		<description><![CDATA[假设系统id是@tuibaike 对于普通用户，最简单的用法是只要将问题@给tuibaike，系统将问题rt给其他用户，并将答案返回提问人，就像现在很多人遇到问题就问@xiaolai一样。而实际上，系统先将问题rt给人肉分类员，由分类员对问题进行分类，打上标签后，再投递给相关“专家”（只是为了表述的方便，用“专家”来指代所有有可能提供答案的人）。 人肉分类员，就是fo了tuibaike的人。其首要任务是判断问题的类型，并打上相应标签。次要任务是，如果知道该问题可能由哪些专家回答，则rt给这些专家。最后，如果能够直接回答，直接给出答案。 系统还需要掌握一个“专家库”。专家库与问题分类的对应信息可由三个渠道获得。1、自动分析历史推，2、网友推荐，3、本人自荐。 希望这个系统能够解决“有选择的自动投递给相关领域专家”的目的。比如，英语学习问题问@xiaolai，经济学问题问@guodaxia，眼科问题问@goldgrape等。这样一方面问题可能更快得到解答，另一方面每个专家的TL不至于爆炸。 不确定的因素，有多少人愿意当人肉分类员，有多少专家愿意回答问题。 另外：有没有哪位朋友愿意实现这样的系统？<table class="wumii-related-items" cellspacing="0" cellpadding="2" border="0" width="100%" style="clear: both;">

			<content:encoded><![CDATA[<p>ESI(Essential Science Indicators)根据SCIE( Science Citation Index Expanded)、SSCI(Social Sciences Citation Index) 所收录的全球11000多种学术期刊文献纪录而建立的计量分析数据库系统。ESI为科研工作者提供了一种动态的、综合的、通过网络的研究分析环境。ESI从引文分析的角度，针对22个专业领域，分别对国家、研究机构、期刊、论文以及科学家进行统计分析和排序，主要指标包括：论文数、引文数、篇均被引频次等。可以从中了解在一定排名范围内的科学家、研究机构（大学）、国家和学术期刊在某一学科领域的发展和影响力，确定关键的科学发现，评估研究绩效，掌握科学发展的趋势和动向。</p>
<p>ESI收录的指标标准：</p>
<p>1. Highly Cited Paper：发表于十年内各领域中被引用次数Top 1%的文章</p>
<p>2. 国家排名：150个国家发表于十年内文章被引用次数Top 50%</p>
<p>3. 期刊排名：取4500种期刊近十年内文章被引用次数Top 50%</p>
<p>4. 科学家排名：发表于十年内文章被引用次数Top 1%的科学家</p>
<p>5. 研究机构排名：发表于十年内文章被引用次数Top 1%的研究机构</p>
<p>6. Hot Papers：发表于两年内被引用次数为各领域Top 0.1%的文章</p>
<p>7. Core Paper：在Research Front中跟某个Front所有相关的Highly Cited Paper的集合 </p>
<p>8. Top Papers：在国家/机构/研究员/期刊分类下看到的Top Papers，是这些分类下近十年被引用最多前1%的文章。(Top Papers = Highly Cited Papers + Hot Papers，是去掉重复后的总合)</p>
<p>9. 研究前线 (Research Front)：ESI 将国际过去五年中各个领域的论文，从其参考文献(references)及批注(footnotes)达到高引用门坎值的共同被引文献出发，通过群聚分析(Cluster Analysis)，产生聚类集合。有助于获知目前哪些领域的研究成果有重要发现，以及反映出当前科学家重点关注的方向。</p>
<p>ESI数据每两个月更新一次，每年6期。每年中间的更新，都包括前10年以及最近几个月的数据，而每年最后一期，只包括10年的数据（简单讲，年底那期是整10年没有零头的数据，其他期有零头）。每期可能调整部分期刊所属的领域。</p>
