编者按:梅耶尔入主雅虎之后,一切都显得顺风顺水,然而有一件事令她不快——微软
和雅虎的搜索引擎合作效果令人失望,梅耶尔希望退出合作,但是鉴于已经签署的十年
协议,雅虎陷入了被动。近日雅虎提交的监管文件,显示和雅虎和微软在搜索合作上激
烈抗争的内幕。Mitbbs.com
2010年,作为互联网业务“门外汉”的卡茨执掌雅虎,她急功近利地和微软签署了搜索
引擎合作协议,雅虎将放弃自有搜索,后台外包给微软的必应系统,作为回报,雅虎获
得搜索广告收入的大成,此外继续掌握高端客户的广告销售合作。Mitbbs.com
然而微软以收入换市场份额的努力,以失败流产。三年之后,谷歌仍然牢牢掌控了美国
搜索市场,市场份额几乎保持在三分之二左右。微软和雅虎的搜索份额之和,并未发生

c***z 发帖数: 6348 | 6 哦,我大概知道了,谢谢老大了!
但是我们最后会要和comScore的数据对比,如果结果相差太远,口才再好也没有法子
:( |
|
c***z 发帖数: 6348 | 7 对,就是要assign weight,但是完了之后要再和comScore的结果比照
一个巨大的困难是panel里面只有一部分记录有需要的变量,比如10%的人有性别的记录
如果采用这个子集来做weight整个panel,那么又会有额外的bias进入,这样的
classification怎么弄这个?能提供一点思路么,或者paper连接也好,谢谢啦 |

35,000. That’s the maximum potential number of Fire Phones Amazon has sold
so far, according to an estimate by The Guardian’s Charles Arthur.
Using data from Chitika’s ad network and Comscore’s smartphone user data,
Arthur came up with a figure that, while not definitive, gives us a sense of
how many Fire Phones are actually being used in the wild. And if it’s even
vaguely accurate, it’s a terrible result for Amazon.
It wasn’t hard to see the writing on ... 阅读全帖 |

Last month, New Oriental Education, China’s largest provider of private
educational services, and Tencent, the leading texting provider in China
with nearly 500 million users on its WeChat app, agreed to launch an
integrated, chat-centric education service. The question every university
should be asking is: What does this mean for online learning?

l**t 发帖数: 10440 | 14 美国知名财经杂志《商业周刊》网络版今天刊文称,谷歌周二宣布推出其Buzz服务,目
的是向加强Gmail等业务的社交网络功能,并最终提高其网络广告收入。但综合各种情
况,谷歌Buzz并无法从Facebook、Twitter等社交网站中抢走大量用户。
屡败屡战
多年以来,谷歌一直希望提高其社交网络服务实力。但截至目前,谷歌这一努力并没有
取得成功。2004年,谷歌推出了Orkut社交网站。自那时以来,Orkut仅在巴西等少数国
家受到欢迎。2005年谷歌收购了年轻手机用户好友行踪服务商Dodgeball,但已于去年
正式关闭该服务。
尽管如此,谷歌仍希望在社交网络业务领域内扮演重要角色。谷歌周二对外宣布,将推
出名为“Google Buzz”的社交网络服务。谷歌称,谷歌Buzz可视为“谷歌式的共享方
式”,即用户可在谷歌Gmail邮件服务中同他人分享各类信息(图片、网络链接及其他内
容),同时可自动加载好友的活动信息,并为用户自动建立相应邮件发送列表。
从功能上看,谷歌Buzz服务同Twitter、Facebook等媒体网站的同类服务颇为相似。由
于谷歌擅长于向用户发布针对性很强的网络广告... 阅读全帖 |
