Before revision:  In this paper, we propose an instance-based method to find similar questions of a new question , in the sense of their relations, to predict its mentioned relation . The motivation roots in the fact that a relation can be expressed with different forms of question and these forms mostly share similar terms or concepts.
After revision:  In this paper, we propose an instance-based method to find similar questions of a new question which share the same relation, and their corresponding relation is selected as our prediction. The idea of our model roots in the fact that a relation can be expressed with different forms of question and these forms mostly share similar terms or concepts.
