Abstract

The invention provides a model training method and device and a data label generation method and device, and the model training method comprises the steps of obtaining first attribute information from sample data, the first attribute information at least comprising a data source and a data format of the sample data, the sample data being provided with a service label; obtaining second attribute information from the sample data, wherein the second attribute information at least comprises table description information and a table name of the sample data; determining a target label matched with the sample data from a preset label set; and storing the first attribute information, the second attribute information, the target tag and the service tag as training samples to a training sample set, so as to train a data tag generation model by using the training sample set, the data tag generation model being used for generating a corresponding service tag for the to-be-processed data. By applying the method, the data label of the unknown label data can be automatically generated by utilizing the trained data label generation model, so that the efficiency of performing label management on the data is improved, and manpower and material resources are saved.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a model training method, a method and a device for generating data labels. Background technique [0002] With the development of Internet big data, tag management has become an important part of the big data era. By defining data tags with keyword characteristics for data, it can facilitate subsequent data indexing and data search. However, with the birth of massive data, a lot of data due to historical reasons or other reasons lead to fragmented and scattered data distribution, thus forming multiple data islands. [0003] In the existing technology, in order to solve the data island, data can be sorted out manually, the data can be classified and the data labels can be defined. This method will undoubtedly consume a lot of manpower and material resources. At the same time, due to the influence of human experience, the accuracy of the data labels defined fo...
