The embodiment of the invention discloses an information acquisition method and device, electronic equipment and a medium, and aims to solve the problem of information extraction errors caused by document content blocking errors. The information acquisition method comprises the following steps: acquiring a to-be-processed document and analyzing the document content into a sentence sequence in a plain text format; inputting the sentence sequence into a pre-trained sentence labeling model to label the sentence sequence, and outputting a category label to which each sentence belongs; according to the category label to which each sentence belongs, dividing the sentences with the same category label in the sentence sequence into corresponding content blocks; an information extraction model is used for extracting entity information or attribute information of the content blocks, and the information extraction model corresponds to the category labels. The embodiment of the invention further provides a training schem
