The self-adaptive updating of the inspection rule specifically comprises the following steps: and matching the corresponding inspection rule by the captured keywords through an NLP technology, and periodically synchronizing the inspection rule of the data center of the marketing domain.
The inspection rule is updated regularly, and the version of the marketing inspection rule is upgraded through the function, so that the management of the rule is facilitated. Meanwhile, the historical inspection rule version and the corresponding basic rule detail can be inquired, and a plurality of pieces of information can be combined for inquiry and a list can be exported. And the accuracy of the adjustment of the inspection rule can be monitored and evaluated, so that data support is provided for the perfection of the inspection rule. The inspection rule management function of the inspection system is connected with the data center of the marketing domain to realize the acquisition of the inspection rules, so that the data is synchronized periodically. In addition, the inspection system also supports the introduction of the latest inspection rule in a manual mode, and meanwhile, the operation of adding, deleting and modifying the inspection rule of a certain service class can be realized.
The self-defined combination function of the inspection rules realizes the combination of the inspection rules of different marketing services of the same service type. The combination of different marketing service inspection rules is a problem list meeting the screening and re-checking conditions under various rule conditions after the combination is carried out by a marketing inspection auxiliary system.
S13, on the basis of self-adaptive updating, according to marketing monitoring, abnormal rules and audit risks, adopting an SAE algorithm model to refine audit characteristics, and simultaneously constructing new audit clues to form an automatic updating mechanism of the audit clues so as to ensure the correctness of audit points. Automatically updating the inspection characteristics to the new inspection clues to form a preliminary inspection knowledge map.
S2, applying the preliminary inspection knowledge graph to perform full data cruise on all marketing service information of the marketing domain data center to find marketing service information with suspected inspection problems. And supplementing the preliminary inspection knowledge graph according to the marketing service information with suspected inspection problems.
S2 specifically includes:
and S21, periodically synchronizing the marketing business information of the marketing domain data center. Specifically, marketing business information is synchronized from a marketing domain data center monthly as needed for full audit business. The marketing service information specifically comprises a task number, a task name, a service type, a synchronization date, an operator and a state, and the monitoring and management of the service data synchronization task are facilitated. According to the development need of the inspection service, service data are synchronized from the marketing domain data center to the intelligent accurate inspection system database periodically, and a data source is provided for inspection.
And S22, automatically extracting the synchronized marketing service information through the etl timing task, and checking the data integrity of the extracted marketing service information. Namely, data of the synchronous marketing service information is summarized, and synchronous abnormal data, database table loss and the like are displayed so as to ensure the correctness of source data. And storing the incomplete marketing business information into the auxiliary database, and storing the complete marketing business information into the task database.
The marketing service information is automatically acquired and supplemented, the information is automatically extracted through the etl timing task, and when the marketing service information is abnormal and the data acquisition cannot be completed, the marketing service information can be synchronized into the database of the inspection auxiliary system through the functional operation.
S23, cruising the marketing business information in the task database by applying the preliminary inspection knowledge map to find out the marketing business information with suspected inspection problems. And supplementing the preliminary inspection knowledge graph according to the marketing service information with suspected inspection problems, thereby achieving the purpose of continuously improving and enriching the knowledge graph.
Preferably, after the marketing service information with the suspected inspection problem is found, the suspected inspection problem in the marketing service information with the suspected inspection problem is identified, and the risk level is identified.

S3 includes, through PDCA closed loop mode, searching the commonality of preliminary inspection knowledge map, and abstracting and summarizing it to obtain professional knowledge map, thereby further perfecting knowledge map and promoting intelligent lean management of inspection. For example, the suspected problems are traced to the source by adopting a knowledge graph technology, the accounts and the reading and checking processes are subjected to flow inspection by adopting a balance principle, different rules are arranged and grouped by adopting a gene recombination mode, and the like, so that all-around inspection is realized, and the holographic information of the sample portrait is formed. Namely, one sample has a plurality of suspected problems, and the same multi-surface correlation display and the like are realized, so that the aims of intelligent inspection and accurate inspection are realized.
And summarizing the professional knowledge map and the inspection results of the past years to form an inspection knowledge map typical case library, and filing the inspection knowledge map typical case library into an inspection expert intelligent library to serve inspection work. By summarizing the professional knowledge map and the inspection results of the past years, the intelligent inspection rules are systematically combed to form an intelligent inspection rule system, namely an inspection knowledge map typical case base. And finally, filing the information into an intelligent database of the inspection expert. With the accumulation of rules in the intelligent database of the inspection experts, the intelligent inspection has stronger and stronger capability of solving business problems.
And S4, inspecting the inspected sample according to the intelligent database of the inspection expert to determine the inspection problems of the inspected sample. The example is not limited to only checking one type of related checking rule at the same time during checking. The inspection rules can be classified and combined to form a combined knowledge graph. If the check rule related to business expansion overtime and the check rule related to power charge error are combined, a customer satisfaction degree knowledge graph is formed; and combining and refining the inspection rules related to business expansion and installation and the inspection rules related to the customer files to form a customer file knowledge graph.
And S5, gradually cleaning and positioning the inspection problems, visually displaying the inspection results, displaying the inspection results and displaying all suspected sample lists under the inspection rules.
