YANG Jin-hui1,ZHAO Jin2a,MA Tian-yi2b,SUN Yan-feng1(1.College of Computer Science and Technology,Jilin University,Changchun 130012,China;2a.College of Information;2b.College of Economy,Renmin University of China,Beijing 100872,China)  
In order to overcome the limitation of traditional method and provide a decision making reference for the supervision of securities organizations and the risk control of investors.A novel PCA-SOM(Principal Components Analysis-System Object Model) is proposed for assess of financial performance of the listed companies.In this model,the PCA(Principal Components Analysis) is utilized to establish an assessment model of a company's financial performance.And the SOM(System Object Model) model is used to examine the effectiveness of the proposed model.The experiments are conducted on the financial dataset of 47 listed realty companies to examine the presented model.The simulated results show that the PCA-SOM model performs better,reduces the disturbance of manual factor effectively,appraises the listed companies,provides the currect ranking and offers the reference for the institution.
