在目前的網際網路中，點對點(P2P)網路的應用扮演了一個重要的角色。由於在點對點網路架構下，檔案分享系統中檔案的數量以及來源大量增加，造成使用者必須花費更多的時間找尋想要的資源，因此搜尋功能就顯得格外地重要。BitTorrent(BT)作為一個點對點檔案分享系統，用戶量不斷增加，已逐漸成為網路頻寬的主要消耗者之一，但是其協定中沒有提供搜尋的功能，而且檔案分散於各個檔案發佈站之間，以及各發佈站之間無法有效搜尋彼此擁有的檔案資源，導致使用者查詢時效率不佳。因此本研究期望建立一套語意式搜尋機制來幫助使用者解決上述的問題。藉由使用語意網技術(Semantic Web)，針對BT檔案分享系統設計本體論，進行資源描述和建立簡單的分類，利用檔案的metadata來提供搜尋的功能以及彙整各檔案分佈站的檔案資源，做為上述議題的一個解決方案，讓使用者能夠更有效率地找到更完整的資源。 / In current World Wide Web, P2P network application plays an important role. Because the number and origin of files increase greatly in file sharing system under the architecture of P2P, causing users to spend more time searching for the resources they want. Therefore, the search function appears especially important. BitTorrent(BT), one kind of P2P file sharing system, has more and more users and becomes one of the biggest consumer of the network bandwidth. But it doesn't support any search function and shared files disperse between many web sites. Furthermore, these web sites can't exchange the shared files they own efficiently. These problems result in inefficient search performance. My research expects to propose a semantic search method to solve the problems mentioned above. By the means of Semantic Web technology, we design the ontology of BT file sharing system to describe the resources and establish simple taxonomy. In addition, using the metadata of files to provide BT for search function and collect the shared files between web sites. Let users find the shared files more efficiently and completely.
