The present disclosure discloses a method and apparatus for recognizing a text type, and a device. A specific embodiment of the method comprises: preprocessing a pre-acquired text to obtain a keyword set of the text; calculating an occurrence probability value of each keyword in the keyword set in the text; importing, for the each keyword in the keyword set, the keyword and the occurrence probability value corresponding to the keyword into a pre-established document topic generation model, and determining an occurrence probability value of each topic in the text preset in the document topic generation model; and recognizing a type to which the text belongs based on the occurrence probability value of the each topic in the text. The embodiment improves an accuracy of recognizing the type of the text.

The present disclosure provides a method for an authentication system to provide authentication information for a web page, comprising: receiving a request for authentication information from a web page; judging whether the web page is redirected to through a relevant search engine; judging whether the web page satisfies a condition of displaying the authentication information; and providing the authentication information to the web page satisfying the condition. By providing authentication information to a web site through a search engine, with the combination of the authentication system with the relevant search engine, the reliability and security of authentication information are enhanced. Besides, the user may autonomously edit and manage the displaying pattern of the authentication information, such that the authentication information may be displayed in real time on the web page.

Method and device for providing authentication information on web page

The present disclosure provides a method and apparatus for providing website authentication data for a search engine, the method comprising: receiving website authentication data from a plurality of authentication data sources; storing the website authentication data; and transmitting the stored website authentication data to the search engine when a request from the search engine for retrieving the website authentication data is received. By virtue of the method, the search engine may quickly retrieve complete website authentication data, thereby facilitating the search engine's search speed.
