Classifying medical relations in clinical text via convolutional neural networks
Deep learning research on relation classification has achieved solid performance in the general domain. This study proposes a convolutional neural network (CNN) architecture with a multi pooling operation for medical relation classification on clinical records and explores a loss function with a category level constraint matrix. Experiments using the 2010 i2b2/VA relation corpus demonstrate these models, which do not depend on any external features, outperform previous single model methods and our best model is competitive with the existing ensemble based method.
