[0027] see figure 2 As shown, it is the first embodiment provided when the method for judging the data quality level of the present invention is implemented, and it includes the following steps:

[0028] S101: Transmitting the acquired target data group to the server; wherein, the target data group refers to data that needs to be judged by level;

[0029] S102: Extract the feature vector of each target data in the target data group, and perform character conversion on the feature vector to obtain character set data corresponding to each feature vector; wherein, the feature vector is the attribute information of the target data; if the value of a certain attribute information is empty, it means that the target data corresponding to the feature vector is incomplete;

[0030] S103: Pre-designate the level standard of inspection according to the feature vector of each target data group, so as to improve the speed and accuracy of data quality level inspection;

[0031] S104: Che...

Abstract

The invention provides a data quality grade judging method, which comprises the following steps: transmitting an obtained objective data group to a server; extracting a characteristic vector of each objective data in the objective data group and performing the character conversion on the characteristic vector so as to obtain character set data corresponding to each characteristic vector; examining the character set data according to a grade standard stored in the server so as to obtain a quality grade code of each characteristic vector; and feeding back each objective data and the corresponding quality grade code to a user. According to the method, the quality of the objective data group can be examined by the grade standard stored in the server, so that the quality grade code corresponding to the objective data group is obtained and is fed back to the user; the method is rapid in examination speed and high in accuracy; and the user can carry out a corresponding processing according to each objective data and the corresponding quality grade code.

Description

technical field [0001] The invention relates to a method for judging data quality, in particular to a method for judging a configurable data quality level based on an algorithm. Background technique [0002] With the continuous development of information technology, a large number of various types of information emerge. In the process of retrieving or entering data information in practical applications, users often find that the attributes of some data information are incomplete, or some data information contains wrong information, such as Errors in phonetic / approximate words, errors in similarities and meanings, and irregular expressions of some special symbols, etc. These incomplete information and error information will cause troubles to users, fail to meet the needs of information acquirers, and make retrieval or input accurate. The performance is reduced, which affects the user's use. This makes it particularly important to judge the quality of the retrieved informatio...
