Problems solved by technology
[0012] The technical problem to be solved by the present invention is how to provide a method for risk assessment using unstructured data, so as to solve the problem of financial risk early warning based on structured data. The information brought by the structured data, the information of the enterprise to be evaluated is not comprehensive, so it is difficult to accurately evaluate the cooperation risk of the enterprise, and there are defects in the risk warning

Embodiment Construction
[0053] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0054] The purpose of the present invention is to propose a method for risk early warning using unstructured data. The method comprises the steps of:
[0055] S1. Data collection
[0056]Firstly, select the data source for collection, and secondly, during the collection process, use scrapy technology to collect data from the Internet, use the name of the enterprise to be evaluated and common aliases to filter the information, and then select the relevant information containing the enterprise to be evaluated to collect one by one, including News titles / texts, judgment documents and comment information; finally, store the collected data in the mysql database;
[0057] S2. Data cleaning
[0058] The collected Internet d...

The invention relates to a method for performing risk assessment by using unstructured data, and belongs to the field of artificial intelligence. According to the method, the enterprise cooperation risk is assessed by utilizing the Internet news data and the comment data, so that the risk caused by only reviewing enterprise qualification and implementation capability and neglecting information such as enterprise wind assessment is avoided; and the enterprise cooperation risk is assessed by using the real-time performance of Internet data, so that the enterprise cooperation risk caused by old information is avoided. Compared with the prior art, the technical scheme provided by the invention adopts the unstructured data to carry out risk assessment on the enterprise cooperation relationship. According to the method, news data, comment data and judgment document data related to an enterprise to be assessed on the Internet are collected, and enterprise risk assessment scoring is comprehensively carried out. According to the method, the information which should be concerned before enterprise cooperation is effectively supplemented, and meanwhile, the real-time performance of the enterprise information to be evaluated is ensured.
Description
technical field [0001] The invention belongs to the field of artificial intelligence, and in particular relates to a method for risk assessment using unstructured data. Background technique [0002] When conducting cooperation between enterprises, it is usually necessary to conduct a risk assessment on the partner enterprise to confirm whether the cooperation will bring economic risks. The current method of risk assessment for cooperative enterprises, in addition to manual review, is mainly based on structured data for risk assessment of partners. [0003] The approach to risk early warning using structured data usually consists of the following steps: [0004] Data integration and cleaning. Integrate structured data from different sources, and perform necessary cleaning and transformation on the data according to the data quality. [0005] feature selection. According to the business knowledge, the characteristic data items that are beneficial to the effect of risk warn...
