[[alternative]]On a Social Computing-based Evaluation Method for Improving Social Security in Virtual Communities

[[abstract]] 隨著時代變遷，人際互動管道轉移到網路虛擬空間中。觀察台灣地區使用網路情形中，網路使用者對虛擬社群(Virtual Community)的參與與日俱增。虛擬社群成員藉由不同的電腦中介傳播媒體，在網路上進行交友、購物、線上遊戲等互動行為。然而因著網路的匿名與連結特性，虛擬社群成員在享受便利的同時，亦承擔著不同程度的風險。本研究歸納個人、環境及情境等三層面建立本研究架構，探討虛擬社群使用者個人背景差異與網路互動行為的關係，並從中找出影響虛擬社群使用者網路互動行為之決策因素。最後以社交運算(Social Computing)為基礎，運用該決策因素提出一運算方法，求出評估新網友的互動安全值，為廣大的虛擬社群使用者提供安全評選網路互動對象之參考。[[abstract]] Instead of developing interpersonal relationship face to face, people keep social networking in the cyberspace over time. Network users increasingly attend in virtual communities in Taiwan. The users of virtual communities interact with each other through different computer mediated communication channels to keep social networking, shopping and playing games online. With the characteristics of being anonymous and connected easily on the internet, the users of virtual communities take risks while they take the advantages of the convenience. This thesis constructs of three aspects with individual, environment and situation in order to discuss the relationship between the personal backgrounds of the virtual community users and their interactive behavior online. The decisive factors for the interactive behavior of the virtual community users are concluded. On the base of social computing, an evaluation method is proposed with those decisive factors to form a security value to be a suggestion for the virtual community users while they evaluate the objects of encounter online