<p>ESI将期刊分为22个领域（Field），每本期刊只归于其中一个领域，而Multidisciplinary这个领域则包含诸如Science、Nature、PNAS及其他跨领域的约50种综合期刊。ESI会根据引用期刊来源而将这50多种综合期刊的单篇文章自动重新归类，每种期刊文章被重新归类的文章比例很不相同，平均约有一半文章被重新归类，而其中Science、Nature、PNAS等期刊有高达95%的文章被重新归类。 22个领域的定义见附录1。Mathematics的定义如下：</p>
<p>MATHEMATICS</p>
<p>The MATHEMATICS category is comprises journals dealing with:</p>
<p>    *  pure mathematics<br />
    *  applied mathematics<br />
    *  statistics and probability</p>
<p>而其他与数学相关的杂志被归于相应的领域，如Engineering中包括</p>
<p>    *  engineering mathematics<br />
          o mathematical modeling<br />
          o optimization techniques<br />
          o statistical methods in engineering systems</p>
<p>Physics中包括mathematical physics。</p>
<p>根据2010年12月公布的2010年第四期ESI，也即截止至2010年8月31日的数据，共收录11526种期刊。其中属于Mathematics的期刊有458种，完整列表见附录2。其中影响因子（IF）和5年影响因子（5-year IF）数据取自JCR 2010（Journal Citation Reports 2010），-1表示该期刊未被JCR 2010收录。另外，JCR 2010共收录7346种期刊，其中未被ESI 2010第四期收录的期刊有138种。</p>
<p>另外，考虑到部分数学相关期刊被ESI归为其他领域，因此，参考SCI分类方法，将Computational Biology，Interdisciplinary Applications，Mathematics，Applied Mathematics，Mathematical Physics，Statistics &#038; Probability等六类共241本期刊的ESI收录情况列出，见附录3。</p>
<p>SCI学科分类表见附录4，ESI所有期刊及分类见附录5（2010年12月数据）。</p>

		<description><![CDATA[　　这个著名的问题是这样的：（引自中文wiki： http://www.mirrorin.com/wiki/emgud2lr/aXBlZGlh/Lm9yZy93/aWtpLyVF/NCVCOCU4/OSVFOSU5/NyVBOCVF/OSU5NyVB/RSVFOSVB/MiU_3D/98） 这个游戏的玩法是：参赛者会看见三扇关闭了的门，其中一扇的后面有一辆汽车，选中后面有车的那扇门就可以赢得该汽车，而另外两扇门后面则各藏有一只山羊。当参赛者选定了一扇门，但未去开启它的时候，节目主持人会开启剩下两扇门的其中一扇，露出其中一只山羊。主持人其后会问参赛者要不要换另一扇仍然关上的门。问题是：换另一扇门会否增加参赛者赢得汽车的机会率？ 　　很多人（包括我自己）第一次看到这个题目的时候直观的感觉剩下的两扇门后面要么是羊要么是汽车，换不换门选中汽车的概率都是1/2，换门并不能提高选中汽车的可能性，那还是坚持最初的选择好了。而事实并不是这样。问题的答案是：如果不换，那么选中汽车的概率是1/3，如果换，选中汽车的概率是2/3。 　　网上已经有很多关于求解过程的讨论，这里我只讲我的理解。首先明确一点，主持人知道汽车在哪扇门后面并且他肯定会打开一扇有羊的门。