Method and apparatus for performing structured extraction on text, device and storage medium

An electronic device, comprising:

• at least one processor;
• and
• a memory communicated with the at least one processor,
• wherein the memory stores instructions executable by the at least one processor that, when executed by the at least one processor, causes the at least one processor to perform operations comprising:
• performing a text detection on an entity text image to obtain a position and content of a text line of the entity text image;
• extracting multivariate information of the text line based on the position and the content of the text line;
• performing a feature fusion on the multivariate information of the text line to obtain a multimodal fusion feature of the text line;
• performing category and relationship reasoning based on the multimodal fusion feature of the text line to obtain a category and a relationship probability matrix of the text line;
• and
• constructing structured information of the entity text image based on the category and the relationship probability matrix of the text line.

A non-transitory computer readable storage medium, storing a computer instruction, wherein the computer instruction is used to cause a computer to perform operations, comprising:

• performing a text detection on an entity text image to obtain a position and content of a text line of the entity text image;
• extracting multivariate information of the text line based on the position and the content of the text line;
• performing a feature fusion on the multivariate information of the text line to obtain a multimodal fusion feature of the text line;
• performing category and relationship reasoning based on the multimodal fusion feature of the text line to obtain a category and a relationship probability matrix of the text line;
• and
• constructing structured information of the entity text image based on the category and the relationship probability matrix of the text line.
