Claim 4:
5. The method for information extraction according to claim 4, wherein the step of obtaining the sample set further comprises:
predicting the text to be annotated by utilizing K prediction models obtained through pre-training to obtain K pieces of triple prediction information;
when a ratio of quantity of first triple information to K is greater than a first preset threshold, adding the first triple information as the triple annotated information of the text to be annotated into the sample set, wherein the first triple information is triple information that appears in the triple prediction information but does not appear in the triple annotated information of the text to be annotated; and
when a ratio of quantity of second triple information to K is greater than a second preset threshold, deleting the second triple information from the triple annotated information of the text to be annotated, wherein the second triple information is triple information that appears in the triple annotated information of the text to be annotated but does not appear in the triple prediction information.
