This research aims to develop a supervised model for ranking short text pairs using deep learning techniques.
Developed a convolutional neural network architecture for reranking short text pairs.
Tested the model on TREC retrieval tasks, including Question Answering and Microblog Retrieval.
Utilized only word inputs to minimize preprocessing and manual feature engineering.
Achieved a performance improvement of about 3% in mean average precision (MAP) and mean reciprocal rank (MRR) for Question Answering over previous state-of-the-art models.
Demonstrated comparable results in tweet reranking while eliminating the need for manual feature engineering.
Showed the ability to automatically learn optimal feature representations from training data.
