網路世界的垃圾資訊與資源消耗

Abstract

近年來，各國皆開始提倡環保概念，但卻很少人注意到，其實在虛擬世界中也需要環保。使用者在虛擬世界中，使用著看似免費的網路資源，肆無忌憚的上傳內容、讓垃圾郵件占據電子信箱空間。然而，為了提供虛擬世界的資訊儲存、資訊傳播與交換，實際上是需要耗費許多實體資源的。 本研究提出了在虛擬世界也需要環保這樣的概念，統整現有的研究報告，並透過研究實證之。過去的研究報告指出，整個網路世界確實有著資訊爆炸的情形，資訊的產生速率甚至超過了儲存容量的成長速率。而企業為了提供這些儲存空間，耗費了許多的資源，尤其為了提供電力所消耗的大量不可更新資源，以及進一步造成的環境汙染。 接著透過研究實證了這樣的情形，以照片分享網站─Flickr 為例，使用內容分析法分析使用者創作內容，發現低品質的使用者創作內容充斥在整個虛擬世界中，垃圾郵件也是網路世界的ㄧ大問題，透過訪談方式進行垃圾郵件的研究，發現每個使用者的信箱平均有 80%的郵件是垃圾郵件。這些內容浪費大量網路資源，當然也造成實體資源的消耗。 本研究在最後提出建議，從使用者、網站與政府三方面下手，累積眾人的力量，舉手之勞，刪除垃圾郵件，或是在上傳使用者創作內容前先進行篩選，不僅能節省網路空間，也減少資源消耗與汙染的產生。

Recently, the idea of environmental protection attracts everyone's attention. However, few people notice that there also should be environmental protection in the virtual world. Users use the resources which provide by the website holder in the virtual world. For users, those resources are free, so most of users upload contents unbridledly, and let junk mails occupy the mailbox. Nevertheless, it actually uses a lot of physical resources to provide the information storage and information transfer. In this thesis, we remind the idea that there also should be environmental protection in the virtual world. In the researches presented before, digital universe is exploding. Moreover, the rate of information growth exceeds the storage available. For providing those storage spaces, companies use many resources, especially the consumption of non-renewable resources for providing electricity. It also resulted in serious environmental pollutions. And then, we prove it by conducting the research. We use content analysis and take Flickr as an example for analyzing user-generated contents (UGC). There are many low-quality UGC in the virtual world. Junk mail is another problem in the virtual world. We interview with e-mail users. According to the studies, the average rate of junk mail in one person's mailbox is 80%. Those contents waste plenty of internet resources and physical resources, and result in unnecessary environmental pollution. In the end of this thesis, in order to reduce the information garbage, we suggest that we solve this problem from three ways which are user, website holder, and government. Everyone could delete the junk mail frequently, and filter the contents before uploading. Therefore, it could not only save the network space, but also reduce the resources consumption.
