IPC: G06F40/295
Filed: 2021-03-12
Abstract: A method and device for entity tagging, applied in the field of artificial intelligence. In the method, a processor can update a first sequence tagging model by using N mask vectors corresponding to N sample sets. M dimensions of each mask vector correspond to M named entities, and therefore, each mask vector can reflect that some of the named entities are concerned and the remaining named entities are not concerned. Thus, in one update of a sequence tagging model, the processor can adjust parameters corresponding to some of the named entities but does not adjust parameters corresponding to the remaining named entities; and after being updated once or multiple times, a second sequence tagging model can predict prediction statements of different corpora, avoiding the need to train M different entity tagging models for the M sample sets, so that the complexity can be reduced, and the performance of entity tagging is facilitated to improve.
