Weapon equipment entity relation extraction method based on combination of pre-training model and rule

The invention discloses a weapon equipment entity relationship extraction method based on combination of a pre-training model and rules, and relates to the technical field of information extraction. Processing the weapon equipment text data set to obtain two entities of weapon equipment and attribute values thereof and an entity relationship; the method comprises the following steps of: constructing a weapon equipment entity relationship extraction model by adopting a method of combining a pre-training model and rule knowledge, firstly completing preliminary extraction of entity relationships by using the pre-training model, and then introducing the entity relationships into a filtering and adjusting module to screen extraction results to obtain a filtered and adjusted entity relationship set R1; then, an entity relationship extraction model based on rule knowledge is used for carrying out entity relationship re-extraction on the weapon equipment text data set, and an entity relationship set R2 is obtained; a
