Embodiment

[0032] A method for classifying webpages in this embodiment includes a data collection layer, a webpage parsing layer, and an application presentation layer sequentially from bottom to top according to the data flow direction, such as figure 1 shown, including the following specific steps:

[0033] (1) Read the URL list of the preset URL navigation site, which stores many navigation URLs, such as www.hao123.com, www.sohu.com, etc.;

[0034] (2) Judging whether the URL list is empty, if empty, it means that the search has been completed, go to step 8 and end, if not empty, then continue to step 3;

[0035] (3) Take out a URL;

[0036] (4) Query the URL in the V_URL list of the visited URL storage table. V_URL stores all URL addresses that have been visited. If the URL is found in V_URL, it means that it has been visited. Then go to step 3, if not If it is found, it means that it has not been visited, then continue to step 5;

[0037] (5) Use the focused crawler technology to...

Abstract

The invention discloses a method for webpage classification. The invention comprises a data acquisition layer, a webpage analysis layer and an application representation layer from down to up in sequence according to the data flow direction, wherein the data acquisition layer acquires source codes of all webpages preset in a navigation website address list by using a focused crawling technology, the webpage analysis layer extracts structural information to the webpages meeting webpage specific structural characteristics, extracts the lower-layer linkage meeting the requirement and enables the information of the lower-layer linkage conforming to the search strategy to be added in a website address categories list and the application representation layer can obtain webpage classification information of an unknown URL according to the website address categories list. The invention not only has the search breadth of universal search, but also has the search depth of vertical search and also can conveniently obtain the webpage classification information of an unknown URL in the classification website.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method for classifying webpages. Background technique [0002] With the continuous expansion of network information, people are increasingly inseparable from search engines. Although general search engines such as Baidu and Google provide people with a lot of convenience, they also have certain limitations, such as: the results returned by general search engines include a large number of webpages that users do not care about, and the search depth is not enough. [0003] As a result, vertical search came into being. It is an accurate search technology serving a certain industry field. It is a subdivision and extension of search engines. Provide queries based on semantic information, so as to meet the special search needs of users. However, most of the current vertical searches are for a specific industry and a specific field, and it is impossible to conduct vertical searches ...
