Classifying relations in clinical narratives using segment graph convolutional and recurrent neural networks (Seg-GCRNs)

In this study, the relations between 2 medical concepts are classified by simultaneously learning representations of text segments in the context of sentence syntactic dependency: preceding, concept1, middle, concept2, and succeeding segments. Seg-GCRN was systematically evaluated on the i2b2/VA relation classification challenge datasets. |
