We describe two systems for semantic relation classification with which we participated in the SemEval 2018 Task 7, subtask 1 on semantic relation classification: an SVM model and a CNN model. Both models combine dense pretrained word2vec features and hancrafted sparse features. For training the models, we combine the two datasets provided for the subtasks in order to balance the under-represented classes. The SVM model performed better than CNN, achieving an F1-macro score of 69.98% on subtask 1.1 and 75.69% on subtask 1.2. The system ranked 7th among 28 submissions on subtask 1.1 and 7th among 20 submissions on subtask 1.2.
