Abstract

The present application provides a method and system for checking the execution report of pollution discharge license, which collects multi-format electronic execution reports, converts unstructured data into structured data through OCR recognition, and unifies the format, standardizes the units, marks the missing values, and removes the duplicates. A four-dimensional checking system including the integrity of basic information, data specification, logical consistency and compliance is constructed, and rules are set according to national standards and industry threshold values. The data specification is checked by keyword matching, the logical consistency of information related to the permitted discharge amount is verified by formula engine, and a cross-source cross-validation model is established by combining the environmental management account and self-monitoring data of the pollution discharge unit to identify hidden abnormalities. For the abnormal data information identified in the execution report, a decision tree algorithm is used for intelligent tracing and hierarchical judgment, the reasons are sorted according to priority, a standardized checking report is generated, and feedback is given to the pollution discharge unit and the supervisory department.
