Problems solved by technology

[0002] In order to display corporate culture, products, introductions, contact information and other information on corporate official websites, links to key information are usually displayed at the top or left of the page in the form of a navigation bar. In order to accurately establish a content index for corporate official websites, it is necessary to Extract the navigation bar information, but it is difficult to extract the navigation bar due to the freedom of the HTML language used to write the web page and the non-standard code writing.
[0003] The existing technology uses the NAV tag method, but this method requires the page to use the HTML5 version and the developer strictly follows the development manual specification to accurately extract the navigation bar node information
Therefore, for non-HTML5 pages, or irregular code writing, etc., the accuracy of the extracted navigation bar node information is not high, or even impossible to extract

Abstract

The invention relates to the technical field of text extraction. The invention provides a website navigation bar information extraction method and device, electronic equipment and a storage medium, and the method comprises the steps: downloading source codes of a main page and any subpage of a to-be-extracted enterprise website domain name, obtaining a first HTML code, analyzing the first HTML code into a first node DOM tree, and obtaining a second HTML code, and analyzing the second HTML code into a second node DOM tree; removing outer links of the first node DOM tree and the second node DOMtree to obtain a third node DOM tree and a fourth node DOM tree; extracting navigation bar information by using an NAV tag method, an A tag density method, a maximum public area method and a keyword link block method, then performing duplicate removal and filtering, calculating a node score of each node, and outputting the navigation bar information of the enterprise to be extracted. According tothe method, the navigation bar information is extracted through the NAV tag method, the A tag density method, the maximum public area method and the keyword link block method, so that the accuracy andthe efficiency of extracting the navigation bar information in the page are improved.
