近年來部落格空間成長快速，在人們的數位生活中漸漸不可或缺。為了瞭解部落格的社群互動，目前已有許多部落格相關的研究成果發表。不過關於台灣部落格空間的網絡分析卻仍然有限，因此為了探索台灣部落格的網絡變遷，本研究以台灣的「部落格觀察」網站，於2008年10月26日、2009年9月6日、與2010年6月27日的排名資料為基準，分別挑選「台灣個人榜」前一百名部落格為研究樣本。首先，我們分析這三個樣本群集的基本資料，比較它們特性上的差異；然後，再根據於2008年11月1日、2009年9月11日、與2010年7月2日所蒐集到的樣本部落格首頁上的朋友連結名單，分別篩選與繪製出這三個時點的朋友網絡拓撲；接著，我們再利用中心性分析與k-核心分析比對這三個時點的網絡變遷。研究結果發現網絡分析的各種中心分別落於「網路應用」、「圖文」、以及「美食」等前三大社群；再與國外的部落格發展相較，我們則發現「網路應用」社群同樣是熱門的趨勢；相較於西方民主國家活躍的政治部落格，「社會評論」社群的連結則似乎受到侷限；至於「圖文」與「美食」社群則是台灣部落格特有的發展。

Recently, the blogosphere has been dramatically blooming and becoming indispensable in our digital lives. Nowadays, there have been many published researches about the blogosphere. However, the network analyses of Taiwan blogosphere are still limited. Thus, in this research, we tried to investigate the network changes of Taiwan blogosphere. Based on the rank list maintained by the Taiwan website, “Blog Look,” we took the Top 100 Taiwan personal blogs, on 26 October 2008, 6 September 2009, and 27 June 2010, respectively, as three clusters of our research sample. First, we conducted basic statistics of the three sample clusters, and compared the differences between them. Then, we collected all the blogrolls of the Top 100 blogs, on 1 November 2008, 11 September 2009, and 2 July 2010, respectively. Therefore, we sifted and figured out three blogroll network topologies at the three time points, respectively. Upon the three blogroll network topologies, we applied centrality and k-core analyses to explore the network changes of Taiwan blogosphere. Based on the analytical results, we found that the communities of networking application, picture article, and cuisine, respectively, are the top three communities and locate at a variety of topological centers of Taiwan blogosphere. Furthermore, compared to the blogosphere around the world, we found that the community of networking application fits in the blogging trend around the world, the community of societal comment is less connected than popular political blogs in western democratic countries, and the communities of picture article and cuisine are special developments of Taiwan blogosphere.
