Embodiment 1

[0035] Such as figure 1 As shown, the embodiment of the present invention provides a semantic analysis-based method for extracting and processing unstructured tabular data for power grid regulation, including the following steps:

[0036] (1) Obtain and preprocess the unstructured original table text of the power grid;

[0037] The preprocessing specifically includes: removing meaningless symbols and words in the original table text based on the pre-built stop word dictionary, and simplifying the table format of the original table text; the stop word dictionary builds a semantic recognition module based on artificial summary.

[0038] (2) Automatically annotate the preprocessed original table text through the pre-built semantic recognition model;

[0039] (3) Parse the data in the preprocessed original table text based on the labeling result;

[0040] (4) Arranging the analysis results into a preset structured table to generate a structured table text.

[0041] Such as fi...

Embodiment 2

[0053] An embodiment of the present invention provides a device for extracting and processing unstructured table data for power grid regulation based on semantic analysis, including

[0054] The data acquisition module is used to acquire the unstructured original table text of the power grid and perform preprocessing;

[0055] The data labeling module is used to automatically label the preprocessed original table text through the pre-built semantic recognition model;

[0056] The data parsing module is used for parsing the data in the preprocessed original table text based on the labeling result;

[0057] The data generation module is used to organize the analysis results into a preset structured table to generate structured table text.

Embodiment 3

[0059] Based on Embodiment 1, the embodiment of the present invention provides a semantic analysis-based device for extracting and processing unstructured tabular data for power grid regulation, including a processor and a storage medium;

[0060] The storage medium is used to store instructions;

[0061] The processor is configured to operate in accordance with the instructions to perform the steps according to the methods described above.

Abstract

The invention discloses a power grid regulation and control unstructured table data extraction processing method and device based on semantic analysis and a storage medium. The method comprises the steps that a power grid unstructured original table text is acquired and preprocessed; automatically labeling the preprocessed original table text through a pre-constructed semantic recognition model; analyzing data in the preprocessed original table text based on a labeling result; sorting the analysis result into a preset structured table to generate a structured table text; according to the method, the problem of power grid regulation and control unstructured table data extraction processing can be solved, so that knowledge support is provided for intelligent control.

Description

technical field [0001] The invention relates to a method, device and storage medium for extracting and processing unstructured form data of power grid regulation based on semantic analysis, and belongs to the technical field of electric power regulation. Background technique [0002] With the continuous development of smart grid and the accumulation of operating experience, power system related companies have accumulated a large amount of text data generated in the power field. In the process of power grid operation, operators still rely on operators to search for knowledge from a large number of empirical rule documents, the degree of automation and intelligence is relatively low, and the integration of system functions is not strong. Because most of these text data are manually written, unstructured text data brings great difficulties to the extraction of knowledge information, but there is often a lot of operating experience and knowledge accumulation. Making full and ef...
