Embodiment Construction

[0052] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.

[0053] In this embodiment, the present invention is further described by automatically extracting target object parameter information oriented to the bidding text.

[0054] Bidding business is an important task for enterprises to carry out project management, and bidding documents have relatively standardized writing requirements and text content. Therefore, if the bidding document text is used as corpus for research, the management, application, feedback, and update iteration of standard bidding documents can be realized. These functions can significantly im...

Abstract

The invention discloses a text information automatic extraction method, and aims to solve the problems that parameter information of bid invitation document subject matter in the prior art is extracted manually, a large amount of labor and time are consumed, and time and labor are consumed. The method comprises the steps: automatically extracting parameter information of a bid inviting text through the natural language processing technology, designing a bid document text structuralization, extracting subject matter parameter information and report extraction system, wherein the bid document text structuralization comprises the steps: extracting the bookmark information through a pypdf2, recognizing a pdf bid document text through a pdflumber, and cleaning the text through a regular rule; and performing structured analysis processing on the text by utilizing rule matching. In the subject matter parameter information extraction, the technical parameter information of the subject matter in the structured bidding document text is accurately identified and extracted by using a regularization technology. And finally, an extraction report is established by utilizing the information in theprocess, and the whole extraction condition is visually reflected.

Description

technical field [0001] The invention belongs to the technical field of computers and relates to a method for automatically extracting text information, in particular to a method for automatically extracting object parameter information oriented to bidding texts. Background technique [0002] With the continuous development of intelligence and automation of information technology, it has brought a huge impact and convenience to people's lives. It can automatically convert text into pictures, and can also convert pictures into text, becoming more and more intelligent. , more and more convenient and convenient; but for some specific fields, the required information is specific, and the existing technology is difficult to extract information in a targeted manner, such as the automatic extraction of target parameter information for bidding texts. [0003] Bidding documents are a concentrated expression of procurement needs, and the quality of bidding documents directly determines...
