Content filtering scientific and technological achievement recommendation method and model and storage medium

Abstract

The invention provides a content filtering scientific and technological achievement recommendation method and model and a storage medium, and the method comprises the following steps: obtaining text data of scientific and technological service demands of a target user and text data of matched scientific and technological achievements, and forming a scientific and technological service data set; performing word segmentation processing on the text data in the science and technology service data set, and then merging to form a total corpus; performing word vector training on the total corpus to obtain a total word vector library; extracting keywords of the text data of each science and technology service demand and the text data of the science and technology achievements in the science and technology service data set; screening a scientific and technological achievement keyword vector library and a scientific and technological service demand keyword vector library from the total word vector library through the keywords; calculating an average word vector of each scientific and technological service demand and scientific and technological achievement; calculating the matching degree between each scientific and technological service demand and all scientific and technological achievements; and screening out scientific and technological achievement information with high matching degree corresponding to each scientific and technological service demand and outputting the scientific and technological achievement information. The scientific and technological achievements meeting the requirements are recommended for the scientific and technological service requirements.

AI Technical Summary

Problems solved by technology

[0006] Collaborative filtering recommendation algorithms are widely used in various fields, but currently there are few feedback information such as user ratings and evaluations in technology service platforms, and there is a problem of data sparsity, and collaborative filtering relies solely on ratings for calculation, which cannot guarantee recommendation accuracy

Traditional content filtering algorithms are often applied to structured data, and have limited semantic understanding of unstructured text information
