Method and system for risk control before project investment

The invention provides an recognition method and system before project investment. The method comprises the steps of acquiring project main body data, acquiring project ontology data, performing datapreprocessing on the project main body data and the project ontology data to generate a dynamic portrait, and digitally displaying the project main body dynamic portrait and a dynamic user portrait ofa project ontology. The project main body portrait and the project body portrait are strictly independent. Therefore, the operation capability of the project main body and the development prospect ofthe project main body can be checked dynamically in real time. And finally, objective and rational investment judgment is made through comprehensive comparative analysis, so that the problems of highproject risk and investment income damage caused by insufficient risk recognition in the early stage of project investment, inadequate risk prevention in the middle stage and inadequate risk decentralized solution measures in t
