Embodiment Construction
[0051] The present invention will be further described below in conjunction with accompanying drawing.
[0052] Such as figure 1 As shown, a biological event extraction method based on the attention mechanism of candidate event elements includes the following steps:
[0053] Step 1. Preprocessing the training corpus, constructing the biological event extraction task into a sequence labeling task form: the training corpus used is selected from MLEE or Multi-Level Event Extraction, and the MLEE corpus extracts fine-grained events from biological literature related to cancer, where Contains named entity annotations and event annotations of biological tissues. The training corpus provides three files for each document, namely the original text file, entity annotation file, and event annotation file. The event trigger words and event trigger words are marked in the event annotation file. Events composed of trigger words and entities are processed by traversing the tagged trigger w...
