Abstract

The invention provides a model training method and device, an information extraction method and device, equipment and a storage medium, and the information extraction method comprises the steps: carrying out the classification recognition and sequence labeling of a to-be-extracted sentence text according to a reading understanding model obtained through training, and obtaining a classification recognition result and a sequence labeling result of the to-be-extracted sentence text, the sequence labeling result is used for indicating field values corresponding to multiple preset fields in the sentence text to be extracted, the field values corresponding to the multiple preset fields are associated according to the association relation of the multiple preset fields, structured data are obtained, and the structured data comprise the multiple preset fields and the field values corresponding to the multiple preset fields. According to the method, the field values corresponding to the multiple preset fields can be extracted, and mutual association of the field values can be realized to obtain the structured data.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, and specifically relates to a model training method, an information extraction method, a device, a device, and a storage medium. Background technique [0002] With the development of artificial intelligence technology, it has become a trend to use artificial intelligence technology to extract important information from massive unstructured announcements. Usually, before information extraction, it is necessary to define the field names to be extracted in advance, and then based on The field name extracts the corresponding field value to store in the structured database. [0003] Among the information extraction methods currently provided, one is based on rule extraction, which pre-defines the extraction rules and extracts field values ​​by writing regular rules. The other is based on sequence labeling, predicting a pre-defined The defined label, and then decode the label...
