The invention provides a company entity recognition method, device and equipment based on bid invitation information and a medium, and the method comprises the steps: obtaining a text set, an organization set and a qualification type set of bid invitation and tendering information; performing data preprocessing on the text set and the organization set of the bidding and tendering information to obtain a to-be-labeled data set; annotating and processing the to-be-annotated data set by using the acquired organization data to obtain an annotated data set; and establishing an entity recognition model of BERT-BiLSTM-CRF, inputting the annotation data set into the entity recognition model, obtaining position information of the company entity in the text, and completing company entity recognition. By fusing BERT, BiLSTM and CRF, the problems in a traditional entity recognition method are solved, more accurate entity extraction can be realized, the method is suitable for texts of different types, lengths and styles,
