Application of deep learning and BP neural network sorting algorithm in financial news network communication

The reasonable ranking of web pages is an important step in the realization of search engine technology, and plays a key role in improving the information quality of high retrieval and presentation web pages. In this paper, the authors analyze the application of deep learning and BP neural network sorting algorithm in financial news network communication. According to the historical data of users in the process of searching and browsing, we can extract the potential connection between the information of the page itself and the user's behavior habits, so as to mine the user's potential preference page. Finally, we use a variety of technologies to mix recommendation and sorting. By observing the effect of multiple training, it is found that the convergence speed of the network model is fast, the training time is short and the training effect is good. We need to fully understand the characteristics of financial news communication in the new media era, and then fully grasp people's financial news reading habits on this basis, and then put forward the innovative mode of financial news communication in the new media era on the basis of these two points.