否则如果主持人打开的是一扇有汽车的门，游戏就玩不下去了。既然主持人肯定会打开有羊的门，那么是否选择换另外一扇门就可以在整个游戏之前确定，也就是说，参赛者有两种策略，一种是随便选择一扇门并且不换门，另一种是随便选择一扇门并且在主持人打开有羊的门之后换选另外一扇门。下面只要分别计算这两种策略选中汽车的概率就可以了。 　　显然第一种策略选中汽车的概率是1/3，选中羊的概率是2/3。 　　第二种策略下可以根据第一次的选择分为两种互斥的情况，根据加法原理将两种情况下选中汽车的概率相加，就是第二种策略选中汽车的概率。 第一次选择的门后面是汽车，这个事件的概率为1/3。因为剩下的另外一扇门后面肯定是羊，即，是汽车的概率为0，因此这种情况下，最终选中汽车的概率为1/3*0=0。 第一次选择的门后面是羊，这个事件的概率为2/3。因为剩下的另外一扇门后面肯定是汽车，即，是汽车的概率为1，因此这种情况下，最终选中汽车的概率为2/3*1=2/3。 所以第二种策略选中汽车的概率为0+2/3=2/3。简单的讲，当参赛者以2/3的概率选中一扇有羊的门之后，主持只能将有汽车的门留给参赛者，如果换门，就可以选中汽车。 　　为什么我们会有最初的1/2困惑，并且相当一部分人看了&#8221;正确&#8221;的解答仍然坚持这样认为？我想了差不多一整天，我觉得关键是主持人打开的那扇门。因为主持人知道汽车在哪里，所以当他打开一扇有羊的门之后，剩下两扇门就不再是均匀分布了。 　　Wiki上关于这个问题的解答如下： 有三种可能的情况，全部都有相等的可能性(1/3)： 参赛者挑山羊一号，主持人挑山羊二号。转换将赢得汽车。 参赛者挑山羊二号，主持人挑山羊一号。转换将赢得汽车。 参赛者挑汽车，主持人挑两头山羊的任何一头。转换将失败。 在头两种情况，参赛者可以透过转换选择而赢得汽车。第三种情况是唯一一种参赛者透过保持原来选择而赢的情况。因为三种情况中有两种是透过转换选择而赢的，所以透过转换选择而赢的概率是2/3。 这个解答在我看来是相当的简洁明了，比我上面讲的更直接。之所以没有在开始引用这个解答，是因为有人有这样的疑问： 参赛者挑的时候，把山羊分为一号、二号，主持人挑的时候怎么不分一号、二号？肯定有问题嘛！ 这是表达上的小问题导致的误解，主要是句号的位置不正确。调整成下面这个样子估计会好些： 参赛者挑山羊一号。主持人挑山羊二号，转换将赢得汽车。 参赛者挑山羊二号。主持人挑山羊一号，转换将赢得汽车。 参赛者挑汽车。主持人挑两头山羊的任何一头，转换将失败。 　　昨天晚上看《数字追凶》（Numb3rs)，查理教授在课上讲了这个游戏。视频在这里：http://6.cn/watch/57604.html。<table class="wumii-related-items" cellspacing="0" cellpadding="2" border="0" width="100%" style="clear: both;">

			<content:encoded><![CDATA[<p>　　这个著名的问题是这样的：（引自中文wiki： <a href="http://www.mirrorin.com/wiki/emgud2lr/aXBlZGlh/Lm9yZy93/aWtpLyVF/NCVCOCU4/OSVFOSU5/NyVBOCVF/OSU5NyVB/RSVFOSVB/MiU_3D/98">http://www.mirrorin.com/wiki/emgud2lr/aXBlZGlh/Lm9yZy93/aWtpLyVF/NCVCOCU4/OSVFOSU5/NyVBOCVF/OSU5NyVB/RSVFOSVB/MiU_3D/98</a>）</p>
<blockquote>
<p>这个游戏的玩法是：参赛者会看见三扇关闭了的门，其中一扇的后面有一辆汽车，选中后面有车的那扇门就可以赢得该汽车，而另外两扇门后面则各藏有一只山羊。当参赛者选定了一扇门，但未去开启它的时候，节目主持人会开启剩下两扇门的其中一扇，露出其中一只山羊。主持人其后会问参赛者要不要换另一扇仍然关上的门。问题是：换另一扇门会否增加参赛者赢得汽车的机会率？</p>
</blockquote>
