1、Together with the National Libraries of Scotland and Wales, the Bodleian Library in Oxford, the Cambridge University Library and Trinity Colleges library in Dublin, the British Library is now empowered to receive a copy of every U.K。 electronic publication。 This is a logical enough extension in the
2、digital age of its ancient right to receive and store all books, newspapers, magazines and other printed matter, but it is still achallenging task. The first full-scale Internet “crawl” was launched from the librarys West Yorkshirecomputer center shortly after the law took effect。 Covering 4.8 milli
3、on U.K. sites, it took three months to complete, with another two months required to process the 1 billioncaptured web pages。 The expectation is that the library will collect in a single year aboutthe same amount of material as its newspaper and periodicals archive has amassed over the course of thr
4、ee centuries (a costly program to digitize some 40 million of its 750million printed pages is now underway).Chief Executive Rolv Keating points out that when the initial crawl began, the projectrepresented a reassertion of what it means to be a library in the 21st century. Ten yearsago, there was a
5、very real danger of a black hole opening up and swallowing our digitalheritage. Keating says。 ”Millions of web pages, epublications and other nonprint itemswere falling through the cracks of a system devised primarily to capture ink and paper。Professor Niels Brugger, the head of the Center for Inter
6、net Studies at Denmarks Aarhus University, supports the British Librarys archiving project. “More and moreof our societal, cultural and political actives now take place either on the web or areclosely related to it he says. “Since the mid1990s, you simply couldnt be a university, a company or a poli

If want to documentour present or study our past on the web, get it into an archive before it disappears.”“Whenever Im asked why web archiving matters,” he continues, “I think of the BobDylan line from The Times They Are Changing The present now will later be pa

Capturing the past for posterity through web archiving matters just as much aspreserving other aspects of our cultu
9、ral heritage, whether its kitchen utensils, buildings, warships or collections of newspapers. Studies suggest that 40 percent of whats on it at any given moment is deleted a year later, while another 40 percent has been altered, leaving just 20 percent of the original content。”Almost every major nat
10、ional library in Europe now undertakes web arching。 Thoughthe scale and cost of such operations vary widely according to their individual remit。 The British Librarys project cost some 5 million to set up, the money coming entirely from its grant from the Department of Culture, Media and Sport。现在,大英图
11、书馆与苏格兰和威尔士国家图书馆、牛津大学的博德利图书馆、剑桥大学图书馆和都柏林三一学院图书馆一起,有权接收英国所有电子出版物的副本。在数字时代,这是一个合乎逻辑的延伸,因为它拥有接收和储存所有书籍、报纸、杂志和其他印刷品的古老权利,但这仍然是一项具有挑战性的任务.该法律生效后不久,图书馆西约克郡计算机中心启动了第一个全面的互联网“爬行”.它覆盖了480万个英国网站,花了3个月的时间才完成,另外两个月需要处理10亿个被捕获的网页。人们预计,该图书馆在一年内收集的资料量,将与它的报纸和期刊档案馆在过去三个世纪积累的资料量相当(一项耗资巨大的计划正在进行,将其7.5亿页印刷资料中的4000万页数字化
12、)。图书馆首席执行官罗尔夫基廷(Rolv Keating)指出,最初的爬行开始时,这个项目代表着对图书馆在21世纪意义的重申。十年前,我们面临着一个非常现实的危险:一个黑洞正在打开,吞噬我们的数字遗产。基廷说.“数以百万计的网页、电子出版物和其他非印刷品从一个主要用于捕捉墨水和纸张的系统的缝隙中滑落。”丹麦奥尔胡斯大学(Aarhus University)互联网研究中心(Center for Internet Studies)主任尼尔斯布鲁格(Niels Brugger)教授支持大英图书馆的存档项目。他表示:“我们越来越多的社会、文化和政治活动要么发生在网络上,要么与之密切相关.”“自上世纪9
13、0年代中期以来,如果没有网站,你就不可能成为一所大学、一家公司或一个政党。如果你想在网上记录我们的现在或者研究我们的过去,在它消失之前把它归档。“每当有人问我为什么网络档案很重要时,”他继续说,“我就会想起鲍勃迪伦(Bob Dylan)在他们正在改变的时代说过的话现在的现在以后会成为过去。”“材料正以前所未有的速度消失在我们的眼前,对于未来的历史学家来说,这些珍贵的原始材料也将随之消失,而未来的历史学家将试图揭示当下的真相。”通过网络档案为我们的子孙后代捕捉过去,就像保护我们文化遗产的其他方面一样重要,无论是厨房用具、建筑、军舰还是报纸收藏。研究表明,在任何一个特定的时刻,40的内容会在一年后
14、被删除,而另外40的内容会被修改,只剩下20的原始内容。现在欧洲几乎每一个主要的国家图书馆都承担着网络拱架的工作。尽管这些行动的规模和费用因其各自的职责而有很大差别。大英图书馆的这个项目耗资约500万美元,资金全部来自文化、媒体和体育部的拨款。If youre on Facebook, theres a roughly 0。04 percent chance the social media giantused you for a psychology experiment in early 2012, though youd have had no way ofknowing at the
15、time and indeed would only be finding out about the experiment thisweek。Thats what happened when researchers used nearly 700,000 Facebook users asguinea pigs for a study on “emotional contagion.” In brief, the study separated its usersinto two groups. One was subjected to a newsfeed of primarily pos

Over the weekend, observers blasted theexperiment as scandalous and disturbing, and according to The Guardian, one British MP has gone so far as to call for a parliamentary investigation into how
19、 it was carried out.Adam Kramer, Facebooks data scientist and a coauthor of the study, took to his ownFacebook page to offer a defense.“The goal of all of our research at Facebook is to learn how to provide a betterservice, Kramer writes。 “Having written and designed this experiment myself, I can te
20、llyou that our goal was never to upset anyone.” Still, he goes on to concede that those aimswerent made particularly clear and that the research conclusions “may not have justifiedall of this anxiety。” Thats probably an understatement。Most disturbing, though, is the fact that this sort of data manip

23、edings of The National Academy of Science)上的论文中写道,研究结果“表明,朋友通过在线社交网络表达的情绪会影响我们自己的情绪,据我们所知,这是社交网络大规模情绪感染的首个实验证据.换句话说,这项研究证实了Facebook重度用户早就知道的事实:你的朋友在Facebook上发布的内容可以对你自己的情绪状态产生切实的影响.Facebook一直无法控制了解到这项研究存在的用户的反应:人们很恼火。上周末,观察家们抨击这一实验是可耻和令人不安的。据卫报报道,一名英国议员甚至要求议会调查这一实验是如何进行的。Facebook的数据科学家、这项研究的合著者亚当?克莱
24、默(Adam Kramer)在自己的Facebook页面上为自己辩护.克雷默写道:“我们在Facebook进行的所有研究的目标都是学习如何提供更好的服务。”“我自己编写并设计了这个实验,我可以告诉你,我们的目标是永远不让任何人失望.”不过,他也承认,这些目标并没有特别明确,研究结论“可能无法证明所有这些焦虑都是合理的”。这可能是一个保守的说法.然而,最令人不安的是,这种数据操纵几乎肯定在Facebook的使用条款范围内。正如The Verge所指出的,每个Facebook用户都同意他们的信息被用于“内部操作,包括故障排除、数据分析、测试、研究和服务改进”.但Facebook不需要召集另外50万
