Abstract:
Embodiments of the present disclosure relate to an information acquisition method and apparatus, a device, and a medium. The method comprises: configuring a label table corresponding to each sample sentence in a sample set, row characters and column characters of the label table being configured in the same way according to a character order of the corresponding sample sentence, and annotating corresponding information category labels for every cell composed of a row character and a column character in the label table; performing model training using each sample sentence as input information of a model to be trained and the corresponding label table as output information of the model to be trained; and generating an information extraction model according to trained model parameters, so as to extract target sentence information according to the information extraction model. Therefore, the label table is constructed by means of using the characters of the sentence and a category of sentence characters or inter-character information annotated in the label table, such that an information extraction model trained on the basis of the label table can efficiently and accurately extract information such as the information category of a related sentence.
