搜索引擎是上网最重要的入口,掌握了搜索引擎就掌握了用户,掌握了流量,从而获得巨额广告收入。所以各大互联网公司纷纷推出了搜索引擎搜索引擎如何能够搜得更准是其最重要的目标,你肯定每天用搜索引擎找信息,却不一定每次都能精准找到。
Search engine is the most important access to Internet. Mastering the search engine has mastered the users and mastered the traffic volume, thus obtaining huge advertising revenue. So the major Internet Co have launched a search engine search engine how to search more accurate is its most important goal, you must use the search engine to find information every day, but not always be able to accurately find.

Information is not searched, but it is probably: you open the search engine the wrong way! How can we make the search results more accurate? There are many problems involved.

搜索引擎用户输入的查询请求非常简短,查询的平均长度是2.7个单词。如何从如此短的查询请求里获知隐藏其后的真实用户需求?这是搜索引擎首先需要解决的非常重要的问题。如果不能获取用户真正的搜索意图,搜索的准确性无从谈起,即使后续内容匹配算法再精巧也无济于事。

The query requests from search engine users are very short, and the average query length is 2.7 words. How to learn the hidden user needs from such a short query is a very important problem that the search engine needs to solve first. If you can not get the real search intention of users, the accuracy of search can not be mentioned, even if the subsequent matching algorithm is ingenious, it will be useless.
搜索引擎的使用已经成为排在电子邮件之后的互联网第二大应用工具。人们使用搜索引擎搜索信息,有 1/3 多是在搜索商业信息,搜索引擎在网络营销中正发挥显著的作用,使用它可以有效降低企业推广费用,提高宣传企业产品和服务的效率。
The use of search engines has become the second Internet application tool after e-mail. People use search engines to search information, more than 1/3 is searching for business information. Search engines are playing a significant role in network marketing. Using it can effectively reduce the cost of enterprise promotion and improve the efficiency of marketing products and services.
首先,爬虫本身是无法区分内容优质与否的,搜索引擎的爬虫指标是完成一次全网扫描的时间。然后抓回来的数据进行去重(也有的搜索引擎在爬虫任务分配阶段就完成了去重的工作),去重后的数据要批量导入分布式文件系统,和NOSQL数据库,而不是放在平时说的数据库中,而且爬虫抓回来的数据也不是写入这么简单,还有一个消息队列的过程,对应的开源体系中的KAFKA的功能。再往后才是利用分布式计算,对数据进行权重计算,这时涉及到一项复杂的技术。
First, the crawler itself is unable to distinguish the content from the high quality. The crawler index of the search engine is the time to complete the whole network scanning. Then the data that comes back is weighed (and some search engines have done a heavy job in the phase of the crawling task assignment). The post - weight data will be imported into the distributed file system, and the NOSQL database, rather than in the usual database, and the crawler grabs the data that is not written so simple. There is also a process of message queuing, which corresponds to the function of KAFKA in the open source system. Later, we use distributed computing to calculate the weight of data, which involves a complex technology.
目前国内主流搜索引擎有百度占比80.02%,谷歌:10.81%,搜狗5.75%,其他搜索引擎3.42%,百度是服务于浏览客户的,信息的点击量不是越高,排名越高,而是客户看你这条信息看的时间越久,那么你这条信息就会被百度认为有质量,是客户需要的,这样就可以提升这条信息的排名、和权重;Google使用我们的搜索历程和社交活动,使搜索结果个性化已经多年了,但是这也仅限于Google相关产品中的活动。
At present, the mainstream search engine in China has Baidu 80.02%, Google: 10.81%, Sogou 5.75%, other search engines 3.42%, Baidu is service to browse customers, the amount of information is not higher, the higher the ranking, but the longer the time the customer looks at your information, then the information will be considered to be of quality by Baidu. It is what the customer needs to improve the ranking, and the weight of the information; Google uses our search and social activities to personalize the search results for many years, but this is limited to activities in Google related products.
我们今天所习惯的动态搜索引擎将在未来发生重大变化,未来是只关注「在线」和「离线」来理解用户行为,也许未来的优化与网际网络根本没有任何关系,而是持续优化用户体验,帮助他们的任何有关行为,但这将会影响到一切。http://www.weidaoshang.cn 
The dynamic search engines we are used to today are going to change dramatically in the future. The future is to focus on "online" and "offline" to understand user behavior. Perhaps future optimization has nothing to do with the Internet. It will continue to optimize the user experience and help them with any related behavior, but this will affect it. Everything. Http://www.weidaoshang.cn
