Problems solved by technology

However, in this information extraction method, if any entity in the head entity or the tail entity is extracted incorrectly, it will lead to subsequent predictions of wrong entity relationships, resulting in low accuracy of the extracted structured information
[0004] Therefore, it is urgent to solve the technical problem that the existing structured information extraction technology cannot extract highly accurate structured information

Abstract

An embodiment of the invention discloses an information extraction method, device and equipment and a computer readable storage medium, and relates to the technical field of artificial intelligence. The method comprises the steps: extracting a head entity contained in an unstructured text according to a preset entity type; performing relationship classification processing on a head entity contained in the unstructured text to obtain an entity relationship corresponding to the head entity contained in the unstructured text; constructing an entity relationship problem according to the head entity and the entity relationship corresponding to the head entity; extracting a tail entity from the unstructured text, wherein the tail entity corresponds to a head entity and an entity relationship inthe entity relationship problem, and structured information contained in the unstructured text is obtained based on the head entity and the entity relationship in the entity relationship problem and the tail entity. According to the method disclosed in the technical scheme of the embodiment of the invention, the extraction accuracy of the structured information can be improved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, and in particular, to an information extraction method, apparatus, device, and computer-readable storage medium. Background technique [0002] With the research and progress of artificial intelligence technology, artificial intelligence technology has been researched and applied in many fields, such as common smart home, smart wearable devices, virtual assistants, autonomous driving, drones, robots, intelligent customer service and other fields. Artificial intelligence technology is playing an increasingly important value. For example, in the field of information extraction, artificial intelligence technology can easily automatically extract unstructured information embedded in text into structured information in the form of <head entity, entity relationship, tail entity>. [0003] At present, the commonly used structured information extraction process is: first e...
