Detection method and system for bid enclosing and bid stringing and storage medium

Abstract

The invention discloses a detection method and system for bidding and stringing bids and a storage medium, and the method comprises the steps: obtaining the address information of all bidding parties, and copying and storing all address information to an address database; comparing the address information with address information in the address database to obtain a comparison result; and outputting abnormal information according to the comparison result, or obtaining a bidding file of the bidder, performing similarity analysis on the bidding file to obtain a bidding similarity, and comparing the bidding similarity with a preset similarity threshold to obtain a similarity report. Through address information comparison and bid document similarity analysis, bid evaluation efficiency is effectively improved, whether bidding parties have bid surrounding and bid confusion behaviors can be rapidly identified, whether the same compiled bid document is not compiled can be rapidly identified through the address information, and bid evaluation efficiency is improved. And whether different bidding parties are the same or not can be quickly identified through similarity analysis of the bidding files.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a detection method, system and storage medium for tagging and collusion. Background technique [0002] With the development of the economy, the market competition is becoming more and more fierce. When the bidding party conducts bidding, it needs to collect bids from various merchants to determine the merchants to cooperate with according to the content of each bid. However, some merchants engage in bid rigging in order to increase the probability of cooperation. [0003] In order to prevent bid rigging, it is necessary to manually analyze whether the IP of the files uploaded by the bidders is the same, and whether the bidding documents are duplicated, and then analyze whether there is an affiliated enterprise relationship between the bidders, and then determine whether there is bid rigging among the bidders. standard behavior. However, the IP address can...

Problems solved by technology

However, the IP address can also be tampered with through tools, or the IP address obtained after going through multiple layers of agents is inaccurate, and it is impossible to accurately determine whether the bidder has bid-rigging behavior, and the analysis is performed manually, which increases the workload of the staff on the one hand. , on the other hand, it affects the progress of the bidding work
