Problems solved by technology

[0002] In related technologies, the labeling system is established based on rules and manual methods, including soft labels and hard labels. Among them, hard labels are fixed labels manually uploaded, which requires a lot of labor costs. In addition, soft labels also have many technical defects:
[0003] (1) The soft label provides some flexible rule information as the label of the target data. However, since the attributes of the target data change with time, the soft label cannot persistently capture and analyze the target data;
[0004] (2) If the soft label is changing dynamically all the time, therefore, the soft label needs to collect real-time snapshots of the target data, thus causing a lot of data pressure

Embodiment 1

[0049] figure 1 A schematic flowchart of a label generation method according to an embodiment of the present invention is shown.

[0050] Such as figure 1 It shows a tag generation method according to an embodiment of the present invention, including: Step S102, in response to the retrieval request information, the retrieval request information includes the retrieval condition information of the first label, converting the retrieval condition information into a custom expression, and Determine the timestamp information of the custom expression; step S104, retrieve the target data corresponding to the timestamp information according to the custom expression; step S106, create a second tag for the target data in response to the retrieved target data, wherein, the first The second label corresponds to the custom expression.

[0051] In this technical solution, the retrieval condition information is converted into a custom expression in response to the retrieval request informat...

Embodiment 2

[0106] Figure 4 A schematic flowchart of a label generation method according to another embodiment of the present invention is shown.

[0107] Such as Figure 4 Shows a label generation method according to another embodiment of the present invention, including: step S402, the customer triggers the generation of a snapshot action for the soft label; step S404, generates a DSL expression supported by Elastic Search according to the retrieval condition information and submits it asynchronously to Elastic Search cluster; step S406, Elastic Search retrieves the target data and exports the target data; step S408, uploads and stores the target data to HDFS, and creates a new hard label in the label system.

[0108] The technical solution of the present invention has been described in detail above in conjunction with the accompanying drawings. The present invention proposes a label generation method, device, server and computer-readable storage medium, which converts the retrieval c...

Abstract

The invention provides a tag generation method, a device, a server and a computer-readable storage medium, wherein, the tag generation method comprises: in response to the search request information,the search request information includes the search condition information of a first tag, converting the search condition information into a user-defined expression, and determining the time stamp information of the user-defined expression; Retrieving target data corresponding to the timestamp information according to the user-defined expression; in response to the retrieved target data, a second tag is created for the target data, wherein the second tag corresponds to a custom expression. The technical proposal of the invention solves the problem that the soft tag can not carry out persistentanalysis on the target data, reduces the data pressure caused by the snapshot, and improves the user's use experience while retrieving the target data more accurately by the soft tag.

Description

technical field [0001] The present invention relates to the technical field of data analysis, in particular to a label generation method, a label generation device, a server and a computer-readable storage medium. Background technique [0002] In related technologies, the labeling system is established based on rules and manual methods, including soft labels and hard labels. Among them, hard labels are fixed labels manually uploaded, which requires a lot of labor costs. In addition, soft labels also have many technical defects: [0003] (1) The soft label provides some flexible rule information as the label of the target data. However, since the attributes of the target data change with time, the soft label cannot persistently capture and analyze the target data; [0004] (2) If the soft label is changing dynamically all the time, the soft label needs to collect real-time snapshots of the target data, thus causing a lot of data pressure.
