A Shortest Dependency Path Based Convolutional Neural Network for Protein-Protein Relation Extraction

Figure 3

The framework of sdpCNN model with 3-word window. In this example, the input sdp has 7 words (dependency relations such as “nsubj” and “dobj” are also considered as words), each word embedding is 4 dimensions, and 5 filters are used. The yellow part is the matrix representation for an input sdp; each column in the green part represents the feature map generated by a filter through (1) and (2); and the red part represents the max-pooling results by taking the maximum value over each column in the green part by (3). The arrows in red show the process of generating a feature map . The blue part is a MLP classifier with a full-connection layer and a Softmax layer.
