Improved Relation Classification by Deep Recurrent Neural Networkswith Data Augmentation
Table 3: Comparison of previous relation classification systems.
['[BOLD] Model', '[BOLD] Features', '[ITALIC] F1']
The first entry in the table presents the highest performance achieved by traditional feature-based methods. \newcite2010SVM feed a variety of handcrafted features to the SVM classifier and achieve an F1-score of 82.2%.
