Method and device based on urban rail project demand identification and coverage

Abstract

The invention discloses a method and device based on urban rail project demand identification and coverage, relates to the technical field of urban rail projects, and aims to automatically identify general technical demands in a project demand matrix from a typical demand matrix and automatically cover some project demand information in the project demand matrix so as to liberate repeated requirements to a great extent to cover manual work. According to the main technical scheme, the method comprises the steps of reading a project demand matrix and a typical demand matrix, wherein the projectdemand matrix comprises one or more pieces of project demand information, and the typical demand matrix comprises one or more pieces of feature demand information; performing semantic similarity calculation by comparing the project demand information with the feature demand information; if it is judged that the semantic similarity obtained through calculation reaches a preset threshold value, marking the feature demand information as a typical demand capable of being covered; and filling a typical demand record corresponding to the project demand information with the coverable typical demand.

Description

technical field [0001] The invention relates to the technical field of urban rail projects, in particular to a method and device based on identification and coverage of urban rail project requirements. Background technique [0002] In recent years, the construction of my country's urban rail transit (hereinafter referred to as "urban rail") has ushered in a period of rapid development in the industry. When implementing urban rail projects, although the locations, regions, and station types are different, the basic signal technology used is common. , so the requirements of each urban rail project have a large degree of similarity. [0003] At the present stage, during the implementation of urban rail projects, the extraction, coverage and verification of project requirements are mostly handled manually, and because the requirements of urban rail projects will have a large degree of similarity, then for different urban rail projects, there will also be There are a lot of repet...

Problems solved by technology

[0003] At the present stage, during the implementation of urban rail projects, the extraction, coverage and verification of project requirements are mostly handled manually, and because the requirements of urban rail projects will have a large degree of similarity, then for different urban rail projects, there will also be There are a lot of repetitive requirements work, which leads to low efficiency of project requirements extraction, coverage and verification. Manually facing a large number of requirements is prone to errors, which also has a negative impact on subsequent project implementation.
