Abstract

The invention discloses a bidding file similarity calculation method and device. The method comprises the steps of obtaining effective text information of a first bidding file and effective text information of a second bidding file; searching paragraphs with the same paragraph semantics as the Nth page of the effective text information of the first bidding file from the (N-a)th page to the (N+b)thpage of the effective text information of the second bidding file according to a preset same word search algorithm; determining the same number of words of the effective text information of the firstbidding file and the effective text information of the second bidding file according to the searched paragraphs with the same semantics; and determining the similarity between the first bidding fileand the second bidding file according to the same word number. According to the method, the efficiency and the accuracy of discovering the surrounding label string are greatly improved, and the laborcost and the expandability cost can be greatly reduced.

Description

technical field [0001] The invention relates to the field of natural language processing, in particular to a method and device for calculating the similarity of bidding documents. Background technique [0002] At present, suppliers may engage in bid rigging for profit during bidding, which greatly damages the interests of bidders. The bidding document is essentially a text chapter, which is based on the bidding document template released by the tendering party and then adds the corresponding bidding content of the enterprise.