<p>　　很多人（包括我自己）第一次看到这个题目的时候直观的感觉剩下的两扇门后面要么是羊要么是汽车，换不换门选中汽车的概率都是1/2，换门并不能提高选中汽车的可能性，那还是坚持最初的选择好了。而事实并不是这样。问题的答案是：如果不换，那么选中汽车的概率是1/3，如果换，选中汽车的概率是2/3。</p>
<p>　　网上已经有很多关于求解过程的讨论，这里我只讲我的理解。首先明确一点，主持人知道汽车在哪扇门后面并且他肯定会打开一扇有羊的门。否则如果主持人打开的是一扇有汽车的门，游戏就玩不下去了。既然主持人肯定会打开有羊的门，那么是否选择换另外一扇门就可以在整个游戏之前确定，也就是说，参赛者有两种策略，一种是随便选择一扇门并且不换门，另一种是随便选择一扇门并且在主持人打开有羊的门之后换选另外一扇门。下面只要分别计算这两种策略选中汽车的概率就可以了。</p>
<p>　　显然第一种策略选中汽车的概率是1/3，选中羊的概率是2/3。</p>
<p>　　第二种策略下可以根据第一次的选择分为两种互斥的情况，根据加法原理将两种情况下选中汽车的概率相加，就是第二种策略选中汽车的概率。</p>
<ol>
<li>第一次选择的门后面是汽车，这个事件的概率为1/3。因为剩下的另外一扇门后面肯定是羊，即，是汽车的概率为0，因此这种情况下，最终选中汽车的概率为1/3*0=0。</li>
<li>第一次选择的门后面是羊，这个事件的概率为2/3。因为剩下的另外一扇门后面肯定是汽车，即，是汽车的概率为1，因此这种情况下，最终选中汽车的概率为2/3*1=2/3。</li>
</ol>
<p>所以第二种策略选中汽车的概率为0+2/3=2/3。简单的讲，当参赛者以2/3的概率选中一扇有羊的门之后，主持只能将有汽车的门留给参赛者，如果换门，就可以选中汽车。</p>
<p>　　为什么我们会有最初的1/2困惑，并且相当一部分人看了&#8221;正确&#8221;的解答仍然坚持这样认为？我想了差不多一整天，我觉得关键是主持人打开的那扇门。因为主持人知道汽车在哪里，所以当他打开一扇有羊的门之后，剩下两扇门就不再是均匀分布了。</p>
<p>　　<a href="http://www.mirrorin.com/wiki/emgud2lr/aXBlZGlh/Lm9yZy93/aWtpLyVF/NCVCOCU4/OSVFOSU5/NyVBOCVF/OSU5NyVB/RSVFOSVB/MiU_3D/98">Wiki</a>上关于这个问题的解答如下：</p>
<blockquote>
<p>有三种可能的情况，全部都有相等的可能性(1/3)：</p>
<ol>
<li>参赛者挑山羊一号，主持人挑山羊二号。转换将赢得汽车。</li>
<li>参赛者挑山羊二号，主持人挑山羊一号。转换将赢得汽车。</li>
<li>参赛者挑汽车，主持人挑两头山羊的任何一头。转换将失败。</li>
</ol>
<p>在头两种情况，参赛者可以透过转换选择而赢得汽车。第三种情况是唯一一种参赛者透过保持原来选择而赢的情况。因为三种情况中有两种是透过转换选择而赢的，所以透过转换选择而赢的概率是2/3。</p>
</blockquote>
<p>这个解答在我看来是相当的简洁明了，比我上面讲的更直接。之所以没有在开始引用这个解答，是因为有人有这样的疑问：</p>
<blockquote>
<p>参赛者挑的时候，把山羊分为一号、二号，主持人挑的时候怎么不分一号、二号？肯定有问题嘛！</p>
</blockquote>
<p>这是表达上的小问题导致的误解，主要是句号的位置不正确。调整成下面这个样子估计会好些：</p>
<ol>
<li>参赛者挑山羊一号。主持人挑山羊二号，转换将赢得汽车。</li>
<li>参赛者挑山羊二号。主持人挑山羊一号，转换将赢得汽车。</li>
<li>参赛者挑汽车。主持人挑两头山羊的任何一头，转换将失败。</li>
</ol>

