Abstract

The invention provides a Yellow River basin evolution analysis method based on text mining. The Yellow River basin evolution analysis method comprises the steps of S1, obtaining an analysis sample corresponding to Yellow River basin evolution; s2, constructing a corresponding knowledge element co-occurrence network; s3, constructing a quotation coupling network, and constructing a knowledge element fusion network based on the quotation coupling network and the knowledge element co-occurrence network; s4, analyzing the constructed target knowledge element network corresponding to different time slices to obtain an evolution analysis path of the Yellow River basin; s5, obtaining a corresponding evolution analysis result based on the evolution analysis path and a co-occurrence cluster of each target knowledge element and each core knowledge element in the target knowledge element network; the method is used for meeting the analysis accuracy, instantaneity and intersectionality of literatures in each field in the evolution analysis process of the Yellow River field, rapidly and accurately tracking the development trend of the Yellow River basin in each field, and mastering the evolution rule of related knowledge, so that technical support is better provided for applying measures to the Yellow River basin according to local conditions and classified measures.

Description

technical field [0001] The invention relates to the technical field of text mining, evolution analysis and cross-domain analysis and fusion, in particular to a method for analyzing the evolution of the Yellow River Basin based on text mining. Background technique [0002] At present, the ecological protection and high-quality development of the Yellow River Basin has become a national strategy, and the research hotspots and frontier trends in the basin have received increasing attention. Identifying and monitoring the evolution and migration of academic research and policy research in the Yellow River Basin is conducive to grasping the flow law of the development of the Yellow River Basin, tracing the development trajectory of the Yellow River Basin in academic and policy aspects, and providing effective selection and tracking of key research projects. Learn and reference. Therefore, it is necessary to analyze and classify the number of articles published, institutions, aut...
