Embodiment Construction
[0077] The technical solutions of the present invention will be further described below in conjunction with the drawings and specific embodiments.
[0078] Such as figure 1 As shown, a multi-instance learning remote supervised relation classification method based on PCNN and Multi-level attention, including two stages, training relation classification model stage and prediction stage;
[0079] (1) Training relational classification model stage
[0080] Step 1: Preprocess the training corpus of the relational classification model
[0081] (1) Convert the original corpus data OrgData into character-level corpus data NewData;
[0082] (2) count the characters of NewData, obtain the character set CharSet, number each character, and obtain the corresponding character number set CharID of the character set;
[0083] (3) Convert the entities, relations, and sentences in each bag through CharID to obtain the bag expressed in the form of ID;
[0084] (4) Obtain the list representat...
