Enterprise development forecast analysis under environmental policy based on knowledge graph

Abstract

Abstract In order to fully explore the relationship between environmental policy and enterprise development, and further improve the forecasting effect of environmental enterprise development, this paper proposes a method of forecasting enterprise development status under environmental policy based on knowledge graph. This method extracts environmental policies and corporate information from the public website of the environmental department to build an environmental corporate knowledge graph, combines cosine similarity and regression algorithms to establish a prediction model for environmental policies and corporate development, and uses the model to analyse environmental policies and predict corporate future development. Experiments show that this method makes full use of the advantages of knowledge graphs in relation analysis and graphical display, has good accuracy and recall, greatly reduces the time cost of enterprise forecasting, and has strong application value.
