Abstract

The invention relates to the technical field of bidding procurement management, and provides a structured data acquisition method and device based on unstructured bidding document content, which are used for solving the problem of conversion of unstructured data. The invention provides the structured data acquisition method based on unstructured bidding file content. The structured data acquisition method comprises the following steps: acquiring an image of a bidding file; segmenting the image into a plurality of sub-images; and adopting a neural network model to perform feature extraction onthe plurality of sub-images, analyzing the extracted features to obtain target information, and the target information comprises financial information, qualification information and performance information. And the efficiency of converting the unstructured data into the structured data is improved.

Description

technical field [0001] The invention relates to the technical field of bidding procurement management, in particular to a structured data acquisition method based on the contents of unstructured bidding documents. Background technique [0002] In accordance with the overall requirements of Guangdianqi [2019] No. 8 "Notice on Printing and Distributing the Company's Deepening of the Bidding Management Reform Task Decomposition Table", through the use of supplier data reconstruction and other technologies to achieve objective intelligent calculation, automatic positioning of bidding documents, and intelligent auxiliary verification , to reduce the workload of objective and sub-evaluation of experts during bid evaluation, reduce the content of mechanical work of experts, and verify the authenticity of the information provided in bidding documents. [0003] After the bidding documents are collected, most of them are currently stored in the form of unstructured data, such as elect...
