谷歌对搜索算法进行重大修改 新颖度算法上台

Google local time in the United States on Thursday announced that its search engine algorithms to make major changes. The new algorithm will increase the time factor. This change will make 35% search results change.

Google made this change is because nowadays people hoped that from the Twitter or other website to search for real time news， but Google‘s search algorithms are unable to do this. The results show there is a little outdated， such as when the search for“ Oscar Award” to find out the year awards when specific time， the search result is a past awards content etc.

Google will a new algorithm called“ freshness algorithm” ( new algorithm )， using Google ’s“ caffeine” webpage index system faster capture network information， and provide real-time search results.

Google annually on its search algorithm to make more than 500 revisions， but most modify only affects a very small part of the search results. On a larger scale modifications occurred in February of this year， when Google removed some low quality web sites， such as information farm site， affected search results reached 12%.

The new algorithm is implemented， for recent events， such as the Oscar prize or the presidential election， the new updated information will be ranked in the forefront of the search results， as is the use of Google news search tools that use time. In addition， more frequent updating topic， such as the new iPhone ‘s comment， will also appear on comments.

For those not time sensitive content search results， such as“ how to change a tire” or“ banana bread ”， Google said their algorithm can know what is most consistent with the result of time， time will not be affected.

谷歌在美国当地时间星期四宣布对其搜索引擎的算法作出重大修改。新算法将加重时间因素的影响。这一改动会使35%的搜索结果产生变化。

谷歌作出这一改变是因为现今的人们更希望从Twitter或者其它网站搜索到实时的消息，但谷歌目前的搜索算法则无法做到这一点。显示的结果总会显得有点过时，譬如当搜索“奥斯卡奖”以找出今年颁奖晚会的具体时间时，得到的搜索结果却是一项过去颁奖晚会的内容等等。

谷歌将新算法称为“freshness algorithm”(新颖度算法)，利用谷歌的“咖啡因”网页索引系统更快的捕捉网络信息，并给出相关的实时搜索结果。

谷歌每年都会对其搜索算法作出超过500次的修改，但大多数修改仅仅会影响极少部分的搜索结果。上一次较大规模的修改发生在今年2月份，当时谷歌清除了一些低质量的网站，比如信息农场网站等，受影响的搜索结果达到了12%左右。

新算法实施后，对于近期发生的事件，如奥斯卡奖或者总统大选等，最新更新的信息会排在搜索结果的前列，就像是使用谷歌搜索资讯时使用时间工具那样。此外，较频繁更新的话题，如对新iPhone的评论等，也会显示靠前的评论。

对于那些对时间不敏感的内容搜索结果，如“如何更换汽车轮胎”或者“香蕉面包的做法”之类的，谷歌表示他们的算法能知道什么是最符合答案的结果，时间此时将不受影响。
