Knowledge-oriented convolutional neural network for causal relation extraction from natural language texts
作者:
Highlights:
• Knowledge-oriented convolutional neural network (K-CNN) performs better than CNN.
• Word filters capture linguistic clues of causal relation and alleviate overfitting.
• Word filter selection and clustering improve the performance of K-CNN.
• Semantic features improve precision and recall for complex causal relations.
• Combination of knowledge and data improves the performance of deep learning model.
