Embodiment Construction

[0072] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0073] In view of the problems existing in the manual extraction method in the prior art, the inventor of this case conducted research:

[0074] The original idea was to use a rule-based element extraction method. However, this method needs to design more rules. This process requires a lot of manual intervention, and the scope of application of this method is relatively small, and it is only suitable for texts with relatively fixed forms (such as , a complaint...

Abstract

The invention provides an element extraction method, device and equipment and a storage medium, and the method comprises the steps: obtaining a target text and an element label defined based on an element extraction demand; extracting target element contents corresponding to the element tags from the target text; extracting an object reference word matched with the target element content from thetarget text to serve as a target object reference word corresponding to the element label; and determining a triple consisting of the element label, the target element content corresponding to the element label and the target object anaphora as an element extraction result of the target text. According to the element extraction method provided by the invention, the elements can be automatically, efficiently and accurately extracted from the target text.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to an element extraction method, device, equipment and storage medium. Background technique [0002] At some point, based on data analysis needs, it is necessary to extract some elements from some texts. For example, in the judicial field, for judges, prosecutors, public security and other front-line staff of public security and law, any link in handling a case is inseparable from a large number of In the processing of files (such as indictment, interrogation transcripts, interrogation transcripts, trial transcripts, judgments, etc.), in order to understand the case, the staff often need to read a large number of files repeatedly to obtain the elements of the case (that is, the content related to the case). [0003] At present, the extraction of elements in the text is mostly done by manual reading. However, the manual extraction of elements is time-consuming a...
