Problems solved by technology

[0003] Because the stock market is easily affected by many factors, it is very difficult to predict stocks. Existing stock prediction methods include fundamental analysis, technical analysis, and time series analysis, etc., which cannot grasp financial investment information in a timely manner. The analysis and prediction of stock data Both efficiency and accuracy need to be improved, and the user experience is not good

Abstract

The invention discloses a data analysis and prediction method and device, and relates to the technical field of big data, and the method comprises the steps: building a financial news data set; performing unsupervised corpus pre-training on the financial news data set by adopting a BERT model to obtain a pre-training model; performing binary classification training with supervised training on the pre-training model by using the financial news data of which the data labels are established according to the return rate of the stock corresponding to each piece of financial news data to obtain a news sentiment classification model; inputting the target financial news data into a news sentiment classification model to obtain a sentiment index; establishing a stock sample data set corresponding to the financial news data set, and constructing an LSTM model for predicting a stock trend; inputting target stock data corresponding to the target financial news data into the LSTM model to obtain a trend prediction value; analyzing and predicting the target stock according to the trend prediction value and the emotion index, thus the efficiency and accuracy of stock data analysis and prediction can be improved, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of big data, in particular to a method and device for data analysis and prediction. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] Because the stock market is easily affected by many factors, it is very difficult to predict stocks. Existing stock prediction methods include fundamental analysis, technical analysis, and time series analysis, etc., which cannot grasp financial investment information in a timely manner. The analysis and prediction of stock data Both efficiency and accuracy need to be improved, and the user experience is not good. [0004] Therefore, how to provide a new solution that can solve the above technical problems is a technical problem to be solved urgently in this field. Con...
