Method and related device for evaluating web page publishing time

Abstract

An embodiment of the invention discloses a method for evaluating web page publishing time and a related device. The method for evaluating the web page publishing time comprises the steps of recognizing N time character strings in a web page; respectively extracting M reference features of each of the N time character strings; respectively grading the M reference features of each of the N time character strings according to the preset grading rules, obtaining the total point of the M reference features of each of the N time character strings, and enabling the time described by the corresponding time character string with the total point meeting the preset grading condition to serve as the web page publishing time. According to the technical scheme, the method for evaluating the web page publishing time is favorable for improving the evaluating accuracy of the publishing time of the web page main content.

Description

technical field [0001] The invention relates to the field of the Internet, and in particular mainly relates to a method and a related device for evaluating the publishing time of a web page. Background technique [0002] The response header of the Hypertext Transfer Protocol (HTTP, Hypertext transfer protocol) protocol usually contains the last modification time (Last-Modified time) of the web page, and search engines usually extract the time from the HTTP response header when crawling the page. Value as page publish time. [0003] The inventor of the present invention found in the process of research and practice that at least the following technical problems exist in the prior art: the last modification time of a web page often cannot accurately reflect the real publishing time of the page. For example, when an editor modifies a web page (such as adding advertisement information), the last modification time changes. At this time, the release time of the main information ...

Problems solved by technology

[0003] The inventors of the present invention have found in the course of research and practice that at least the following technical problems exist in the prior art: the last modification time of a web page often cannot accurately reflect the real release time of the page

For example, a webpage describing "2008 Beijing Olympic Games", but the editor made revisions to the webpage in 2012, and the last modification time was changed to 2012, which is inconsistent with the real release time of the main body of the webpage

Also, not all pages have a last modified time

Therefore, it is not appropriate to directly use the last modification time of the webpage as the publishing time of the webpage in many scenarios
