Content Science for a Media-Rich Life
| Abstract in Chinese : 政府挑戰2008 國家發展六年計劃之重點產業目標（2003-2008）為兩兆雙星，其中“雙星”為“數位內容”與“生物科技”。“數位內容”產業不僅包括娛樂導向（電影、卡通、廣告動畫、和網路電玩等）及教育導向（數位博物館、數位典藏、網路學習等）的內容，更包括人類所有日常活動 (如電子商務、智慧型辦公室、遠距會議等)在內。就如此豐富的數位內容而言，”多媒體”一詞已不足以描述其涵意，而需要一套全新的“內容科學”來加以充份發揮。 內容科學是指探討在多媒體生活環境中，創造豐富數位內容所需的過程的科學，包括建置、分析、儲存、搜尋、處理、組織、管理、傳遞、呈現及互動所需的理論，方法以及技術。明顯地，內容科學的研究與資訊技術發展息息相關，但不僅限於資訊技術之範疇。所發展的技術及理論均須建構在最新的資訊技術基礎上，如新的介面、通訊裝置、多媒體處理平台等，但更重要的是內容科學研究須以人作為研究探討的核心。使用者的資訊需求須要了解與滿足，使用者行為，例如口語、手勢、以及資訊存取記錄等，都是內容組織、理解與運用時必須探討的課題。為此本計畫以使用者需求及資訊技術發展為主要思考角度，著重建構數位內容之組織、理解及運用等為核心之內容科學的研究。舉例來說，媒體的內容可能需要多模式的摘要及呈現形態，以適應使用者不同的終端元件及頻寬需求(如手機、PDA、個人筆記本、遊戲平台、數位電視、資訊家電等)。而使用者與數位內容的互動更可藉助視覺、聽覺、觸覺等更貼近人的感官的方式來達成。?跨不同型態的媒體的處理方法，例如利用同步的語音訊息來分析視訊內容，將更形重要，而為使用者在浩瀚的媒體內容中找到最急需的資訊更是關鍵目標。本計畫結合中央研究院與台灣大學的電機與資訊相關領域之研究菁英共同參與，其目的不在重覆不少已有相當成果的研究課題，而是要探討包括數位內容之知識結構、多模式內容之組織、使用者為核心之互動式媒體、及整合所有成果的可調整結構的軟硬體平台等新的研究課題。這些研究主題均以人類使用者為思考中心來規劃，由使用者觀點及瀏覽模式來探討內容的知識結構，由使用者的感覺喜好來組織多模式媒體的內容，並藉助對使用者的意圖的瞭解來發展內容與使用者的互動。”以人為本”是本計畫的中心思想。 本計畫所構思之“多媒體生活環境的數位內容科學”，係由台灣大學原卓越計畫“前瞻電信科技研究”之第三分項“建構於IP之無線多媒體技術及應用”衍伸出來，但其主題已不再限於無線通訊環境及多媒體之範疇，而將視野拓展到未來世界“數位內容”的無限天地，進一步探討“內容科學”的學理基礎。只有產業規劃，而沒有學理研究的帶動是不足的。藉由本計畫的執行，期待可建構世界一流的理論及學術基礎，並帶動整個台灣數位內容產業發展的深度與前瞻規劃。 |
| Abstract In English: The Taiwan government's “Challenge 2008” comprehensive six-year (2003-2008) national development plan calls for a “Two Trillions & Twin Stars” industrial development plan, in which one of the “Twin Stars” is “digital content” and the other is “bio-technology”. The digital content industry consists of not only entertainment-oriented (movie, cartoon, advertisement, networked computer games, etc.) and education-oriented (digital library and museum, digital archive, e-learning, etc.) content, but also all the activities of our daily life (e-commerce, intelligent office, teleconferencing, etc.). Such future digital content industry requires no longer just conventional “multimedia technologies”, but a whole new notion of “Content Science” for us to enter a completely new era. Content science herein is the scientific foundations including rationales, theories, methodologies and technologies that support the entire value chain of content production and utilization in a media-rich life: creation, analysis, storage, search, manipulation, organization, management, delivery, presentation and interaction. It is clear that research on content science should not be confined within the realm of information technologies. The theories, methods and techniques of content science should certainly all be based on the foremost IT innovations, such as new interfaces, software and media processing platforms. However, more importantly, the research on content science has to be also based on various human perspectives. Users' information needs have to be realized and fulfilled. Users' behavior patterns, such as spoken voice, gestures and statistics of access logs, should be taken into consideration in the study of content organization, understanding and utilization. The project is, thus, aimed to develop a solid scientific foundation of content science with the focus on content organization, understanding and utilization from both human and IT perspectives. For example, media content may need multi-modal summarization and presentation formats for different terminal devices and bandwidth requirements (e.g., cell phone, PDA, PC, game console, digital TV, and home appliance), and user-content interaction can be achieved with various new approaches including visual, auditory and tactile senses such that the content is more compatible to human perception. Cross-media processing becomes more important in, for example, handling video content based on the synchronized voice information. In addition, retrieval of the desired information from a plenitude of content over the networks to fit each user's need will be extremely important. The team members of this project include an elite group of leaders in information science and engineering from both National Taiwan University and Academia Sinica. This project is not merely to reiterate the well-studied research topics, but to explore in depth several key research areas involved in advancing the state-of-the-art of content science, including content semantics, multi-modal content organization, user-centric interactive media and reconfigurable multimedia system-on-a-chip. All these directions are human-centered, to analyze the content semantics from users' perspectives, to organize the contant based on user's attention and preference, and to develop user-content interaction by understanding the users' intention. This project, entitled “Content Science for a Media-Rich Life”, is an extension from the Program for Promoting Academic Excellence of University Project (PPAEU) of National Taiwan University, “Advanced Technologies for Telecommunications (B), sub-project (III): Wireless Multimedia over IP-Technologies and Applications”. The scope of the project is, however, no longer limited to wireless and multimedia environment, but instead looks into and beyond the present world of digital content, considering the whole notion of “content science”, with a goal to drive the content industry of the country in the future. “Digital Content” is the focus of the industrial development target of the government. However, without scientific research, the industrial development plan won't be successful. With the efforts made by this project, we hope to elevate Taiwan into a world elite class in the digital millennium, and help the government attain its national goal of developing a digital Taiwan and transforming Taiwan into a “green silicon island”. |
