部落格內之主動資訊擴散模型

Abstract

部落格是近年來在網際網路上發展的網路服務之一。使用者可以透過簡單的操作方式發佈各種類型的資訊，將資訊擴散到不同的部落格內。透過清楚的時間記錄，資訊擴散的方向與先後順序可以被清楚的定義出來，透過部落格上的文章內容及其回應與引述功能，也能了解不同部落格之間的關係。在部落空間內，資訊擴散可以是被動或主動地完成，在此，我們提供一可主動資訊擴散的模型，藉以改善部落空間內整體的資訊擴散效能。 透過實際資料以及實驗模擬，我們比較各種不同的主動擴散策略之成效；使用者透過不同的資訊擴散策略可達成其個別目標。分析單一主動擴散之效能亦可清楚了解個別主動擴散對於整體擴散速率的影響。本實驗並嘗試提供分析主動資訊擴散成本的方法，以便更為客觀地分析節點在主動資訊擴散上的效益。

Weblog is a journal that is frequently updated and normally reflecting the views of the blog’s creator. Users can easily create content in any type of information. Blog users create content and deliver their thought in their blogs. Information diffusion in blospace is traceable because of time records. we can also realize the relationship between blogs through the links and articles in the blogspace. Diffusion of information can be both active and passive diffusion in blogspace. Information flows among blogs and the diffusion is obvious. We provide a new model for information diffusion in blogspace. Efficiency of diffusion rate raises up under active information diffusion. We simulate the diffusion process in blogspace and compare the efficiency of active information diffusion under different strategies. Different strategy leads to different outcome; diffusers can select a strategy to reach their own goals. We also analyze the efficiency of active diffusion under different strategies. The efficiency of active diffusion greatly affects the speed of information diffusion. Finally, we provide a method to evaluate if the active diffusion is worthy to each node.
