This is a Kaggle competition hold by Quora, it has already finished six months ago. The goal of this competition is encouraging competitors to develop a machine learning and natural language processing system to classify whether question pairs are duplicates or not. In other words, this semantic question matching problem can be defined as follows: for question pair q1 and q2, train a deep learning model to predict the function:
𝑓(𝑞1, 𝑞2) → 0 𝑜𝑟 1
0 represents that q1 and q2 are not duplicate.
