Source favicon23:41 移动搜索行为的一些数据资料 » laolu

除了专利之外,Google的工程师们也发表了不少研究论文,主题范畴比较广泛。其中有篇《A Large Scale Study of Wireless Search Behavior: Google Mobile Search》(PDF文档),对移动搜索行为做了统计分析。

在XHTML(手机)查询中:平均每个查询输入的单词数量为2.3个(中位2,最大30,标准差1.6),平均每个查询输入的字符数为15.5个(中位14,最大502,标准差9.18)。在PDA查询中:平均每个查询输入的单词数量为2.7个(中位3,最大65,标准差1.5),平均每个查询输入的字符数为17.5个(中位16,最大396,标准差9.1)。这与以往桌面查询的数据(一为2.35[注1],一为2.6[注2])很接近。

据以往发表的有线搜索主题([注3]),前三个是“Commerce, travel, employment or economy”、“People, places and things”和“Computer or Internet”,色情查询只占10%不到。对照上面的数据,虽然XHTML和PDA的查询主题有些不同,但它们与有线查询的差异更大。

//原以为移动设备上输入比较麻烦,用户的查询可能更简短,结果好像不是;原以为手机绑定到个人,色情查询会更少,结果好像也不是。手机和PDA用户在查询上的不同,可能与用户群有关。如果在中国,PDA用户搜索的第一需求就是哪儿吃饭?

原文链接:Web 2.0 definition updated and Enterprise 2.0 emerges 原文作者:Dion Hinchcliffe @ 4:19 pm, November 5, 2006 在这周二举行的 Web 2.0 年会上给下一代的网络应用程序的概念做出了很重要的更新。因此,这次会议在准备阶段的主要事情不是将会议的名字改成 Web 2.0 峰会,而是更加确切的讨论 Web 2.0 到底是什么,什么让业界为它如此的如此的疯狂。 就在上周末,一份名为《Web 2.0 原理和最佳实践》的100页左右的新报告对外发布了,它主要由 Programmable Web 的 John Musser 撰写,同时还得到了 Tim O’Reilly 和 O’Reilly Radar Team 的大力支持。就像很多读者所知道的,O’Reilly Media 最早在2004年提出了 Web 2.0 这个概念,并且在2005年通过一份只有5页纸的短文(What Is Web 2.0)描述了它成功的设计模式和 Web 今天所浮现出来的商业模型。今天的这份新报告,并不是对以前那份短文的继续鼓吹,它是一份有用的商业报告,通过多种方式更加清晰的诠释了 Web 2.0。 首先,这份报告深入的阐述了正在改变中的 Web 给特定市场所带来的驱动力,这些改变 Web 的技术也被成功的应用到了今天的 [...]
