What is a reptile?

Web crawler (also known as web spider and web robot) is a program that simulates a browser to send network requests and receive request responses, and automatically crawls Internet information according to certain rules.

In principle, a crawler can do anything that a browser (client) can do.

Why do we use reptiles?

In the era of big data on the Internet, we have been given the convenience of life, and massive data in the network has exploded.

In the past, we got information through books, newspapers, television and radio. The amount of information is limited, which is relatively effective after certain screening, but the disadvantage is that the amount of information is too narrow. Information transmission is asymmetric, so that our vision is limited and we cannot learn more information and knowledge.

In the era of big data on the Internet, all of a sudden, we can get information freely. We get a huge amount of information, but most of it is invalid junk information.

For example, Sina Weibo generates hundreds of millions of status updates a day, but in Baidu search engine, you can randomly search for one-100.000.000 pieces of information about losing weight.

Through certain technology to collect relevant content, after analysis and deletion, we can get the really needed information.

This kind of information collection, analysis and integration can be applied to a wide range of fields, whether it is life service, travel, financial investment, or product market demand of various manufacturing industries, etc ... They can use this technology to obtain more accurate and effective information.

Although the name of web crawler technology is strange, the first reaction is that soft reptile is a weapon that can be improved in virtual world.
