Intelligent retrieval for best satisfying users search intensions still remains a challenging problem due to the inherent complexity of real-world semantic web applications. Usually, a search request contains not only vagueness or impre-cision, but also personalized information goals. This paper presents a novel approach which formulates one's search(More)
