Embodiment
[0055] Based on the above description of specific implementations of the method and system involved in the present invention, description will be made in conjunction with specific embodiments.
[0056] This embodiment uses the corpus provided by task 2 to identify drug-induced disease (chemical-induced disease, CID) relationship in the CDR (drug-disease relationship) challenge proposed by BioCreative V in 2015. The CDR corpus has annotated 1,500 articles, including 4,409 drugs, 5,818 diseases, and 3,116 drug-disease relationships at the conceptual level. It is currently the largest drug-disease relationship dataset. The CDR corpus contains a total of 1500 Medline articles including abstracts and titles only, and 500 articles for each data set in the training set, development set, and test set. During the experiment, the initial training set and development set were combined to expand the training data set. The instances in the merged union are randomly divided into 10 equal s...
