DeepQA is a deep learning library for natural language processing built on top of Keras and TensorFlow. It provides high-level abstractions for NLP modeling, including text encoding, word/character embeddings, attention mechanisms, and sequence padding utilities. The library is specifically designed to make question answering tasks easier to implement while remaining useful for broader NLP applications. The project is now deprecated in favor of AllenNLP, the team’s PyTorch-based successor.
