【最棒的学术搜索引擎】Wolfram Alpha 图文评测

by CrazySky

咳咳,这次本人介绍的应用---没错是应用!这评测我们不谈游戏,只谈应用!
好了这次为大家带来的是一款超级强大的学术搜索引擎------Wolfram Alpha
想必大家对Wolfram这个名词都很陌生吧,所以呢就首先为大家普及一下沃尔夫勒姆研究公司(Wolfram Research, Inc.)
沃尔夫勒姆研究公司(英语:Wolfram Research, Inc.),也称 沃尔夫勒姆 公司,是当今世界科技计算软件的主要开发商之一。公司由科学家 史蒂芬·沃尔夫勒姆 创建。史蒂芬·沃尔夫勒姆也是公司的创建者和首席执行官。(来源:维基百科)

—————————————————————————————————————————————————————————
看了上面的介绍各位也许会感到迷惑,区区一个搜索引擎凭什么说它超级强大?
也许各位也会拿中国最大的搜索引擎---百度来与之比较,但是很遗憾,我必须告诉大家的是:百度在Wolfram Alpha面前就相当于朝鲜在中国面前一样----根本就无法相提并论,甚至连维基百科这种Niubility的搜索引擎也比不上Wolfram Alpha
我为什么如此推崇这款软件?请大家慢慢往下看吧!

做一个简介:
WolframAlpha是开发计算数学应用软件的沃尔夫勒姆研究公司开发出的新一代的搜索引擎,能根据问题直接给出答案的网站,用户在搜索框键入需要查询的问题后,该搜索引擎将直接向用户返回答案,而不是返回一大堆网页链接。(来源:百度)
好吧首先来看看主界面(好吧我觉得只看这键盘的按键就够了。。简直是超级人性化的设计啊)

搜索的loading画面做得还是挺不错的

再尝试一下它的搜索能力(本人手贱打了Mao Zedong这一串字母[拼音?]没有百度那样繁琐的N多个的网页链接,Wolfram Alpha所呈现出来的是直观、详细的数据
比如说下图的表格
【最棒的学术搜索引擎】Wolfram Alpha 图文评测
还可以进行表格的切换

本软件不像百度、Google那样的主流搜索软件来通过手动复制文字,本软件可以通过长按自己想要摘录下来的句子,然后就出现了下面的一些列选项
【最棒的学术搜索引擎】Wolfram Alpha 图文评测
比如说我选择最后一项“储存于相册中”,于是乎我就会在相册里找到这个,十分方便、快捷

好了,以上就是Wolfram Alpha的作为一款普通搜索引擎的功能。下面我就要为各位介绍作为一款学术搜索引擎的功能了!
大家可以看到上面所有图中的左上角都有一本书,我们点进去看看
进入之后我们可以看到各个领域的知识Example

然后我随便点了个Chemistry,里面有无数的化学常识(很显然,大部分都是大学的。。于是我只能找了个基本的铝和氧气的化学方程式来示范了)
【最棒的学术搜索引擎】Wolfram Alpha 图文评测
按一下那个化学方程式就可以更深层次的了解了
【最棒的学术搜索引擎】Wolfram Alpha 图文评测
这些是反应的各种写法
【最棒的学术搜索引擎】Wolfram Alpha 图文评测
往下翻的话会看到反应物的各项数据(熔点、沸点、摩尔质量之类的)相当的齐全

不过网页版的操作起来确实有点小小的蛋疼,比如说我又搜毛爷爷。。。表格就显示不全

缺点:不支持中文 (大哥你这一句Wolfram Alpha不支持中文是用来卖萌的么。。)

总结:这款超强的学术搜索引擎搜到的不仅是数据,而且是知识,强烈推荐!虽然没有中文对我来说有点小遗憾,不过还是能勉强看懂18¥有点小贵,不过我是从来没见过这货冰点,所以说有兴趣的朋友可以收了试试这次的评测就到这里,我们下次再见
