    空难

    今天是圣灵降临日,全法放假,不幸的是发生了可怕的空难,整个下午的新闻的标题都是《飞机消失》。法航AF447航班从巴西圣保罗起飞, 预计中午抵达法国巴黎戴高乐机场,却在4点30(GMT时间)多却失去了联系,飞机在大西洋上空消失了。巴西和塞内加尔都立即派了空军开始搜索。就目前的消息看来,飞机上228人要生还的可能性相当渺茫。在空难的消息发布后,戴高乐机场立即就开辟了一个专门区域给受难者家属提供心理咨询和帮助,法国总统也在下午第一时间赶往机场表示遗憾和对受难者家属的支持。

    法航的安全记录一直一来都是很不错,最近几年却出了两次大事故。2000年的协和空难死了100多人,这次又是228遇难。我每次往返国内都是坐的法航的航班,希望法航能进一步提高飞行安全。

    下午我也在Twitter上关注了一下#Airfrance的搜索,Twitter的搜索还是做的很不错。特别是实时性。随时可以看见最新的更新。自己也试着更新了一下,更新结果可以立即出现搜索结果中。不知道Twitter是怎么做到的。就目前看来twitter在最终实时新闻上能更胜Google一筹。

    明天小滕第二次路考,希望小滕能顺利通过考试。

    嗯,不过这些都是offline做的,所以只要算法好且无需手动,数据庞大倒不算太大问题,不过对于实时更新的数据算法的及时性还是需要考虑的。我还有个想法,可以先根据关键字检索,然后将结果再聚类(比如根据链接组成的有向图),这样可能约减掉一些冗余或者噪声网页,网页的相关性也能提高。。。

    twitter应该就是用关键字检索,但是在这么庞大的数据中怎么实现快速检索这个技术要求挺高。

    是啊,下午看到这个新闻之后心里就一直很低落。

    也祝小滕考试顺利通过!
