Problems solved by technology

In the process of data processing, there will be data tables from various sources, and each data table has different fields. It is necessary to identify the corresponding data elements based on the fields in the data table. Currently, manual methods are usually used. Recognition, although the accuracy is relatively high, but the efficiency is extremely low
When the amount of data is small, the manual method can still be used. If the amount of data is large, the manual method will become unrealistic

Embodiment Construction

[0044] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0045] The steps shown in the flowcharts of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0046] The embodiment of the present invention can identify data elements in the knowledge base based on the accumulation of the existing knowledge base and the fields in the data table.

[0047] Such as figure 1 As shown, the method for matching the fie...

Abstract

The invention discloses a method and device for matching fields of a data table with data elements of a knowledge base, and the method comprises the steps of carrying out the word segmentation of thefields in the data table, and building the feature vectors of the fields; and searching a feature vector library of a knowledge base according to the feature vectors of the fields, carrying out similarity matching on the feature vector library and the feature vectors of the data elements in the feature vector library, and determining the matched data elements when the matching is passed. The embodiment of the invention can be applied to the preprocessing process when the data table is accessed, and the management efficiency and the accuracy are improved.

Description

technical field [0001] The invention relates to the field of databases, in particular to a method and a device for matching fields of a data table with data elements of a knowledge base. Background technique [0002] The use of data elements can standardize and classify the names, types, and values ​​of industry data. Data elements themselves are also data. In the process of data governance, whether standardized governance can be achieved directly determines the efficiency and quality of data governance. For data tables from various sources, there may be cases where the business meaning is consistent, but the field information is inconsistent. When getting an original data table, how to accurately and quickly find the data elements corresponding to the fields of the data table from the existing knowledge base is a key part for achieving fast and efficient standardized governance. [0003] At present, with the gradual establishment of data element standards, data elements ar...
