서비스는 사용자의 적극적인 요구가 없더라도 사용자가 관심 있어 할만한 정보를 제공함으로써 사용자의 잠재요구를 충족시켜준다는 측면에서 경제적 효과가 클 것으로 예상되고 있다. 본 논문에서는 이러한 푸시서비스의 성능을 향상시키기 위한 방법으로 시맨틱웹 기반 푸시서비스 기법을 제안한다. 제안방법은 서비스의 콘텐츠 정보와 사용자의 선호정보를 각 서비스의 특성을 반영하는 서비스 온톨로지 상에서 기술되어지도록 함으로써, 의미적 연관성을 기반으로 콘텐츠를 추천할 수 있는 기반구조를 제공한다. 또한 시맨틱웹 기반 푸시서비스 시스템은 제안방법에 의해 기술된 정보를 기반으로 사용자에게 적합한 콘텐츠를 추천하는 기능을 제공한다. 제안방법은 기존 연구들에 비해 콘텐츠 정보 및 사용자 선호정보를 기술함에 있어 풍부한 표현이 가능하고, 의미적인 상호운용성을 제공한다는 장점이 있다.
