Artificial intelligence-based named entity recognition method and apparatus, and electronic device

An artificial intelligence (AI)-based named entity recognition (NER) apparatus, comprising:

• a vector transformation device that is configured to perform vector transformation processing on text elements in a to-be-recognized text to obtain text representations of the text elements;
• a construction device that is configured to construct a candidate entity phrase based on text elements that are in the to-be-recognized text and having a total quantity less than an element quantity threshold;
• an integration device that is configured to perform integration processing on text representations corresponding to the text elements in the candidate entity phrase to obtain a text representation of the candidate entity phrase;
• and
• a classification device that is configured to perform classification processing on the text representation of the candidate entity phrase to determine a category to which the candidate entity phrase belongs in a non-named entity category and a plurality of named entity categories.

A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause a processor to implement operations comprising:

• performing vector transformation processing on text elements in a to-be-recognized text to obtain text representations of the text elements;
• constructing a candidate entity phrase according to text elements that are in the to-be-recognized text, where a total quantity of the candidate entity phrase is less than an element quantity threshold;
• performing integration processing on text representations corresponding to the text elements in the candidate entity phrase to obtain a text representation of the candidate entity phrase;
• and
• performing classification processing on the text representation of the candidate entity phrase to determine a category to which the candidate entity phrase belongs in a non-named entity category and a plurality of named entity categories.
