設計以本體論為基礎之影片註解分享促進協作學習
Ontology-Based Video Annotation Sharing for Supporting Collaborative E-Learning
摘要
在科技進步快速的時代而言，線上的學習系統儼然成為學習中不可或缺的一部分。然而，多數的線上學習系統是基於網頁教學資料庫的模式，這樣的方式讓溝通的流向侷限於讀者跟網頁之間，而這種傳統的溝通方式讓學生下載教材並且獨自研讀，也失去了與人分享學習心得的管道。教學資料庫裡的資源連結對於教學的資源並沒有語意上的描述，使得教學資源之間並沒有緊密關係連結，搜尋起來格外的不便，甚至會下載到雖為同樣檔名但內容卻不是我們想要資源。在學習成效方面，影片教學會來得比文字學習更能加深腦海中的印象，我們選擇影片串流與註解分享做為主題。因此，本論文提出了以本體論為基礎的影片與註解分享之知識交流平台，由於此平台透過分散式架構來讓每個使用者分享自己的學習影片以及對於影片的註解，由此也達到了硬體資源共享的目的與分擔影片串流之負擔。最後，此平台發展了與以往主從式觀念相左的點對點分散式架構，並賦予網路上該分享資源的語意化描述，進而使用者也能在與觀賞影片之間，共享個人的學習知識與心得，不用因為伺服器出問題而害怕自己分享上去的知識付諸流水。

In the rapidly technology enhancement, the e-learning system has become an important role of learning. However, the mainly e-learning system is web-based model with stores lecture resources in database. Consequently, user limited the flow communication between the reader and the web site, which is the traditional means the communication for students to download materials and study alone. It could lost the contact way to share the knowledge. The resources of database cannot link for another resource by the semantic description, so that there is a weak relationship between the links particularly in searching resources. When user downloads to the file but the content with the same name is not that we want the resource. On the other hand, video will enhance more impressive than the text learning, so we chose the video streaming sharing as the subject of our system. This paper proposes a ontology-based video annotation and the exchange of knowledge-sharing platform, as a result of this platform through a distributed architecture to allow each user to share their videos, as well as the study notes for the video. It can reach the hardware resource sharing and the purpose of sharing the burden of video streaming. Finally, the development of this platform with distributed peer-to-peer structure rather than the previous concept of master-slave, and users give the semantic description to share resources on the peer-to-peer network. While users watch videos, he can also share learning knowledge and experience.
