摘要: 隨著資訊爆炸時代的來臨,個人化推薦服務成為各類資訊系統中,非常重要的元件。以中興大學為主的研究團隊,從2006年開始,針對圖書館的圖書借閱服務,建立了一個以個人本體論為基礎的圖書館推薦系統,並將之命名為PORE ( Personal Ontology REcommender System)。這個系統是目前所知,第一個將個人本體論應用在圖書推薦的系統,具有相當的前瞻性。然而,在實作上,這個系統仍有需要改善的地方。本論文便是針對其視覺化展現推薦結果,以及合作式過濾的效能,提出改善。 在推薦結果視覺化方面,本論文使用開放原始碼的工具OntoSphere 3D,將個人本體論以及其與推薦圖書的關係,以3D的方式呈現。在三度空間中,物件可以旋轉、收縮、移動、變化形狀,以更豐富的視覺效果,提供讀者更真實的查閱界面。在合作式過濾的執行效能方面,我們也透過預先分群的方式,將有重疊借閱分類紀錄的讀者先歸為一群,並在該群讀者中去找相似的讀者。在實驗中,新的演算法,將可以節省96%的運算次數。本研究的成果,使PORE系統的運作更為快速,並具有優良的讀者介面,對系統的推廣,將有極大的幫助。
In the era of information explosion, personalized recommendation services have become an important component for most information systems. Since 2006, the research team mainly consisting of researchers at National Chung-Hsing University (NCHU) proposed a recommender system called PORE (Personal Ontology REcommender System) for recommending library collections. The system is the first one in using personal ontology for library collection recommendation. However, there is still some weakness which should be improved in the PORE system. This thesis proposed methods on improving visualization of recommended results and the performance of collaborative filtering recommendation. For visualization of recommended results, this study developed a 3D interface using an open source tool, OntoSphere 3D, to show personal ontology, the relationship between personal ontology, and the recommended library collections. In the 3D model, users can rotate, shrink, or move recommended objects. As a result, the 3D interface provides a more user-friendly interface to the users of the PORE system. For the performance improvement of collaborative filtering recommendation, we proposed a method that clusters users with overlapping personal ontology and then finds similar users in the group. The experimental results show that the proposed method can save up to 96% of computation.
