Example Embodiment

[0034] Example 1:

[0035] as Figure 1 As shown, embodiments of the present invention provides a grid regulation unstructured table data extraction processing method based on semantic analysis, comprising the following steps:

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

[0037] Preprocessing includes: removing meaningless symbols and text from the original table text based on the pre-built stop word dictionary and simplifying the table format of the original table text; and the stop word dictionary is based on the artificial use of inductive summary to build a semantic recognition module.

[0038] (2) Automatic annotation of preprocessed original table text through pre-built semantic recognition model;

[0039] (3) Parse the data in the original table text after preprocessing based on the labeling results;

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

[0041] as Figure 2...

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...
