    Abstract: 對等式資訊系統雖然可以對所有上線的對等個體提供服務以達成資源共享及資訊交換的目的,但是因為原生性對等式資訊系統並沒有具備一個豐富資訊表達能力的結構藍圖,因此在共享及交換資訊的搜尋及內涵的分析上將面臨無法有效整合及彈性處理的窘境。結合語意網中本體論(語言)和規則組合(語言)來表達資訊結構藍圖以解決上述問題就成為最近學者最有興趣的研究議題。本研究將思考在進行電子化服務時,因為服務提供者及需求者條件設限的原因必須要解決於提供服務之前滿足這些條件限制的規範的議題。相對於現有資訊網服務是建構在全球資訊網的環境中,我們的電子化服務則以語意覆蓋的對等式資訊系統為主。我們將以本體論語言如OWL或RDF(S)及規則語言如RuleML來表達電子化服務設限的機制和規範原則,而服務設限的考量則是基於安全、隱私權、服務品質、及服務利基選擇等因素,因為本研究是在語意覆蓋的對等式資訊系統中進行,因此我也將同時解決資源定址轉換和對應的問題。另外我們將進而深入分析各種服務設限「規範原則」(內含本體論及規則組合)的管理機制,包括了有:「規範原則」的交換、彙整、優先度的設定、註銷、以及推論和執行,而在對等式資訊系統中因為允許各個資訊點的彈性加入或退出,所以在進行「規範原則」的管理上將更為複雜。我們的對等式資訊系統將建立在Planet Lab的分散式系統的環境中,因此我們將實際建置一個可以在語意網覆蓋對等式資訊分享系統中運作的實體平台並觀察及分析在此平台上各個資訊點其服務「規範原則」的管理及使用上所將面臨的各種狀況。
    In recent years, multimedia data are easily obtained from the network. Therefore, we can use these data to improve living quality. For example, when a user reads a novel, the family multimedia retrieval system can find a piece of suitable music to raise the reading atmosphere. Therefore, helping the users to efficiently find the wanted multimedia data becomes one of the important research issues. We consider three types of data, i.e., music, video, and time sequencing data, and design querying and mining methods according to their characteristics. Finally, we will integrate the results to build a system to raise the quality of life.
