Problems solved by technology

[0006] However, the current probabilistic topic model has relatively low computational efficiency and low accuracy. The discovered topics may contain meaningless topics such as background, and the interpretability of topic descriptions is not strong, so it is difficult to carry out optimize and utilize

Abstract

The embodiment of the invention provides a scientific research hotspot theme analysis method and device and electronic equipment, and the method comprises the steps of building a citation network based on scientific research literatures, and calculating the literature sorting weight of each document through a random walk algorithm, so as to filter the literatures, and obtain citation data and a corpus; and evaluating and screening the obtained citation data and corpus based on a probability topic hierarchical combination model to obtain a hotspot scientific research theme. According to the embodiment of the invention, the theme evolution diagram is constructed according to the literature structure information and the theme affiliation information, and theme description optimization, themesorting and theme evolution are combined through the theme evolution diagram, so that a more accurate result is obtained on the premise of improving the time efficiency.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of topic mining of scientific research documents, and more specifically, relate to a method, device and electronic equipment for analyzing hot scientific research topics. Background technique [0002] In scientific research analysis work, effectively discovering hot research topics and the development and changes of hot topics from massive literature information is gradually becoming a concern of current scientific research management departments and scientific research workers. [0003] In the traditional scientific research data analysis method, the machine learning method of probabilistic topic model is introduced. The use of this model provides a new research idea for researchers engaged in scientific research data analysis. At the same time, from the perspective of individual researchers, keeping abreast of the hot spots in their research fields and the degree of fit with their own...
