N2 - Incorporating conventional, unsupervised features into a neural architecture has the potential to improve modeling effectiveness, but this aspect is otten overlooked in the research of deep learning models for information retrieval. We investigate this incorporation in the context of answer sentence selection, and show that combining a set of query matching, readability, and query focus features into a simple convolutional neural network can lead to markedly increased effectiveness. Our results on two standard question-Answering datasets show the effectiveness of the combined model.
