Embodiment Construction

[0090] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0091] Such as figure 2 A management system for the crawler crawling method shown in the automated vertical subdivision field includes a crawler crawling core layer and a crawler control management layer, which are used for parameter configuration, operation management, and real-time monitoring of the crawler. The management system .

[0092] The crawler crawling core layer is based on the Scrapy crawler application framework. Scrapy uses the Twisted asynchronous network library to process network communication. The structure is clear and includes various middleware interfaces, which can flexibly fulfill various requirements. image 3 It is the algorithm flow chart of the core layer of the crawler.

[0093] The crawler crawling core layer specifically includes the following components:

[0094] Engine: controls the data processing flow of th...

Abstract

The invention relates to the technology of crawler crawling and management scheduling and aims at providing a crawler crawling method in the field of automatic vertical subdivision and a management system. The crawler crawling method in the field of the automatic vertical subdivision comprises the steps of predicting crawler operation time; carrying out batch crawler scheduling optimization according to prediction time and the parallel number; and carrying out crawler crawling. Compared with the prior art, the method and the system have the advantages that the crawling efficiency of crawlers in the field of the automatic vertical subdivision is relatively high; through combination of features of vertical subdivision crawlers, a time prediction model for the crawlers is creatively introduced; and through combination of a longest processing time algorithm, the efficient scheduling of the parallel crawlers is carried out, so the crawling time is reduced.

Description

technical field [0001] The invention relates to the technical field of crawler crawling and management scheduling, in particular to a crawler crawling method and a management system in the field of automatic vertical subdivision. Background technique [0002] Although the information age of the data explosion contains massive amounts of information and data from all walks of life, human beings are limited in the amount of information they can receive and the ability to process information. We are often occupied by a large amount of redundant and useless information. It is becoming more and more difficult to personalize information, so various vertical segments and personalized recommendations emerge as the times require. Vertical segmentation focuses attention and services on a specific category, and data crawling for vertical segmentation is an important and basic work for services such as personalized recommendations. [0003] A web crawler is a program that automatically...
