Representation learning methods, which project the original features to a new feature space, have been proved to be quite effective for this task. However, these unsupervised methods neglect the domain information of the input and are not(More)
Modeling interactions between two sentences is crucial for a number of natural language processing tasks including Answer Selection, Dialogue Act Analysis , etc. While deep learning methods like Recurrent Neural Network or Convo-lutional Neural Network have been proved to be powerful for sentence modeling, prior studies paid less attention on interactions(More)
