Embodiment Construction
[0039] The present invention will be further described below in conjunction with accompanying drawing.
[0040] Such as figure 1 As shown, a biomedical event trigger word recognition method based on feature automatic learning, including the following steps:
[0041] Step 1, data preprocessing, including the processing of the original corpus and the introduction of external data resources, specifically including the following sub-steps:
[0042] (a) Since the proportion of biomedical events across sentences in the corpus is very small, the detection of trigger words for biomedical events in the method of the present invention is based on sentences, and the sentence tool GeniaSentenceSplitter in the field of biomedicine is used to analyze all txt in the experimental corpus The data of the file is segmented into sentences;
[0043] (b) In order to better mine the semantic and grammatical information of biomedical event trigger words, the method of the present invention introduc...
