Problems solved by technology

However, its knowledge base construction and labeling system are only applicable to the bond industry, and cannot be directly dedicated to the futures industry
[0004] Public opinion information in the futures market has the characteristics of rapid diffusion, difficulty in discovery, wide influence, and complex transmission chain. However, the existing public opinion analysis technology mainly uses methods such as statistical analysis of keywords and construction of a public opinion labeling system to discover hotspots and summarize public opinion. Public opinion analysis such as intelligent public opinion analysis has limitations
