Abstract

The invention discloses a text structuring method aiming at power grid fault cases. The method includes: subjecting unstructured texts to named entity recognition, and constructing an entity dictionary aiming at the field of power grid to assist in entity recognition and text segmentation; extracting attribute values and attribute description state quantities, wherein the state quantities includedigital state quantities and non-digital state quantities according to types; extracting and matching digital state quantity modification attributes according to a rule-based method; detailing the non-digital state quantities to divide into phrase form based state quantities and sentence form based state quantities, and extracting respective modification attributes; according to recognized attributes and corresponding state quantities, finally generating a plurality of binary groups formed by the attributes and the corresponding state quantities to complete text structuring.

Description

technical field [0001] The invention relates to a text structuring method for grid failure cases. Background technique [0002] In the overhaul and maintenance of the power system, power grid enterprises have accumulated a large number of fault case reports. These texts include overhaul test records, inspection and defect elimination records, fault problem descriptions, fault cause descriptions, etc., mainly in unstructured forms. These descriptive information are organized through the specification and logic of natural language, and there is no predefined data model or text template. [0003] The descriptions of various equipment states are scattered in different places in the text. The purpose of text information structuring is to obtain the state quantities describing equipment failures through the analysis and processing of unstructured texts, and fill them into the predefined data model. middle. Existing text structuring methods usually only extract structured informa...
