第六章 結論與未來方向
第三節 未來研究方向
本研究基於研究目的與方法以建立 SR 關鍵人物發掘模組，而研究過程中則 仍有許多可改善之處，將可供未來進行相關研究之參考：
(1)在文章分類過程之中，為符合微網誌之特性則採取 Ontology 方式來進行 分類，然而，容易導致各分類之文章數量不勻，因此，在少數類別資料集容易缺 少具顯著資料。因此未來研究將可採用不同之分類方式以提高各類文章數量，以 建構健全之資料集。
(2)本研究之使用者資料僅取得兩階層好友清單，其使用者資料再經過濾之後，
能夠使用之數量則是大為減少，其次，則是從學術單位進行發送，其類別容易過 於單純，多樣性較低，不易將各類別之文章採集。因此，未來在使用者清單採集 之上，可進階至三層好友資料來進行過濾。
(3)在本研究之關鍵人物定義之上，定義能夠影響使用者之對象可視為是關鍵 人物，因此，並未探究其影響力之程度，然而，對於使用者在社會網絡平台之中，
在不同議題互動之下也會具有不同程度的互動。因此，可在未來加入關鍵人物之 影響程度的定義來提高關鍵人物於不同類別中的排名與影響程度，以改善 SR 於 Top K 之中與傳統社會網絡特徵指標差異不大的狀況。
