Example Embodiment

[0025] Such as Figure 1-4 As shown, this specific implementation adopts the following technical solution: a method based on the matching degree between text semantic analysis requirements and output results, including the following steps:

[0026] A method based on text semantic analysis of the matching degree between requirements and output results, including the following steps:

[0027] Step 1. Data set annotation: Use text information based on project requirements description, achievement description and project title to compare and summarize the correlation and matching degree of the two projects and perform four-category annotation to construct a labeled data set for project matching calculation modeling ;

[0028] Step 2. Technical document preprocessing: Construct the Bert model input text. In view of the limitation of the Bert model input sequence length and computing resources, the Rough-L algorithm is used here based on the project name to core the project requirements an...

Abstract

The invention discloses a method for analyzing a matching degree between a demand and an output result based on text semantics. The method comprises the following steps: step 1, labeling a data set; step 2, technical document preprocessing; 3, training and predicting a single-parameter model; 4, integrating prediction results of the multi-parameter model; the method has the beneficial effects thatthe method is simple; deep learning and the NLP technology are applied to the field of project association degree calculation of enterprise project management for the first time. Calculating an association matching degree between the two projects according to project requirements and result description; the associated project positioning difficulty is effectively reduced; meanwhile, the demand side can be helped to quickly and efficiently locate high-quality projects adapting to the demand of the demand side; time and resource investment for achievement screening and matching are greatly reduced, the association matching degree between projects is calculated by means of text data of existing project achievement technical documents and project declaration guidelines, and then large enterprises are assisted in screening high-quality projects with the high matching degree in the project bidding and tendering link.

Description

Technical field: [0001] The invention belongs to the field of calculating the matching degree between project requirements and results in an unrestricted industry, and in particular relates to a method for analyzing the matching degree between requirements and output results based on text semantics. Background technique: [0002] The calculation of project relevance is one of the important links in enterprise project management, especially for state-owned enterprises like power grids, which have a large number of existing project achievements and a huge number of project applications each year. How to calculate the correlation between the existing pre-research projects and the projects to be declared in the application guidelines for scientific and technological projects, clarify the matching relationship between the projects, and retrieve the most suitable needs among the many pre-research projects according to the specific research topics in the application guidelines Bidd...
