Subject characteristic value algorithm and subject characteristic value algorithm-based project evaluation expert recommendation algorithm

Abstract

The invention provides a subject characteristic value algorithm and a subject characteristic value algorithm-based project evaluation expert recommendation algorithm. The subject characteristic value algorithm-based project evaluation expert recommendation algorithm comprises the following steps: (1) carrying out text similarity calculation: 1) carrying out word segmentation on text information of the project study content and evaluation expert research direction, 2) carrying out establishment of a text characteristic vector model of the project study content and evaluation expert research direction, and 3) carrying out similarity calculation on the text characteristic vector of the project study content and evaluation expert research direction; (2) carrying out the subject characteristic value algorithm; (3) carrying out calculation on the project evaluation expert recommendation value, wherein the calculation formula is as follows: ProSim(V, U)=w(c) x exp[sim(V,U)]; (4) sequencing the project evaluation expert recommendation values obtained by calculation in the step (3). The subject characteristic value algorithm and the subject characteristic value algorithm-based project evaluation expert recommendation algorithm disclosed by the invention has the advantages that under the condition of no artificial interference, a processing program which applies the project evaluation expert recommendation algorithm can automatically calculate scientific research projects and recommendation values of different evaluation experts, and user time is saved.

Description

technical field [0001] The invention relates to the field of recommendation algorithms, in particular to a discipline characteristic value algorithm and a project review expert recommendation algorithm based on it, which is used to automatically complete the recommendation work of scientific research project review experts by using a computer. Background technique [0002] An effective scientific research project is the most basic condition for the organization and implementation of my country's science and technology development, and it is a powerful guarantee related to the development of my country's science and technology strategy. At present, for the evaluation of scientific and technological projects, the most critical thing is the selection of evaluation experts. The so-called "finding the right person to do the right thing" cannot be achieved in the selection of evaluation experts. The reason is that there is no unified automatic selection model at present, and it st...

Problems solved by technology

[0005] However, these recommendation algorithms above are basically born based on the commercial recommendation algorithm model, basically based on the two-dimensional space measurement of "user-target", such as the algorithm based on the project research content and the research direction of review experts, which extract key The word calculates the similarity of the text feature vector, thus ignoring other relevant information
