Abstract

The embodiment of the invention discloses a web page similarity calculation method and a web page similarity calculation device, which are applied to the field of a computer network and can solve the problem of inaccurate judgment during the similarity comparison of two web pages in the prior art. The method comprises the following steps that: a first blocking feature vector which corresponds to web pages to be tested and is based on a visual structure is generated, wherein the first blocking feature vector comprises a first blocking position feature vector and a first blocking content feature vector; and the first blocking feature vector is compared with a second blocking feature vector which corresponds to a preset web page and is based on the visual structure, and the similarity of the web pages to be tested is obtained. The method and the device provided by the embodiment of the invention are applied to the similarity comparison of the web pages.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to a method and device for calculating similarity of webpages. Background technique [0002] At first, webpage similarity refers to the percentage of the code bytes in the same part of the two webpages in the total bytes of the two webpages. Through similarity comparison, pages can be filtered by content. Reducing webpage similarity is an important aspect of website optimization. important step. With the development of Internet technology and the emergence of new detection requirements, the calculation of web page similarity is not limited to bytecode comparison. Since the development of web2.0, the development of web pages has turned to the degree of clear distinction between front-end and back-end. The front-end focuses on the display form of page content, which is implemented on the browser side through scripts and layouts, while the back-end focuses on business logic and provid...
