Problems solved by technology

[0003] The purpose of the present invention is to solve the current web page information collection method that uses dictionary-type and format-differentiated collection methods. The amount of data that can be subdivided and collected is very limited, the efficiency is low, the accuracy rate is low, the construction cost is high, and the applicable range is narrow. and other problems, inventing a method of artificial fine-grained web page information collection that can intelligently simulate the collection method of manual work

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] As shown in Figures 1, 2, and 3.

[0025] A method for collecting artificially fine-grained webpage information, comprising the following steps:

[0026] a. Use the roaming method of traditional network robots to collect well-structured or semi-structured web content and their URLs on the Internet;

[0027] b. Distinguish templates of URLs (i.e. webpage addresses) of collected webpages, use the part before the symbol "?" The identification mark (some webpages that use post or cookie to pass parameters);

[0028] c. Manually collect the information elements required for one or more purposes in the content of the above-mentioned webpage, and at the same time put them into the local database together with the aforementioned identification marks of this webpage; the information elements mentioned here refer to fine-grained collection information, ...

Abstract

The invention relates to a simulated granule page information collecting method which can simulate the manual collecting method, and solve the problems of present word-type and format-type that used to collect the information of page with lower efficiency and high cost, etc. wherein, it can widely used in building search engine, commercial information collection, and electric website information search. Compared to the rough granule full-text information collected by the traditional network robot, the invention can improve the value of fined collected information, which said information can be directly used to analyze commercial information, the database of similar website, etc.

Description

technical field [0001] The invention relates to a network information collection method that can be widely used to establish a fine-grained query search engine, in particular to a method for artificially imitating fine-grained web page information collection. Background technique [0002] At present, related technologies at home and abroad include two types of methods: dictionary-type analysis and collection, and format-differentiated collection. Among them, the applicable area of ​​format-differentiated collection is very narrow, and the amount of data that can be subdivided and collected is very limited (such as the title of an article in a web page, The title in the country page, etc.), is rarely used at home and abroad. At present, the method of dictionary analysis is mostly used, such as: *company; *university; *hospital; *yuan. This method has many disadvantages such as low efficiency, low accuracy, high construction cost, and narrow application. Using this method to ...
