The embodiment of the invention discloses a digital television interaction service page information extraction method and a digital television interaction service page information extraction device. The method comprises the following steps of: acquiring web pages, and remaking the web pages to obtain extensible hypertext markup language (XHTML) documents; establishing a document object model (DOM) tree according to the XHTML documents; clustering the acquired web pages according to the DOM tree; acquiring a web page template corresponding to the clustered web pages of the same cluster; and performing information extraction according to the web page template, and acquiring extracted detailed information. By the digital television interaction service page information extraction method and the digital television interaction service page information extraction device provided by the embodiment of the invention, the digital television interaction service page key information acquisition speed can be increased, and the digital television interaction service page information data processing load also can be reduced.
Description
technical field [0001] The invention relates to the technical field of digital television, in particular to an information extraction method and device for a digital television interactive service page. Background technique [0002] With the rapid development of the Internet (Internet) and digital television, interactive service pages have become a huge and complex information warehouse. How to quickly extract information from massive interactive service pages and improve the efficiency of people's access to information is becoming more and more important. At present, the vast majority of interactive service pages are dynamic web pages, which are usually composed of the background database of the website through some common template, and have very similar page structures, such as search results returned by search engines, product information in online stores Pages, etc. are typical dynamic web pages. The number of such webpages is often huge and rich in content, so the ext...
