    • 當傳統面對面的社交活動延伸到社群網路時，便產生許多新的應用，它不只維繫了人與人之間的關係，並且擴大了個人社交圈的範圍。在這類的網路社群中，若是有一種人具有說服他人與影響他人的能力時，這種人便稱為網路熱門意見領袖(iPOL)。
    本研究針對訓練後的網路熱門意見領袖，開發幾個子系統，以便提升他們的曝光度和增加他們的跟隨者。同時，也進一步對網路熱門意見領袖的影響力進行分析。在我們的研究中，電子名片用來提升社群曝光度，IPS和AVOD用來增加社群跟隨者。其中，IPS能夠即時的處理文字、聲音或影片檔案，加強跟隨者使用上的便利，讓更多的跟隨者願意參與。AVOD則提供多媒體影片，藉以吸引更多的跟隨者參與。最後，在iPOL的影響力分析上，我們以同性戀社群為探討案例來評估網路熱門意見領袖（iPOL）的影響力。此案例在傳遞HIV相關資訊的有效性、提高匿名HIV檢測的頻率，和減少使用網路的男男性接觸者間的危險行為上，具有相當的果效。

    Traditional face-to-face social activities, when extended to the Internet community, brings forth many new applications. They not only help maintain the relationship among people but also expands the range of personal social circle. In such a social network, a person possessing the capability of persuading people and influencing them is called the Internet Popular Opinion Leader (iPOL).
    This study developed several subsystems for trained iPOLs in order to enhance their exposure and increase their followers. It also further analyzed the effect of iPOL. In our study, electronic name cards were used to enhance social exposure, then IPS and AVOD were used to increase social followership. IPS can handle text, sound, or video files in real-time, making it more convenient for followers to use, and this attracts more followers to join in. AVOD attracts participation of more followers by providing multimedia films. Finally, with regard to impact analysis of iPOL, we studied the gay community in order to assess the impact of iPOL. This case was considerably effective in disseminating HIV-related information, improving the frequency of anonymous HIV testing, and reducing high-risk behavior among Internet-using MSM.