		<description><![CDATA[　　Google Image Labeler是Google公司提供的一款在线游戏。没搞错吧，Google也开始做网游了？没搞错，确实是游戏，确实是Google提供的游戏。既然是游戏，我们还是先看一下玩法，再谈其他。 　　规则很简单，玩家甲到http://images.google.com/imagelabeler/登陆后，系统会随机指定另外一个在线玩家乙作为甲的搭档。然后在2分钟内，系统随机选取一张图片显示给两人，由甲、乙分别给这张图片打标签，可以打多个标签，但是不能使用系统禁用的标签（off-limits）。一旦两人所打的标签中出现一致的，系统会根据标签的&#8221;具体程度&#8221;给两人加上不同的分数，并显示下一张图片，继续打标签，直到2分钟结束。游戏结束后，会显示在这次游戏中所用到的所有图片，以及搭档给出的标签。标签越具体得分越高，比如下面这张图，如果两个人给出的标签是&#8221;sky&#8221;，那么可以得50分，&#8221;bird&#8221;可以得60分，&#8221;soaring&#8221;得120分，而&#8221;frigate bird&#8221;可以得150分。看上去有点麻烦，去http://images.google.com/imagelabeler/玩一下就很清楚了。 　　因为目前只有英文版，不但界面是英文的，打标签也只能用英文，对英文的要求还是比较高的。 　　Google搞这个游戏，其实是为了改进图片搜索的质量。目前图片的搜索或者说检索，仍然是一个世界级的难题。没有特别有效的方法，基本上还停留在根据颜色、纹理进行分类的阶段。Google通过这样一个游戏，可以集聚广大网友的力量，通过标签挖掘图片的真实信息，也就是常说的&#8221;人肉搜索&#8221;。如果还希望了解更详细的信息，请访问http://my.donews.com/jackiege/2006/09/10/bfabvbfwqfdovpayhpufsfhqvxoucfrqatdb/。 　　有时间就试一下吧。 http://www.feedsky.com/challenge/art/140687/feedsky/618618/~/gtsp/zt1/7d856/lnk.html<table class="wumii-related-items" cellspacing="0" cellpadding="3" border="0"  style="clear: both;">

上图你看到的并不是一幅巨型点阵艺术图，而是一道水帘，而水帘上能显示出图形，这个Bit.Fall（比特瀑布）来自于 <a href="http://sphericalrobots.org/">Spherical Robots</a> 的 Julius Popp（上图为模拟图，下面有视频）。这个水雕塑使用了128个同步电磁阀门（synchronized magnetic valves），将水流可以变成点阵图显示矩阵，一个计算机程序可以从新闻网站选择热门的关键词，将它们显示在这个透明的“信息窗帘”上，这个“信息流”寓意着信息的动态性和常变性。<span></span><br />

<p>4月30日：今天看到老徐自己说，“写了6700多个字，历时2个多月……”。那基本可以肯定，是GB字库，并且是逐个制作的。当然了，前提是老徐讲的是真的。</p>

		<description><![CDATA[　　我想，Email和IM应该互通，Google的Gmail和GTalk做到了。我想，RSS阅读器应该有一些智能的功能，来帮助用户更有效的组织RSS源，Google的Reader做到了。我想，浏览器要是可以在线同步配置文件就好了，Google的Browser Sync做到了。 　　我没想到，在邮件中居然可以直接打开Word、PDF、OpenOffice文档。我没想到，卫星上居然可以看到家门口的小路。我没想到，不安装Office，一样可以编辑Word文档，并且可以多人维护同一份文档。…… 　　还有拒绝Google的理由吗？或许，未来的PC，只需要网卡、屏幕、内存和浏览器。<table class="wumii-related-items" cellspacing="0" cellpadding="2" border="0" width="100%" style="clear: both;">
