Cadmium-related enterprise directory construction system and construction method based on industry difference

Abstract

The invention relates to a cadmium-related enterprise name list construction system and construction method based on industry difference. The system comprises a cadmium-related industry type determination module, a crawling module, a supplementing module, an integration cleaning module and a cadmium-related industry enterprise name list forming module. The cadmium-related industry type determination module is used for determining a specific cadmium-related industry type; the crawling module is used for crawling the public data information of the cadmium-related enterprise and formatting the public data information; the supplementing module is used for crawling to obtain a cadmium-related industry enterprise supplementation list by taking an industrial and commercial enterprise list information website as a supplementation information source and combining the determined cadmium-related industry type and the retrieval keyword; and the cadmium-related enterprise name list forming module is used for achieving data standardization according to a uniformly set data structure, acquiring preliminary longitude and latitude information of a spatial position missing cadmium-related enterprisein combination with an address where the enterprise is located and network map POI information, and performing coordinate system conversion according to a unified spatial information mathematical basis of a project to form a cadmium-related enterprise name list.

Description

technical field [0001] The invention relates to the technical field of information processing of cadmium-related enterprises, in particular to a system and method for constructing a directory of cadmium-related enterprises based on industry differences. Background technique [0002] In the existing technology, the data of enterprises in the cadmium-related industry mainly comes from the active disclosure of the relevant functional departments of the national ecological and environmental protection, and the accuracy and authority of the data are guaranteed to a certain extent. Insufficient in terms of timeliness and completeness, it is difficult to completely avoid under-reporting and under-reporting. For this reason, it is necessary to combine the commercialization of network geographic big data (including the national enterprise credit information publicity system, Qichacha, Tianyancha, Greennet, etc.) information platform) to make comprehensive supplements and third-party ...

[0002] In the existing technology, the data of enterprises in the cadmium-related industry mainly comes from the active disclosure of the relevant functional departments of the national ecological and environmental protection, and the accuracy and authority of the data are guaranteed to a certain extent. Insufficient in terms of timeliness and completeness, it is difficult to completely avoid under-reporting and under-reporting. For this reason, it is necessary to combine the commercialization of network geographic big data (including the national enterprise credit information publicity system, Qichacha, Tianyancha, Greennet, etc.) information platform) to make comprehensive supplements and third-party confirmation of public information of the department, and at the same time combine the POI information of the network map to extract the longitude and latitude information of the missing enterprise in spatial coordinates, realize the spatialization of enterprise information, and establish a more complete and quickly updated national cadmium-related enterprises directory
