    摘要: 伴隨著資訊科技之發展,各式各樣的物件在網際網路上迅速的累積,資訊過量成為主要的問題。因此,如何在大量的資料中,精確地推薦有用的資訊給使用者,即成為極具挑戰的研究課題。合作式推薦是其中一個解決資訊過量的方法;然而,隨著應用規模的成長,現階段合作式推薦系統所面臨的資料型態、處理模式與處理規模,都與過去單純的資料環境有著極大的不同,也導致現有技術有其侷限性。為了克服該問題,本計畫以三年為期研發一下世代合作式推薦系統。 在本年度計畫執行過程中,我們已完成預定完成之研究項目,分別為具不確定資料環境之子空間天際線查詢處理、高維度空間之任意子空間KNN查詢及具高準確率之鏈結樣式社群探索技術,並已發表於國際一流會議。本期中報告茲就本年度所完成的研究成果進行報告。
    With rapid growth of the Internet technology, the information overloading starts to be a challenge. Therefore, an efficient and effec-tive approach to assist users to precisely get the useful information from the massive data-set is needed. The collaborative recommenda-tion mechanism is a popular solution to solve this problem. However, with the growth of the scale of applications, nowadays collaborative recommendation systems have to deal with dynamic and fast growing environments, in which the existing techniques become ineffi-cient and ineffective for high-quality recom-mendation results. Therefore, the advanced techniques for collaborative recommendation become important research issues to further study. In this progress report, we report three research results we achieved in this year. They are (1) efficient computation of sub-space top-k probabilistic skylines on uncertain data, (2) enhancing the accuracy of multimedia data retrieval by an online classifier, and (3) dis-covering link-pattern based communities by classical clustering methods.
