With the development of the national economy, China's listed companies have increased year by year. The company's annual report, brokerage research report and even the comments in the stock market will become an important basis for reflecting the operation of the listed company. This paper first summarizes current technology related to corporate portrait in the world, and on the basis of predecessors, innovatively proposes multi-dimensional corporate portrait analysis and builds a corporate image system based on big data platform. The portrait system includes three dimensions: financial aspect, research report aspect and public opinion aspect. The level of technology is combined with popular classification labels, word cloud maps and Bidirectional GRU algorithms, etc. This paper uses the listed company BOE to give an example.
