Abstract
A text entity extraction method, apparatus, and storage medium are provided. The method includes determining candidate text entities in a target text. Portions of the candidate text entities are combined to generate candidate segmentation combinations corresponding to the target text, the candidate text entities in each candidate segmentation combination being different. A combination probability corresponding to each candidate segmentation combination is calculated, where the combination probability is a probability that grammar is correct when the target text uses the candidate segmentation combination. A target segmentation combination corresponding to the target text is determined according to the combination probabilities. A text entity is extracted from the target text according to the target segmentation combination.
