Research On The Correlation Between Financial News And Stock Index Based On Artificial Intelligence

With the rapid development of the Internet and the rise of artificial intelligence in recent years,especially the large-scale application of its branch natural language processing technology,financial practitioners can use a large amount of financial news to predict and analyze stock market fluctuations.In this context,it is of great significance to use new technologies related to artificial intelligence to analyze the relationship between financial news and stock price trend.This paper empirically uses AI related technologies and tools to quantify the financial news,and with the help of AI related algorithms,through the quantified financial news to predict the rise and fall of the stock index,so as to reveal the hidden law between the financial news and the stock market,so as to help investors make better decisions.This paper uses the rise and fall of stock index to mark the relevant news text data.Mark four groups of data and set up four groups of independent experiments.The data set is divided into test set and training set.The training set is used to train the artificial intelligence model,which is verified on the verification set respectively to obtain the relevant experimental data.Then,according to the experimental data,analyze the correlation between the English news of the day and the rise and fall of the Dow Jones index on the day and the next day,and the correlation between the Chinese news of the day and the rise and fall of the Shanghai Composite Index on the day and the next day.According to the analysis results,the accuracy of financial news in predicting the rise and fall of stock index is high,which proves that there is a strong correlation between financial news and the rise and fall of stock index,and the correlation between financial news and the rise and fall of stock index is not consistent.Moreover,the experimental conclusion shows that the stock index has an obvious lag in response to financial news,and the rise and fall of stock index is more sensitive to the news response of the previous day.This paper has a strong influence on the theoretical and practical research results of the media,and can have a strong impact on the research results of the financial market.
